001- What is the easiest way to download files from Apple II sites?
Modern PC internet browsers like netscape and Internet Explorer have
spoiled much of the challenge of connecting to sites on the net. For example,
entering
ftp://ground.ecn.uiowa.edu/2/apple2/apple16/Games/
in IE's "Address" box gets you to Ground's IIgs games folder ready to download
with just a mouse click.
Downloading via a Browser
Some major Apple II sites are FTP sites-- places you get to via an ftp://
URL. FTP connections tend have a pretty raw look-- instead of colorful
backgrounds, pictures, fancy buttons, etc., what you see is mainly text showing
folder and file names. You may get folder icons and, perhaps, some simple icon
next to each file name.
Today, many Apple II sites are web sites with pages you get to via an
http:// URL. Often, web download sites will offer a relatively fancy display
listing titles with descriptions and, by each title, a button to click to do
the download. Other web sites may do without html pages and not be much fancier
than an FTP site.
Whether FTP or HTTP, you usually just click a button or file name to start
the download process. An exception might be when the file is a Text file you
wish to download; for Text file downloads you may need to right-click or SHIFT-
click on the item to get some sort of 'Save file' dialogue.
If the file is some binary type (like .shk, .dsk, .zip, etc.), just
clicking on the download link or button should bring up a Save dialogue-- like
an alert asking if you wish to Save the file-- or take you immediately to a
Save window.
When regular (left) clicking gets you to a Save dialogue or window, it
indicates that the download page's server knows that the item is not Text or
that your browser is one which defaults to binary mode when the filetype is not
recognized. Either way, the odds favor getting a good download.
Many Apple II sites are on servers which have no difficulty recognizing PC
filetypes like .zip and .bin but do not recognize popular Apple II filetype
designations such as .shk, .sdk, and .dsk If a regular click on a download link
or button for a shk, or other binary file results in a dump of garbage text to
your screen, it means your browser thinks it is supposed to download some kind
of Text file.
Right-clicking or SHIFT-clicking should allow you to avoid the garbage and
get a Save dialogue and download the file. However, since the browser thinks
it's Text, the resulting file will probably have the linefeed character code
($0A) added after every $0D in the file which is not followed by an $0A. So,
almost certainly, the download will be corrupted.
One try at a workaround if you are on an http:// site is to try the
place's ftp:// URL if it has one. If that doesn't help, contacting the FTP site
via an FTP program will almost certainly work.
If you are using an older browser, going to a newer version of IE or
Netscape could get the job done.
If you have not defined the particular Apple II filetype in Windows and/or
your browser, that may help. (See Geoff Weiss's page which talks about making
web browsers aware of Apple II file types for ftp connections at
http://www.gwlink.net/geoff/IIdownload.html .)
If the item is available from another place, you may find that going there
for your download solves the problem.
Another pretty good alternative is to go ahead and download the .shk, etc.
file and use a PC utility named "Uncook" to try producing a copy with the
corruption removed.
Uncook was 'discovered' by GS Ed (manager of the ACN Florida archive); and
tests indicate that it usually succeeds when the file is corrupted. If the file
is not corrupted, Uncook may produce a messed up copy! Fortunately, it is
pretty easy to tell when the latter occurs.
If the result of Uncook is a file just 2-4 or so bytes smaller, the
original is probably good and the Uncook is bad. If the new (Uncooked) file is
known to be the correct size (like it's a 143,360-byte .dsk file) or if it is
many bytes smaller, or if the site is known to deliver corrupted files, then
the Uncooked file is probably good. And, if there is any doubt, you can always
try using both files-- e.g. the .sdk file which gets you a "bad data" error
during unshrinking is the bad one.
Uncook.zip is available from GS WorldView's "Download Help" page at
http://apple2.org.za/gswv/a2zine/DownloadHelp.htm . To get Uncook, click on
"Download" near the bottom of the page.
Downloading via an FTP Program
A slightly different approach is to use a good FTP program (often called
an "FTP client"), such as WS_FTP or Cute FTP. It is easier to download (or
upload) multiple files, speed is usually a bit better, and, since you can force
binary mode, direct FTP is not much bothered with file type recognition.
