A500, which ROM 1.3 or 2.0x?

Cool. How about the 3.1 ROM? (I'm guessing it's worse)

It's actually better than 2.0x but worse than 1.3.

How much RAM does an A600 have I have heard 2MB and I've heard 1MB?

1MB per default, another 1MB in the trapdoor, more megabytes on an accelerator (nice), and up to 4MB in the PCMCIA slot (not good, don't even consider it :-)

Are you sure it's the same speed as CHIP RAM? I'm under the impression that the PCMCIA bus is slower regardless.
