"Prior to that they were all bipolar ECL and watercooled."
PDP-10's were ECL based machines and if I am not mistaken the failed VAX
9000 series (circa 1991) was too and that was the end of ECL (that I am
aware of).
"First mainstream successful CMOS microprocessor I'm aware of was the RCA
"COSMAC" 1801(?), circa 1975. "
Does that bring back memories! I built a COSMAC 1802 machine (I think 1802
is the correct model number) for a logic class straight out of a Popular
Science article. I had to ask my dad for $40.00 to buy the chip IIRC.
If you have a stash of old magazines, keep an eye out for a
copy of Electronics dated April 19 1965. The Intel corporation
wants a copy bad - $10,000 reward!
That's a good price for an old magazine...
