I like the DIY Pic, it doesn't need the MAX232 chip after all, as the PIC
will output the correct baud. A one chip solution. Cool. It does need to
be modified to output 1200 baud, otherwise it should be easy to adapt to
do the Programmers Keyboard.
The RESET line could interact for the MCLR line to send a
"Keyboard Present" signal back. This only needs to be
identified as what character is sent to the 9100 to let it know the
keyboard is there. I think a space or return is all that is
required. Some sort of acknowledgement that the RESET signal from the
9100 was received by the keyboard.
This hardly needs a PCB, more a solder blob on a socket then wrapped in
tape or built into a DIN plug that has an AT/PC style keyboard connector
on the other end of the wire.
A one evening project! Now for someone to transfer the code into a file
to be dumped into the PIC... I have a PIC burner and will freely burn PIC
chips for folks that send them to me if I get the code.

$99 let's keep looking

DIY 68HC705 project, I think
it would just require remapping some of the ASCII codes. I believe source
is there too. Uses a AT keyboard.
Also links to a 68HC11 version.

Pic Microcontroller version. I don't think he supported all the Function
keys but I imagine he would be helpful if asked.
Unfortunately I haven't had time to play with any of these but I think the 2
DIY projects are the solution we are looking for & relatively cheap.
As for the Reset issue, I don't know. Didn't you have a fake out for that
John?
