OK, I was wrong. The motors are not Glentek they are Milltronics brushed DC servo made in London and identical to my SEM motors, both have pulse coders.
The drives are Glentek GA3703.
The motion boards or whatever are full size boards and are mounted the the 386SX or DX motherboard, they have the tach, Arm, analog inputs.
Are these boards just 1994 versions of the DSPMC and would they compatible to plug into a new computer, knowing my luck, not.
I have been around Fanuc for years and can't get my head around these motion boards, but I am not giving up.
I had no success with the DSPMC and the Fanuc AC drives and motors, that PID tuning is nuts, I am waiting to get my 3 in 1 Fanuc AC drive unit back, they say it's all smoke and mirrors, mine was just smoke and a little fire.
