We are trying to revive a PDP 8L, and wonder if anyone can
advise us of the equivalent of the DEC1008 transistor, npn
germanium, and also where we might track down any of the following boards:
G228, G826, G624, G221.
Thanks

Hmm. Everything I've looked up about these says the DEC1008 is
a rebadged MM1008, which in turn is similar to the 2N3444. The
Motorola MM1008 and the 2N3444 are silicon NPN, not germanium.
You can buy 2N3444 here:

and also where we might track down any of the
following boards:
G228, G826, G624, G221.
I see them on eBay from time to time. G624 -- item #270937110031,
for example.
Hope that helps!

A chap here in sweden is doing an extraordinary restoration of a rusty
old 8/L. He also contemplated using 2N3444 and one or two other
variants. I'll find out what i actually used in the end. (He also
confirms that DEC1008 are the same ase MM1008)
