Well the card was never finished ..... unless you fancy coupling a G3 with 2MB chip-mem (and I mean only chip-mem) that is.
So you'd need more work to finish the design, hunt down parts long out of production make those parts ROHS-compatible by pure magic, write SW for it .....
Honestly I sometimes started to wonder how much of an FGPA one would need to couple an Freescale MPC5200B (or similar) to the 680x0-bus. Sure one would still need to write SW, but getting the pur PPC-side of the HW up and running should be pretty much stressfree (maybe even by licencing the EFIKA-design).
Much better approach then trying to regreate something that did(n't) make it to market 10 years ago.
