Hi,
See: Hardware Issues and discussion Topic Title : Amiga Technologies A1200 Vs. Commodore

For a list of possible trubs with various Motherboard revisions.
Personally, I have had every type of A1200 Motherboard and never had any of the probs listed.
About Accelerators,
I think it's generally accepted that "The Apollo" range are potentially the worst, allthough again, I have had a few Apollo accelerators for the A1200 and also have an Apollo 030/40 for my A600 Project and they have all worked without trubs.
