Gents,
General Tree Info: The Tree controller is a very strange beast
hardware wise. I looked it over and only saw TTL chips. It had Treat
functionality including being able to learn and replay. The encoders
are standard BEI 5 volt quadrature, 1000 pulse/revolution. The servos
are 90 volt 4 brush DC (never get warm...). Ball screws everywhere, 0
backlash, turcite box ways. Existing servo amps are servo dynamics +-
10 volt differential with tach feedback and if my experience is a
guide probably good. Spindle contol on mine was also a standard
(big!) servo drive.

The $40 WWW.USDIGITAL.COM encoders are almost plug and play. Don't
ask how I know...
