Well, that's the beauty of an FPGA - you don't *need* a video card, for
example - the video can be driven directly from the FPGA. As long as you
choose a suitable DAC, you can design in anywhere from 8 to 16M colours.
Ditto for mass storage - you just need the appropriate connectors.
That's the idea with the Coco "personality" adapter module - it's really not
much more than a physical interface board, with a bit of analogue circuitry
