When I was *much* younger, I used to run into them occasionally.
The BED coding made no practical sense to me. DEB would have made
more sense, allowing one to recognize the multiplier with a glance,
instead of grabbing the resistor and maniuplating it to see if what
you have is a 470 or 47K ohm reisstor. When these things were
soldered tightly to mounting strips in military equipment, it could
get to be downright frustrating.
Another one to confuse-a-boss would be 6-dot mica capacitor color
code (one could find these on 1960's computer equipment). I probably
still have a few of these in operation.
