I have two 8/e machines, one of which has the original panel with
incandescent lamps and one which is a slightly later panel (but the same
type, just a later revision) which has been converted - I believe by DEC
- to use LEDs. I've experimented with different LEDs, and found that
some yellow ones look quite convincing, but as I remember using PDP-8s
with red LEDs back in the day, I've kept the original red ones.
