Hi Chaz,

Well, looks like a good buy with some nice extras! You don't need power to open the latch, there is a discrete hole somewhere round the back where you can insert a thin rod to activate it. I can't remember exactly where and not at home at the moment to look. I think I probably looked up the latch on the web to find out about it. If I remember I'll have a look at home this evening.

As this mill uses AC servos rather than steppers I suggest that you also join and post an enquiry at the Denford site http://www.denfordata.com. They have the wiring diagrams there and you should be able to get information on the servo drives. If the problem is the PC OS not booting I'd suggest the first place to start is there, and try to see if you can use the mill as-is, if necessary with a new PC.
