The Fluke keyboard port provides the +5 and Gnd. Page 7-5 of the 9100
Service Manual (Schematics)
1) KBDATA (Inverted and not connected other than to a pull-up
resistor)
2) KBDATA (non-inverted) Serial Data @1200 baud
3) KBRESET Reset signal (Low) to keyboard, keyboard sends some
sort of response back so 9100 'knows'
4) +5
5) Gnd

OK, looks
like there is definitely enough interest for 10-20 units. My
current plan is probably an atmel AT90S2313 or pic 16C84 for brains plus
a MAX232 part as a serial driver. Should be a very small box. I
need to dig out the pinout for the fluke keyboard port and see if I am
going to require an external power source for this and the
keyboard.
Oh the reason for the probability of the PIC
over the atmel is that I can build a parallel port pic programmer for
next to nothing and have two books on pics. I have nothing on the
atmel parts at this time. I am completely welcome to pointers
though.
And a couple people asked what I was doing the
schems / layout in. I will be upfront, this is my first
"real" project so up to now I just have hacked my way
through. So ideas there also welcomed :)

- I am working on a small black box to be connected between a PC style keyboard and the 9100 keyboard port to convert the PC scan codes to the required serial.

- What I want to know is how many people would like one and if you would be willing to pay (at a wild guess) $20 for it. I am betting there won't be enough demand to have PC boards made up for them so they will be perf board assembled.
