Why would you go though the trouble to redact the company/machine name on
the drawings? Whats there to hide?

Nothing to hide, the control is a Protrak. The company name is Southwestern
Industries. It probably is no big deal now, but I decided to hide it
because a box on the corner of the print says not to reproduce it.
Thanks for reply, I will get the computer up and running today.

I did a somewhat similar machine (+-10V amps, encoders) with similar Mesa
hardware with some documentation here:

Getting the machine to move under control should be fairly straightforward.

You'll also want to determine if your servo amps are running in torque mode

If the motors have tachometers then the drives must be working in
velocity mode (and you probably want to leave the tachs fitted and
Yes the motors have tach's. Everything does work now, but upgrade is needed
because of antique control. The encoders are Heds 9000 series with 500 cpr.
Each one has 3 green wires to ground, three red, and 3 black. I will trace,
more clearly mark the wires, and take photos. The x and y encoders

Scott,
Thanks for posting that, I have a 1100M to convert as well... atm I only
have the spindle under LinuxCNC control via modbus to the GS2 VFD. I
hope mine is similar vintage to yours so I can learn from what you did.
Excellent write up.
Thanks

Scott,
I checked out your write up. That is awesome. Ive looked a lot on line for
details on other retrofits. That is one of the best that I have seen. I
will be studying it, and referring back to it. I thank you also.
Joe
Glad I can give back to this incredible community and project in some way.
We've done another retrofit as well, but I'm still working on the
documentation for that.
As you have questions, let me know. If the documentation doesn't make
sense, I'm glad to clarify it.

I'm in over my head, I have an old control I am hoping to be able to
upgrade with Mesa hardware and don't know were to start. The control is Mid
80's 2 1/2 axis, with Glentek brushed DC servos and Glentek amps. I have
schematics and photos. I have learned that the amps output +- 10 volt
