Or find out if the RAM card interface has enough of the databus to contain a ROM/RAM card. Then you can run the appropriate jumper wires. IT would be universal at that point. 

The Classic II, the RAM slot is actually a ROM expansion slot. So it would just be direct plug/play. The Classic 1, youll probably need a couple jumper wires.

It actually isn't a RAM slot on the Classic II, it was always meant for an FPU/ROM card, that's why there are spots for RAM SIMMs on the main board. Although it looks similar to the RAM card interface of the Classic I it was never meant to serve the same purpose as a RAM expansion point.
