why would you want to have both vampire and aca500 built in at the same time?
Because the 68k ACA500 is 14mhz and the Vampire isn't.
Looks like Kipper is working on an A500/A2000 acceleraror board, so that'll be nice. Might plug directly into the 68000 socket or 500 version externally?
Thing is, I'm using an ACA500 and ACA1221 outside my Phoenix equipped A1000. Hell of a combo (28mhz 020 works great!), but a Vampire solution, with AGA and super speed would be even better.
