I have a related question I have been wondering about for a while: which program cards are compatible to the 208r v2? Do I need the Roman cards or do the BUSA cards work as well?

The Roman cards I have look different than the ones in the Easel
Weasel manual.

Roman's cards are clones of the original 70s ones, the upper part is meant for extra circuits thanks to the +/-15V rails and ground.

The card shown in the manual is an earliest revision without the +/-15V and ground connections, for an Easel prototype fitted with a shorter connector. Allen Strange had obviously this one when he wrote the manual.

The BEMI cards don't have the upper part for extra circuit either but the pinout is compatible.

I'm not a synths dealer and I'm not aware of an inexpensive Synthi secret market, please don't ask me if I know one for sale.
