1) Unfortunately the Mach I isn't compatible with the Mach II circuit boards, and there not available anymore since nVentiv went bust.
2) The Mach II has some sort of power supply yes. Basically its control board is its motherboard if you can picture that, which has high power relays on. When the power switch is pushed the board sees this and switches the relays over to supply power to the compressor. Thats the simple working of it, it's much more complicated than that but I havn't figured much more out yet.
The Mach I does the same only using the main mobo in the system as it's realy if you will, and uses simple technology to simulate the reset button being held down until the right temps are met, and releases reset. This is where problems arrise with boards that don't hold reset and why nVentiv came up with a new design for the controllers.
The plug that goes into the Mach unit is the power for the compressor and Mach unit. Nothing is actually powered by the PSU in the PC on the Mach units unlike Vapo PE, and XE's, the molex is only used to let the control board know that the PC is powering up and not to shut down again. Uses some sort of PIC Microcontroller in it, with a built in program running enabling all of this in the Mach II systems. The Mach I was the same sort of idea only much simpler.
At absalute zerro all moleculer motion stops, and you can hear a Canadian say: "Think I may need a coat!"
