It's a Harrison Trainer manual/CNC 280. It previously had a conversion from it's original dead controls to Microkinetics stuff and now I'm going to LinuxCNC with the MESA 5i25/7i76 set, retaining the MK stepper drives since they're fine. I'm doing it as a strictly CNC conversion since I have other manual lathes. I installed a new Hitachi VFD to drive the spindle which is working nicely.

I just bought a CNC lathe to retrofit and I plan to use mesa cards again. Good luck with your build.
