- As other will undoubtedly point out, the 030 on the card has a 32-bit
- address space, so you can put RAM in places outside the 16MBs
- addressable by the EC020.
-
- Also, I believe that you can use the upper 4MB that's "reserved for
- PCMCIA use" for autoconfig RAM; you just can't plug a PCMCIA card in
- at the same time. Not sure what happens if you try to do both.
