I think it's suppose to COME OUT in '92... the chip it self... there were no mention when systems built around would come out. 486 aren't even running 50Mhz, yet without the ICE CAP device which also has a 5.2V voltage regulator. A major draw back to a 100Mhz CPUs... finding memory fast enough to keep up with it... I'm pretty sure you need something close to 1ns maybe faster just for main memory... well at least for the cache... with wait states... There is some slight good news for the 65816 and CMOS chips... IBM has comeup with a process to boost CMOS performance by placing a insulator layer under the CMOS... it was mentioned in a recent BYTE article. Speed improvements were 3 times faster and just silicon CMOS chips... the process involves growing the silicon on top of the insulator and then etching the circuit. It looks very promising... I think if similar types of processes done for the 65816 we could see some vast improvements... most other CPUs ddon't use CMOS so maybe they won't benefit as much. Another thing is the the insulator also reduces power comsumption... and CMOS is pretty low power drawing type of circuits as it is... more as they come availible. whitewolf@gnh-starport!info-apple
