Roms for A1200?

Lips2k8 · 09 February 2009, 20:40

I was wondering if I could use Amiga CD32 rom chips or Amiga 4000 rom chips in my Amiga 1200?

Not as far as i know, the a500/600/2000's are interchangeable but no others.

CD32 have the proprietary boot CD libraries on ROM. No other Amiga have it (except CDTV who have another kind of the same).

A1200 have only IDE and PCMCIA card.resource/device (no use in other Amigas).

A4000 have Zorro arbiter and no PCMCIA...

The scsi.device driver on the A4000 KS is customised for the A4000's differently mapped IDE interface.

AFAIR CD32 only has 1x16-bit ROM chip whereas A1200 and A4000 have 2x16-bit ROM chips.

A4000 ROM requires RAMSEY chip. (no RAMSEY = infinite loop)

Hmmm.. THAT is interesting to know...

It does some kind of memory test (checks if page mode can be enabled I think) and it freezes because (missing) RAMSEY mode register never changes.
