- David,
-
- You can add RAM in the 32-bit address space; you have to use a RAM
- add-on that plugs into the expansion connector on the 2630. The 4MB
- that plugs directly onto the 2630 goes in regular Zorro II space; if
- you add an add-on RAM board to the 2630 card (currently DKB is the
- only company that makes one), you can go up to something like 64MB (or
- was it 118MB?).
-
- Many third-party accelerators allow >8MB of RAM to be added right on
- the 030 board. The limitation above applies only to the 2630.
