If you look on Ebay you can usually find these types of manuals on CD Rom, and there are a few people who can answer good technical service questions. However, most people (myself included) consider the original controls to be obsolete junk at this point. I ripped everything off of the junkyard Boss3 I bought and installed Gecko drivers for the original steppers for far less money than I'm sure it would have cost to bring the original circuits back to life.

That's why I need schematics.. I think I'll use orginal stepmotor boards and Mach 3
to control this. I'm so poor, I can't even think gecko's or similar systems..
This machine cost me only 1000 € ( there's missing some variators parts.. ).

One of the biggest costs is the power supply. There are some people on the net who have been successful at modifying the stock power supply to feed Geckos or other drives. If you could do this, and assuming you have the appropriate power to run the spindle motor, all you would need are 3 drives. This would cost you maybe $400 (I'm guessing European shipping costs), which isn't cheap but you could sell off some of the old control boards and recoup part of your costs. Good luck!

I get schematics ( thanks Darek! ), only what missing was computer part, thats
not important to me, but if somebody have, i'd like to see those schematics.
Old computer are always very interesting...
And if anyone have maintance manual? Only parts numbers to
milling head needed..

But I have another question: where I can lift this mill? I'm bringing
machine to my home next week, and I borrow hiab truck ( I don't know
what is called elsewhere, but it's truck with hydraylic lift arm..).
With a chain around milling heads arm ( or what is it called? )?

Hiab will work fine, just don't use a chain. I understand your english issue but I just wanted to make sure. Use a sling, chain would / could score critical surfaces.
Make sure it is rated for the weight of the machine.

Yes, I got machine in my home safely. It look little bit suspicion
to lift, only four about M10 bolts between arm and body.
Now starts retrofitting... Thanks lot to everyone!
