Most chips in commercial products are rated to run from 0 degree C to 70
degree C, meaning 32 F to 170-or-so F. "Automotive" or "industrial"
chips have wider range (-25 to 85 C -ish, but varies from company to
company and depending on the label). Military chips go from -55 to
+125 (!!!) C. Try converting these to Farenheit yourselves.
Well, the Kaypro "cold" problem probably WAS mechanical - if it was electrical
the computer probably wasn't functioning at all. Contrary to the numbers
given by the companies in the data sheets, most chips can endure very high
and low tempraratures beyond the stated limits (remember the SS-DD disks
you could use the both sides on, in the good-old-apple days?), but this
is difficult to be true with mechanical things (I have run a computer
with *7* volts applied to the VDD once, and it did fine. I stopped very
fast, though. Mechanical things may not break down as easily under stress,
but they sure as hell malfunction.)
Is this a debate topic? Less make it private, ok?
