Here is the pinout on the Keyboard, Don't know if the scancodes are
anywhere near the same, but this came from the IBM Tech Ref Vol I, page 9-23
-------------
| | pin 1 = + 5 Volts
| 5 3 1 | pin 2 = Data
-- -- pin 3 = Speaker
| 6 4 2 | pin 4 = Speaker
| | pin 5 = Ground
--------- pin 6 = Clock
The book has a big chart of scan codes and key function output codes,
larger that I want to post and type, but I am not sure how they compare to
a PC keyboard, if at all.
Locator (mouse or tablet)
-------------
| | pin 1 = Ground
| 5 3 1 | pin 2 = Transmit
-- -- pin 3 = + 12 Vdc
| 6 4 2 | pin 4 = - 12 Vdc
| | pin 5 = + 5 Vdc
--------- pin 6 = Receive
Programmable in 25,50, 100, 200 counts per inch default = 100
Protocol RS232C 9600 Baud async Fullduplex stopbit = 1, odd parity
at reset sends a special 4 byte report sequence 0xFF080000
Stream mode, has a loopback mode, report function stream is:
Byte 1 always = 0x0B
Byte 2 bit 0 1 = right button pressed
bit 1 always 0
bit 2 1 = left button pressed
bit 3,4 always = 00
bit 5 X data sign 1 = negative
bit 6 Y data sign 1 = negative
bit 7 always 0
Byte 3 bits 0-6 X data bit 6=LSB
bit 7 always 0
Byte 4 bits 0-6 Y data bit 6=LSB
bit 7 always 0
How this fits a PC mouse I don't know, but every bit of info can
help when putting things back together.
This info came from an IBM BOOK SA23-2610-0 IBM RT PC Hardware Tech. Ref.
Cheers.. and good luck
