Gents,
Can anyone tell me the current prices of the following CPU
chips...
MC68010L12 (ceramic)
MC68010p12 (plastic)
MC68000L16 (ceramic, if such an item exists)
Also, can anyone tell me if a ceramic chip clocked at say +14%
faster than it's design spec states has a reasonable chance of working.
I have heard from SSL (A5000 et al) that if a customer wants to have a
20Mhz crystal put into a A5000 with 68020/16 then that is quite a
feasible request. They state that reliabilty does not suffer you just
gain a higher clocking frequency. They were quite adiment about that
statement !!.

I can't offer much help with chip prices except to say that Digital
probably pays less than $10 for any of these in large quantity.
As for cranking up the clock speed beyond spec -- all chip and any
good hardware board specs contain "margin," that is, designed-in
tolerance for temperature, supply voltage, chip variations, etc. So a
faster clock will work fine in your Amiga at room temperature. But if
it gets too hot, or there are a lot of peripheral cards loading the
bus, or if the power supply outputs change (over the long run), then
your overspeed system will act flaky or die.
Bottom line: it will work, but at your own risk.
Wes
