PROMs? When I was young, all we had were diode arrays!! ;)
When I was young, (semiconductor) diodes came in white ceramic
packages with metal endcaps and were usually germanium. No, the PROM
was for a production design, ca. 1983. It was expensive
(particularly if you goofed), but it eliminated quite a few
packages.
The earliest diodes I remember were packaged in glass. Not the
standard glass packages that we see 1N34s and similar diodes packaged
in, but about 50% longer and curved, so they bulge a bit in the middle.
I have no idea of what type they were, but they were germanium.
