to find the most information on the Scorbot's.

Don't get ER4PC robot unless you can also find an ER4U Scorpower (the
control box has it's own name) and ditch the PC Scorpower. The robot
itself is exactly the same, will work with USB control box. The PC servo
card that PC version needs is a real PITA. Intelitek still sells it for
$600 (and I believe it's refurbished) but it requires a computer with full
length AT ISA bus - I haven't seen a monster like this in 15 years, will
be a whole project in and of itself just to find a PC to stick it into.

I was thinking of using the 4pc controller as an amplifier box and using
LinuxCNC as the controller to provide PWM to the 4pc controller. I have
used the Mesa anything I/O boards with LinuxCNC and it has encoder inputs
and PWM outputs. I don't know if the 4PC control takes pwm plus direction
or exactly what. I thought I could get the Mesa board to replace the PC
board for the ER4PC controller, I found the 62 pin high density Sub-D
connectors at Digi-Key.

Thanks for the info and links, I'll see if I can send ascii commands through
RS-232 to the controller.
