    No I don't think 20MB modules exist. There are revisions to some modules
though. I had three MS02-AA's and I think it was an MS02-BA. They are both
8MB modules, but the AA's have like 88 chips or so on them and the BA has
like 12. I don't think they made a revised CA (32MB module), I think that's
as high as they go. You might also have to take into consideration that the
AA's at least are interleaved parity memory modules, so you have parity for
each bank and 2x the total number for interleave. IIRC anway, I could be
totally wrong.
