Fred,

SOME is not MOST ;). Yeah some will but if you were to pick up a generic
8bit FDC off of eBay chances are it won't

Agreed, as I said I would have liked to see more of the CompatiCard IV
functionality replicated. Or if they wanted to go above and beyond a 50 pin
internal header (for 8") and/or an edge connector (for 5 1/4") would also be
nice.... OR built in FDADAP functionality? How about better copying prowess
(e.g. put Copy II PC circuitry on the same FDC)? The deluxe chip might be
hard to replicate but the earlier TTL one should be doable)...