To connect to an FTP site you can run a dial-up program to establish
contact with your Internet Service Provider (ISP) and start your FTP program.
If you are on the net under Netscape, 'Explorer, etc., then you are already
connected to your ISP and can start your FTP program as a new task.
After starting your FTP program, you can select the FTP site you want from
a list you've created. The list, also called a "profile list", contains ...
o- the site's internet name-- such as "ground.ecn.uiowa.edu" (Note: there are
no "/" folder separators in this entry.)
o- the particular folder or directory you want to begin with-- such as
"/2/apple2"
o- and the folder on your computer for downloads-- such as "C:\Downloads".
Other information, such as the kind of connection (usually "Unix
standard") and the password you send to the site-- usually you will log-in as
"anonymous" and use your email address as the password-- are entered more or
less automatically when you first create a site's profile entry. (To create a
new entry you will usually just click "New", "Create New", etc. instead of
picking a site to contact.)
When the connection is made, you will see a list of files and folders in
the folder you have entered. If you open one of the folders, you will get a new
listing of files and folders contained in the selected folder. You can
'navigate' deeper into the archive and reach, say, Ground's
/2/apple2/Collections/AOL/Games folder; and you can navigate backward to, say,
/2/apple2/Collections and explore some other collection, such as
/2/apple2/Collections/1WSW.
You can, also, change the the drive and folder on your hard disk to which
you wish to download. For example, the default "local" folder may be
C:\Downloads whenever you connect to Ground. If you want downloads to go into
D:\TempStuff, you can pick this destination. Another situation in which you may
wish to change the local folder is when uploading files to a site.
Practically all programs and compressed disks will be in .SHK, .SDK, .DSK,
or some other "binary" form. In fact, "Binary" should nearly always be your
download/upload mode setting, even when downloading (or uploading) Text files.
About the only exception would be when dealing with a binscii archive site
which can not handle binary.
In general, when downloading an Apple II .SHK, .ZIP, etc. file, it is best
to avoid letting any "helper" applications process the file during download.
Usually, it is best to unZIP .zip and .gz files on the PC but, still, after you
have completed the download. Your Apple II can take care of un-Shrinking and
most other kinds of processing which may be required after the file is
downloaded and transferred from the PC (or Mac).
To download one or more files you click-highlight each file you want.
Then, you click some button-- such as an arrow symbol pointing to your
C:\Downloads folder-- to start the download.
Usually everything will go smoothly and the files will appear on hard disk
in your target folder (e.g. C:\Downloads). If you use a dedicated ftp utility
you will, usually, be able to see the exact length of a file on the site's file
list. One good check for a successful download is to compare file lengths
displayed in your target folder with those shown in the FTP site's file list.
If you do straight downloads with no processing, there should be no differences
for binary transfers. (Text file transfers in Text mode often result in small
length changes.)
----------------------------
002- Some of my downloads are bad; what's wrong?
If the exact length of a downloaded file is different than its exact
length on the download site (e.g. as shown via your FTP client program), the
download is probably corrupted. (Text files are something of an exception--
i.e. the download length may be different and the file may have characters
added; but, usually, the "corruption" has no damaging impact.)
A common reason for getting a bad download is that a binary file-- e.g. a
.shk, .dsk, etc. file-- was downloaded in Text mode. (See discussion about this
in Q&A 001 above.) An FTP program should be set to "Binary" before doing most
downloads from ftp sites. If using a browser, pick one which defaults to binary
mode for unrecognized file types (e.g. a current version of Internet Explorer).
Some files may seem to be corrupted-- i.e. 'not work right'-- even if a
length check shows that the download size is identical to the file's size on an
ftp site. One possibility is that the file was corrupted somewhere in the
upload process. This is fairly rare for files made available for download.
A few Apple II files still include a Binary II prefix. This may cause the
file to appear corrupted to some utility you try to use on a PC; but, it will
work fine once transferred to your Apple II. (Normally, a modern Apple II
telecom program such as Spectrum or ProTERM will be set to automatically strip
off the Binary II prefix during transfer. GS-ShrinkIt and 8-bit ShrinkIt will
remove a Binary II prefix from .shk, etc. ShrinkIt files.)
