- The chart I had did not describe combinations with 8MB or 16MB simms,
- which were not readily available at its printing. But I understand
- that one can take a IIci to at least 64MB and maybe 128MB (4x8 by 2,
- or 16x4 by 2???). Don't quote me on the 128MB though, that may require
- a newer machine (=quadra).
