Cross your fingers that the board still have the 030 onboard, if it's missing you're also likely to be missing the 50Mhz oscillator at U104 (the motherboard takes this signal from the 3640 CPU card). The result is that it won't work with asynchronous CPU boards since you won't get the correct clock when changing J100/J104 to INT... might just be to add this oscillator to the motherboard however since it's low cost there isn't a socket for it so you have to get out your soldering tools.
