David,

I have a Denford Triac mill, which is probably not too different. I
have removed all the original electronics and electrics, and
installed Geckos, VFD drive interfaced to TurboCNC, and added a
fourth axis. (circuitry in the files section of the TurboCNC group on
Yahoo). I have retained the original stepper motors, limit switches,
home sensors, oiler etc.

I choose TurboCNC having initially intended to use EMC, but spent
best part of a year dallying due to not really being happy with a Unix
environment. THe TurboCNC source code is available, so I was easily
able to integrate my VFD interface and other oddities.

(The original Denford electronics had a serial link presented on a
Din socket using a simple 3 wire interface.)

I am part way through converting a Denford ORAC lathe, again using
TurboCNC - got the thing moving under PC control last night, but not
yet built the electronics for automatic spindle speed control
