Yeah, I noticed there were a few interesting cards like the PC drive card (which I will test to see if it is remotely compatible with IBM's external floppy drive with the same connector) in the pile. There is also a video card for the Radius Pivot.

The Diimo card appears to be a 50mhz 030 upgrade with cache (that sounds a bit weird in terms of speed).

I'm still googling and I'm not finding anything in terms of what cards go with others or with those boxes yet. Is there anyone here with some experience on hardware like this?
