I have one of these but did not know what model it was. It appears you have two drive cabinets. Mine had a roll around desk with some controls on it also. You can hook Mach3 to it.

In your picture with the open door the board to the left with the little blue wires leaving it, these are the wires to control X,Y & Z axis. The difference between this and the BOSS machines are:
1 The output transistors are on a plug in board.
2 It runs on 120vac single phase (high current riquirement)
My breakout board works great with these.