The file may be okay but incorrectly named. For example, an .sys or .bin
file may be shrinked but still uploaded as an ".sys" or ".bin" file (instead of
".shk"). Or, an .shk file may be uploaded in binscii form as an ".shk" file.
(Such a file should end with ".bsq".) When a downloaded .shk or .sdk file is
rejected by ShrinkIt, it's a good idea to try running it through Binscii or
GScii. Sometimes the result will be a genuine .shk or .sdk file.
Other kinds of files are just misunderstood. A user who downloads a 'disk
image' file named NarfGame.dsk.gz" may conclude it is "corrupted" when it is
rejected by an emulator program or fails to convert to diskette with DSK2FILE
or ASIMOV. But, all that's required is to decompress the .gz file using WinZIP
or similar utility to produce a true .dsk disk image file.
A source of possible confusion for IIgs users is the occasional .shk or
.sdk file which looks fine but is rejected as damaged by GS-ShrinkIt. The
problem may be that the file was created by a Mac owner. Sometimes these Mac-
created Shrink files unShrink fine using GS-ShrinkIt; sometimes, not. Before
trashing a "damaged" .shk or .sdk IIgs file, try running it through Balloon.

From: Greg J. Buchner
Balloon is a IIGS desk accessory that was put out by Ego Systems...it
handles ShrinkIt archives from anywhere you can access a New Desk Accessory on
the IIGS. For the Mac, you'd use Shrink II.

003- Are there any kinds of files I should process on the
PC (or Mac) before transfer to my Apple II?
Yes. Many old games and other interesting wares downloaded from "emulator"
sites like Asimov will arrive as .gz files. These will, almost always, be
compressed 5.25" disk image (DSK) files. They should be un-compressed on the PC
via WinZIP before being sent to your Apple II. This avoids a messy de-
compression process on the Apple and makes the DSK file available on the PC (or
Mac) should you wish to use it with AppleWin or some other A2 emulator program.
Note: If you are running an FTP program under plain DOS or Windows 3.x, long
file names will be truncated to fit PC's old "8 and 3" format. A .gz file may
not show up in your C:\UPDOWN (or whatever) directory with the ".gz" suffix. It
is still a .gz file and will not be useful as a disk image (DSK) file until it
is uncompressed. The usual size of a 5.25" disk image file is about 143kB.
Other chores you will want to handle on the PC before sending a file to
your Apple II include converting .HTM (HTML) files to text and splitting up
very large Text files. Similarly, it will be easier to view, process, and
convert most large graphics files on the PC.
----------------------------
004- I need some help with uploading. I uploaded a large file to
an Apple II ftp site but nobody seems able to download it
without ending up with garbage. What's wrong?
Uploading files to an FTP site is a fairly simple process-- basically,
it's pretty close to the reverse of downloading described above. For example,
to upload a group of Apple IIgs files named "NARFGAME" you would ...
o On the GS, use GS-ShrinkIt to created a single compressed file
containing the NARFGAME files. The new .SHK file could be named
"NARFGAME.SHK". (On an Apple IIe or other 8-bit Apple II, you
could use an 8-bit version of ShrinkIt to compress the NARFGAME
files.)
o Use Spectrum or some other A2 telecom program to NULL modem
NARFGAME.SHK to, say, the PC's C:\UPDOWN folder using Z-modem
protocol.(Z-modem is easiest; but, other protocols, like X-modem,
are fine. Mainly, both telecom programs involved in the transfer,
Apple II and PC, need to be set to the same protocol.)
o Dial-up your ISP-- no need if you are already connected via
Netscape, 'Explorer, or some other browser or application.
Uploading via a Browser
o If you are running Netscape or some similar browser, you can do
the upload very easily to one of several ftp sites. (Some ftp
sites may not permit uploading from a browser. Major Apple II
sites which will include Asimov, Ground, and TFFE.)
Go to the site's upload URL-- e.g. you might type in
ftp://ground.ecn.uiowa.edu/2/apple2/ (or click your bookmark for
"Ground") and click on the upload/ folder to open it.
