I have a 190VMC with toolchanger...
I might be tempted to sell the toolchanger for the right price... I don't have the original boards any more as mine is converter to Mach3 (including the toolchanger)
I have the wiring diagram for the 190 in JPG format.
I have a paper copy of the Student manual
I have electronic (PDF) copies of the user and programming manual

If there is anything you want, Send me a mail and I'll send you the docs..

Thanks
Simon
