In addition to the well known SX-1, SX32, and ProModule, there were also a few stand-alone disk drive-only units available for the CD32. Plugged straight into the expansion connector.
Yes, I think you mean the
CD32fWSI expansion. I took a
shot of the PCB with my crappy webcam. I'll take a better shot as soon as I get my hands on a digital camera :-D
