Their entry into the PC business certainly was ill-conceived.

That was part of DEC's problem.  The Rainbows weren't completely
compatible with MSDOS software. Then they tried to lock everyone into
buying their diskettes with a proprietary format. Add to that the single-
sided siamesed drives and other quirks they were too far from what the
market expected by then.

Alive and kicking. A few years ago I interviewed a fairly young guy and I
was surprised when he had PLC programming on his resume. I'd been away
from industrial applications for over 20 years and thought they would have
faded away in the '90s.

Relay logic was sort of fun. You were building state machines with relays,
Eagle Signal electro-mechanical timers, limit switches, and so forth. I
never did it but even more fascinating were some of the complex machines
that were all cams, levers, gears, and springs except for the drive
motor.

With all its sophistication it wasn't protected against an attempt to
divide by zero. It would churn away until you pulled the plug and put it
out of its misery.