Note1: The folder for uploads will usually be named "upload",
"uploads", or "incoming". Sometimes, there will be folders inside,
like apple2/, apple2gs/, etc. which you should open depending
upon where you think your stuff fits.
Note2: Some sites will show the current contents of the uploads
folder and some will not. Often you will see a nearly blank
screen.
Open a window for the folder on your system which has the file or
files you want to upload. For example, you may want to upload the
file NARFGAME.SHK which is in the C:\NeatGames\ folder on your
hard disk. So, you would open a window for C:\NeatGames\.
Select (click on) the files to upload and drag them onto the
uploads page display-- you would click on NARFGAME.SHK and drag it
onto the part of your screen showing the uploads page display
(which may be blank).
Click "Yes" when asked if you want to upload the file(s).
If the site accepts your upload you will get some kind of message
indicating this somewhere on your screen-- maybe at the bottom--
saying "upload successful", "upload done", etc..
Uploading via an FTP program
o If you prefer using an ftp program (e.g. WS_FTP, Cute FTP, etc.)
or the ftp site will not permit browser uploads, start your ftp
program.
Select the desired FTP site's name in your "profiles list" (or,
if necessary, create the profile entry) and connect with the
FTP site.
Navigate to the FTP site's uploads folder-- usually, it will be
named "upload", "uploads", or "incoming". There may be folders
inside this one (like apple2/, apple2gs/, etc.) to open depending
upon what sort of stuff you are uploading.
Note: you may or may not see any files listed when in a site's
Uploads folder. Some FTP sites hide file names in this folder
and/or restrict folder access to upload-only.
For .shk, .dsk, and most other program files you upload, make
sure 'transfer mode' is set to "binary". (For Text files, mode
can be "text" or "ASCII"; however, "binary" mode is fine for
Text uploads.)
Highlight "NARFGAME.SHK" (and any other binary mode files to
upload) in the listing of files in your C:\UPDOWN folder.
Click an arrow button (or whatever) to start the transfer to
the FTP site's uploads folder.
If the upload is successful, you will usually get a message like
"transfer complete" on your ftp program's display.
With a little experience everything is nearly 'automatic'. However, there
are a few common mistakes which can ruin an upload:
o Probably, the most common error is failing to make sure "binary" is set
(check-marked, etc.) as the transfer mode when an .SHK file or other non-Text
file is uploaded using an ftp program. Basically, you should use binary mode
for all uploads to modern ftp sites. If some site complains when a .txt file is
uploaded in binary mode, use "text" (or "ASCII") mode for the Text file.
o Many Apple II users seem to feel that, because "Binary Up"-- an option which
adds a Binary II header-- is available on their telecom program, it should be
used for all transfers. It is best to turn OFF any Spectrum (ProTerm, etc.)
option which adds a Binary II header. (Also, you should _not_ use GS-ShrinkIt's
option to add a Binary II header.) A Binary II header renders a file useless
until the header is stripped off; so, for example, any Text file with the
header will be un-readable by a PC. If a downloader does not have an A2 telecom
program which automatically strips off the header during NULL modem transfers
(or if "Binary Down" is turned OFF), the Text file will look like garbage on
the Apple II as well.
o Too many old-time Apple II users still insist upon doing a binscii
conversion of all .SHK files before uploading them. When, as sometimes happens,
a binscii'd .SHK file is uploaded as an ".SHK" file, downloaders end up with a
".SHK file which ShrinkIt cannot unshrink". Except for uploads to text-oriented
services like comp.binaries.apple2, binscii is not necessary on the modern
internet.
o Sometimes, a user will NULL modem an Apple Text file to PC using a block
transfer protocol (like Z-modem) and, then, upload the file as Text intended to
be readable on-line. Such a file will, usually, be a mess when viewed on a PC.
o Mac owners sometimes use the Mac version of ShrinkIt to create a ".SHK"
archive of Apple II files which is then uploaded to an Apple II FTP site. The
result is another 'mystery .SHK file' which Apple II users cannot unshrink.
.SHK files uploaded to an Apple II FTP site should be created on an Apple II
using an Apple II version of ShrinkIt.
