As I said before, I run a WarpEngine, CV64, and MultiFace
serial cards in my A3000D. I haven't done the Int2 hack or
upgraded any chips (all standard origonal chips).
I bought this A3k new in 1990 or 91 ( can't remember for
sure) and I haven't had ANY problems.
Oh ... I did upgrade to 3.1 roms.
All those chip upgrads and hacks mentioned in the other
posts don't seem to be necessary in my A3k :-D.
Also .. with WHDLoad and a RTG GFX card (if I understand
correctly) the AGA chip set means nothing.
