- a 21MHz 020 could maybe squeze speed near to 21/14 ratio from chipmem.
- a read is currently done in 12 cycles(14mhz) and would most likely
- go 8 cycles(14Mhz), what would again be 12 cycles (21Mhz).
-
- but above 21MHz... no way.
- I hope the 030 will be non-EC and at least 40MHz.
- but without fastmem... argh.
