CALL -1370. Re-boots disk system.
Want to omit the pause when you issue
the CATALOG command and you have
more than a screenful of programs?
It's easy! Enter the monitor and
type... AE34:60 ...(DOS 3.3)
PEEK(-18070) If 150 is returned then
you are using DOS 3.3. This PEEK
works for both Applesoft & Integer.
Here's a 16/13 sector hardware mod:
(Allows you to switch between DOS
3.2 & 3.3 without Basics Disk by
simply flipping a switch).
Remove P5A chip from P5 socket.
Get the original P5 (DOS 3.2) chip.
Bend out pin 20 on both chips and
place the P5 chip on top of the P5A
chip (piggyback). Solder pins 1-19
of P5 chip to pins 1-19 of P5A chip.
Insert one end of a wire into pin
20 of the P5 socket and solder the
other end to the common (center)
connector of a SPDT switch. Insert
the 2 piggyback chips into the
P5 socket (pins 20 of both chips
should not be inserted into the
socket or connected to anything at
this time). Solder pin 20 of P5 chip
to one of the 2 free connectors on
the SPDT switch. Solder pin 20 of
P5A to other switch connector. Be
sure there are no shorts, that you
followed directions before turning
on power. Flipping switch in one
direction or the other selects be-
tween either DOS when booting.
NOTE: This will definitely VOID your
warranty. If you make this mod
you do so at YOUR OWN RISK. Had to
say that so I don't get sued (but
the mod WORKS).
For Language/Memory Card users: If you
are tired of DOS 3.3 dumping whatever
language is on your card every time you
re-boot with a PR#6, here's the fix:
Using Dan's Disk Utility or some
other similar program, read track 0,
sector $09, byte $CC (should be $81)
and change it to $10. Now when you
do a PR#6 whatever is in the
language card will still be there.
Here's 4 good POKES I'm sure you'll
find a use for. They will turn your
disk drive(s) on & off without
reading or writing. You can use
these to run the dri
