Oy! This has some nice 20W + 40W resistors on it. So I'm guessing this requires
a decent power supply.

BTW, nice unit, decent weight.

6 wire motor, guessing it's a stepper motor.
40 pin IDE, not sure of the interface but the main CPU is an 8748
CPU (EPROM based CPU). I'll figure out the input/output later.

Now I'm really interested in your project. Did you bypass the 8748 and
drop the Arduino in it's place?

I think this is tonight's CDL teardown and photograph project.
