SPX, in fact, is the "accelerated" colour card (GPX is the standard but slower 
version).

The board is a SCSI interface for a standard 3.5" floppy drive. Just plug it in
and it should show up using a console SHOW DEVICE.

To use a TK50 it would have to be in an external box. A TZ30 (uses the same 
cartridges) might fit into the box but I've never seen suitable mounting 
hardware to do that. (Note that the VS3100-76 is slightly different to the 
previous VS3100-30 and -38, and mounting kits for those won't work here).

TK50-K cartridges hold approx 95MB each.
