This is the hardware hack for the EX/HX. I haven't tried it 'cause "Next
week I'm buying another computer". (See date of EchoMail post)

Well I dont remember exactly WHO wanted this so I hope this person gets
this message...
Here is a list of what you need to make a standard IBM card edge
expansion slot (for a hard drive, etc)
1> Desc : PLUS Expansion Adaptor
Part #: 25-1016
Price : $14.95
Where : Radio Shack
2> Desc : 62 Pin Female card edge connector (PC/XT Bus connector)
Part #: 276-1453 (New for '89)
Price : $2.95
Where : Radio Shack
3> Desc : 62 Pin Female Header from PLUS Card (AJ-7114-connector #)
Part #: 25-1031
Price : $8.03
Where : Radio Shack National Parts
First off remove the pins from #1 (PLUS card).
Then solder the edge connector (#2) to the HOLES of the pins that you
removed on #1. You will have to bend the pins a little to make them
fit. Get them as far inside the holes as possible but for the most
part the solder should run into them and hold well. Next cut the
gold edge fingers of #1 (the easiest way is to put it on a sanding
wheel and it will grind them down quickly without messing them up)
leaving about 1/8 inch of the gold left over. Then solder the female
pin connector (#3) to the gold fingers on the PLUS card. Next thing
to do is to either cut or grind the PLUS card down to the edges of
the white lines that surround the female pin connector. Finally check
the connector for shorts (a continuity check works fine. Check one
and the next one ahead and make sure only the selected one has a
complete circuit) that's about it....cep't make sure the card is
plugged in correctly (hehe)....
