- 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
