I recently purchased a very clean, well maintained, Bridgeport R2E4 with
Boss 9 controls. (30 lb. DC servo motors)

One problem, when I throw the switch I get no CRT activity and every light
on the control panel comes on and stays on. I have been through the trouble
shooting section several time and everything seems to check out ok on the
power supply side of things.

Well, you might try reseating any socketed chips on the computer board.
There should be a board in there with a really big purple chip on it,
that's the 68000 CPU. There almost certainly will be some EPROMS (24 or
28-pin chips with paper labels on them) in sockets. Just lift up each
end of the chip with a small screwdriver, and then push it back in.
Do this with any other chips in sockets, too. If that doesn't work,
then you might not want to spend too much more time on it.

My question is does anyone have some suggestions as to what could be problem
off the top of thier head. Also, I realize these controls are nearly 20 yrs
old. Can anyone steer me in the direction of a PC based controller that I
can install and use a laptop to control. Preferably I would like to
accomplish this for under $2K.


What servo amps does it have? Are they the NC-400 model?
