I don't have an RX01, but I do have an RX11 interface and an emulator.
I have the emulator interface that was given to me by Bruce Ray. This has a four pin Molex power connect like a floppy disk drive.
This adapter will connect it to the 11/40 power distribution panel.
This will be +15V from the 11/40.
