- -- When I did the 1230XA design, I knew that 30 pin modules were on the
- way out... for the Mac as well as the PC. It was important that people
- be able to upgrade their memory over time and not have to rely on some
- kind of *oddball* standard. My examples in the market at the time were
- GVP, with their *own standard* of how to do the memory. I actually was
- in a verbal dispute with a GVPer about what SIMMs to use... Time has
- shown my position of *use the standard SIMM* correct. Yes, just one
- SIMM too... Some of the 72 pin SIMMs are very long & wouldn't fit....
- I knew people would be *trading up*.

- -- sysinfo measures speed *bogusly*. A better measure (and certainly
- more accurate) is AIBB.
