Some people have asked us if they can use ACA together with
Vampire500. This will not work.

WARNING : Do not do this!

Any harm done to your AMIGA or Vampire caused by doing this is not covered by warranty.

Why would someone try to have two accel. cards?

Because they already have the ACA, felt unsatisfied and wanted a fast card instead and fell for the "lack of compatibility" FUD.

Hmmm, I think both cards do the ROM replacement thing, and have IDE controllers - probably at the same address space. Hopefully it’ll just end up with a “logic brain freeze” with both cards just fighting to be processor bus master - rather than anything getting 12volts on a data line.
If i figure this, the vampire will be the primary cpu, then the 68010 on the aca500 initiates a cpu bus master request and it probably goes downhill from there :D

I can see a reason; but it’s a slim reason if you didn’t know any better - externally accessible cf slots with the case closed.

Anyway all of this is just conjecture from me, as I have no experience with an aca500, just what I’ve read up on it.

A bump the thread as “please don’t try this at home” :)
