No it is not connected to anything on my kb101 just a empty pin!!
I understand. This is the pinout of the 2 cables in case it helps. Below DIN numbering is when viewing exposed male pins per this: http://www.hilmanind.com/pinouts/midi.htm fluke din keytronics pcb connector 1 1 red 4 5 yellow 2 2 brown 5 6 clear 3 3 orange shell spade kb101 din keytronics pcb connector 1 6 red 4 2 yellow 2 5 brown 5 1 lt grey 3 n/c shell spade As expected, when the KB-101 is connected to a PC, EA (31) on the the 8031 is high so as you said, this 8031 has a built in ROM. Why not mark it 8051, odd. If I plug the keyboard cable from the Fluke into the KB-101, EA is low with or without a ROM being installed which I was not expecting. The keyboard was still unrecognized. There are a lot of unfilled positions for components on both boards. I imagine it's like the Cherry keyboards (as Paul documented you can convert a Quantel Cherry to an ABI Cherry by swapping passives but the pcb version are the same so it's simple). I'll be curious to adapt mine when you figure it out ;-) I'm curious on the custom keycaps. I know a few places make custom cherry keycaps (no clue if keytronic are the same - I can't believe people collect keyboards just for the sake of it) but they're quite spendy per key and you have a lot of keys here that need relabeling. You may have more luck removing the old legend and finding someone with a laser etching system as you can use toner powder and a laser in the mW range to label the caps, there's a few Youtube video's on people doing it. Good luck. Hope the info helps. _______________________________________________ Techtoolslist mailing list Techtoolslist@flippers.com https://pairlist7.pair.net/mailman/listinfo/techtoolslist FTP site is: ftp://ttl.arcadetech.org/TTL/Test_Equipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/
