"Computer Grade Capacitor" might possibly refer to the low value of internal
series resistance and inductance which are important parameters in switching
regulator power supplies.

I keep seeing caps described as "computer grade" but a search for a

What does this mean? As the vast majority of computers are owned by the
masses, one could assume it means sleazy consumer quality. Or it could
mean the kind of computer that prevents ICBM's from being accidentally
launched.

Which is it?

Digging out the 1968 Newark catalog, on page 332 are the Mallory CG
series of big can capacitors in a section titled "Computer Grade
Electrolytic Capacitors". ie -10+75% tolerance, -40/+85 deg C temp.
$10 was a lot for a capacitor in 1968.