In short, most of the common uploading errors are the result of
carelessness or of doing something which is unnecessary. A good uploading 'rule
of thumb' is "Keep it simple".
----------------------------
005- What kinds of files should I upload to which sites?
I. Ground, TFFE, and most other Apple II ftp sites
These sites prefer .SHK files for stuff intended to run or be accessed on
an Apple II. For example, a game which includes a program file, text Readme
file, and folder of pic files would be shrinked into an .SHK file.
It is best to Shrink even compressed picture, small binary, and icon files
and upload them as .SHK files because everyone is used to dealing with .SHK
files and the filetype of shrinked files is preserved.
ProDOS diskettes should, usually, be uploaded as a collection of files in
a regular .SHK file. This uses less space than a whole-disk archive file.
DOS 3.3 diskettes should be uploaded as whole-disk archive .SDK files.
(That is, you have an .SHK whole-disk archive but you change its name to end
with ".SDK".)
Pictures and diagrams you want to be both useable on an Apple II and
viewable on-line should be converted to .GIF form (e.g. via Super Convert) and
uploaded in this form.
If you have several pictures or diagrams you want to be accessible off-
line on an Apple II as well as a PC, Mac, etc., you can convert them to .GIF
form, place them all in a .ZIP file on your PC, and upload the .ZIP file.
All of the above would be uploaded in "binary" mode.
Text which is intended to be readable on-line should be uploaded as plain
Text in "ASCII" or "Text" mode or, on most sites today, in binary mode.
Whenever you upload a game, utility, etc. to an ftp site, it's a good idea
to also upload a brief Text file with a description of the uploaded item. For
example, after uploading NARFGAME2.SHK (in binary mode), you could upload a
brief description in a Text file named NARFGAME.TXT (in Text or binary mode).
II. Asimov and other Apple II emulator ftp sites
Upload files will, generally, be individual DOS 3.3 or ProDOS disk image
(.DSK) files created on an Apple II by DSK2FILE or ASIMOV. Upload in binary
mode.
III. Comp.binaries.apple2
Programs, etc. posted to this newsgroup are normally .SHK files which have
been Binscii'd-- i.e. after Shrinking, the file is changed to Text form via a
binscii utility.
IV. Comp.sources.apple2
Source files posted to this newsgroup are normally plain Text.

006- How can I read & send email and newsgroup messages
with my Apple II?
You can use a program by Tom Larson named "2qwk!". Many PC-based BBS's
and other servers have hidden among the door programs a "maildoor," which will
package all unread messages in a user's chosen news groups and make them
available for download as a single compressed file, called a QWK packet. (Hence
"2qwk", QWK access for Apple II; get it?!)
So, you have a QWK packet sent to your machine, which takes a few seconds
to a few minutes depending on how fast the modem is and how many messages there
are. Then, you can go off-line and launch 2qwk!. Selecting "Archiver" lets you
start the utility of your choice (such as Angel 0.81b, available separately) to
unpack the QWK packet and return to 2qwk!.
Now, you may select "Messages" to view your news groups, scan messages by
author and subject, and, finally, read individual messages. When you find a
post that needs a reply, you can decide how much of the message to quote and
type-in your words of wisdom. You can also haul in text from disk and, even,
pick just the right tagline (snappy words at the very end of many messages seen
on-line nowadays). Naturally, 2qwk! allows complete freedom to change a message
title along with the group to which it is to be posted and to originate new
messages.
When you are done reading and replying, you exit the program and it
creates a reply file, called a REP packet. The next time you connect, you
simply upload the REP to the maildoor. The maildoor will decide what goes where
and your messages will enter cyberspace pronto!
To use 2qwk! you will need an enhanced Apple IIe, IIc, or IIgs, with at
least 128k RAM and drive space to hold the QWK data. The program itself will
fit on a 5.25" disk with plenty of room to spare. Of course, the server to
which you connect must have a QWK-compatible maildoor. 2qwk! runs under ProDOS
2.x. It comes with QuickFix, a program to patch ProDOS, and other utility
programs to handle MSDOS-legal names.

007- With a fast modem, how can the IIe connect to the internet?
Get an Internet Service Provider that has the option of a text based shell
account. For email, Proline and METAL BBS's work well too.
