Thanks Briel's SuperEncoder is exactly what I need!

here a summary:

When I first got my apple ii+ none of the keys except the reset escape
and control keys worked. I looked up a schematic and replaced most of
the components and the keyboard encoder IC.

Encoder chip that I purchased on ebay did not work it was showing the
wrong characters for the buttons like a ? when I pressed any of the
numbers etc. I guess it has to be specifically programmed for the
computer you are trying to use it on.

Vince Briel's  super encoder is a new production encoder for the Apple
ii/ii+ you can use the original keyboard and/or ps/2 keyboard so I
couldn't pass it up! it's at http://www.brielcomputers.com/ I
exchanged some emails with him and it sounds like it will do the
trick! He's a super nice guy.

I had a heck of a time finding a replacement cable for apple ii+
keyboard to motherboard jumper cord or wire or whatever you call it
the dip 16 connector. the pins were very brittle and broke off just by
removing the cable. Vince was kind enough to point me in the right
direction. Digikey part# C6PPS-1606G-ND. I guess they actually make
them when you order them but they are considered "in stock" so they
were not on back order and should ship soon and the cable only cost
like $2.75.
