[Boatanchors] Diode color coding

[J. Forster]

Most likely yes. In the early days, diodes were not marked as consistently as resistors. By the '60s, they were pretty good about it on the glass ones anyway. IN457 were almost always
Yellow-Green-Violet. I remember 1N34s with white bodies  and two color bands. By the '80s they were printing numbers on them.

BUT, computer makers often 'house numbered' diodes, so it's not 100%.
