Help Needed From the CNC Guys
Swarfing:
That's it then, 75Plus you've been told now get on with :)
75Plus:
Have a look at this Ebay listing. The box on top is what I think is missing. I am afraid, without it, the software that came with the mill is worthless.

Swarfing:
The setup they show in that add is different from what you have (way to new). I see no connection on your box for any other hardware so we can only go by what we see. Until you fire it up and do a little probing you will not know falling short of documentation to give us a guide.
Swarfing:
Sorry just noticed that you do have the MBC10641 just without the covers on. The full doc has this in the introduction say may need the hardware clock
'The clock input is set to receive
either positive or negative edge clocks with a maximum frequency of 400KHz.'
Might be easier to sell this control unit and replace with new BOB and drivers?
vtsteam:
75Plus was there anything connected internally between Pins 2 and 6 of the three MBC10641s?
I don't think you need a new set of controllers even if you don't have the pulse generator. I think that can probably be supplied by your computer via the parallel port (usually through a parallel port break-out board) to each of your three MBC10641controllers by newer software than Flashcut. Or you could hard-wire it without a break-out board, if you know what you're doing.
I think the "clock" pulse is probably just the step pulse that most CNC software now outputs. And that can be positive going or negative going as set by software and/or your connection to the controller. And you can set the max step rate to suit the 400 kHz requirement in software.
You won't be able to use the old version of Flashcut, but you can probably use TurboCNC (free), Mach (free demo), or LinuxCNC (free). All of these provide the step pulse through the parallel port.
I thought that was what you said earlier Swarfer?