----------------------------
008- I'm on the Internet and running the Lynx web browser.
It dosn't look like Netscape Navigator at all. Where do
I put in the URL?
Type "g" which will bring up a URL dialog. You can then type in the URL
and hit return.
----------------------------
009- How do I download an .SHK file through Lynx? Selecting the
link gives an unusable text dump.
Just highlight the link, but do not press return. Press "d" instead,
which will bring up the download dialog.

010- Can I send and receive FAXes using my Apple II?
If your Apple II is a IIgs, yes. There are two GS FAXing programs:
FAXination and PMPFAX.
----------------------------
011- What is a "Binary II" header?
A Binary II header is a small block of code tacked onto some Apple II
files. Sometimes, this is referred to as a "binary wrapper". Mainly, the Binary
II header contains filetype information. The purpose of Binary II is to allow
Apple II users to download files and have them show up with the correct
filetype. (Otherwise, a downloaded file tends to show up as a TXT type file.)
In order for a Binary II header to be recognized and used to supply the
filetype info, the Apple II downloading software must have its "Binary Down"
option set to ON. The problem with this is that, at least on a few popular
telecom wares (like Spectrum), setting "Binary Down" to ON will turn OFF Resume
Transfer, something you probably do not want to do when downloading over phone
lines.
When you use a PC or Mac to handle downloads and, then, NULL-modem the
files to your Apple, it makes sense to leave "Binary Down" ON for the telecom
program running on the Apple II. Resume Transfer is not necessary because you
have a direct, noise-free connection between two machines. Meanwhile, Binary
Down will automatically recognize and strip-off any Binary II header and save
the resulting file with the correct filetype.
----------------------------
012- Should I add a Binary II header to files I upload?
In general, no. Binary II is an Apple-only device which, today, is largely
unnecessary and can cause problems. Virtually the only valid use for Binary II
is to retain filetype information for .SEA self-extracting archives. (An .SEA
file with a Binary II header is a .BSE file.) The only file which significantly
benefits form a Binary II header is a self-extracting archive of GS-ShrinkIt.

013- How can I use my Apple II on the internet?
So, you have been told that you cannot get ftp or http files or images, right?
Of course, you cannot read .pdf files either because you have an obsolete
computer, right? Well, you are told wrong!
There is a list that you can subscribe to which tells you all you need to know
about emailing efficiently. It is called "ACCMAIL". To subscribe write to
LISTSERV@LISTSERV.AOL.COM with message in body:
subscribe accmail your.id
and you should be on. You can change the setting to digest, too, (which I
recommend).
So, how do you get ftp files? There are a number of addresses which will send
you ftp files which accmail tells about. I use bitftp@pucc.princeton.edu to get
ftp files by email. I think that by sending HELP to that address you will get
the rules of how to do it.
How about surfing the net? Well, I send messages to www4mail@unganisha.idrc.ca
or www4mail@web.bellanet.org with SUBJECT anything (it will be ignored) and
message:
get http://www .... .html (i.e. the URL of the document)
You can expect to receive the www-document in your email box.
If you need to look at the source files of the www-page, send message:
get http://www .... .html
You also may simply send message HELP to the above addresses, if your request
fails. This way you will find out whether or not you made a mistake in sending
your request. If the http-URL is too long (more than one line), you may expect
problems.
Some of the servers will send you image files, too, like .gif or .jpg files. I
get these files as file attachments in my mailbox. You have to experiment to
see what works for you. Some files are ready to use, others (uuencode or mime)
need to be decoded with BISCIT.
Search engines? Yes, they are available, too.
You need to know about http-URLs on keyword1 and keyword2? Send message to
www@kfs.org. In the body write this:
search keyword1 keyword2
Voila, you are in business.
If the http-URL contains a pdf-file, send message to pdf2txt@adobe.com or to
pdf2txt@sun.trace.wisc.edu with message:
http://www .... .pdf
and you will get the file back in text format.
If you want the pdf-files back in html-format, that can be done by replacing
"txt" in the URLs with "htm".
I use Proterm 3.1 for surfing by email and have my favorite addresses available
as macros.
