Hi Paul,

I hope you think about the 7 pin micro-DIN port. the middle "pin" is a
plastic mechanic stuff ...

for this, a short description (from the VCB02 Video Subsystem)...

pinning at the mouse cable :

5 6 7
3   4
1   2

ass:
1 GND,
2 TxD,
3 RxD
4 -12 V
5 +5 V
6 Not Used
7 Device Present (shorted to pin 1)
Shell Protective Ground

running at 4800 Baud. rs 232 .

hope it helps,
emanuel
