[sdiy] Weird old logic chips & transistors

[harrybissell]

Most of your haul is RTL  (two generations pre-TTL)

I'm really depressed that your GRANDFATHER had this stuff... I makes
me feel very, very old. Even older than I did today as I built a test fixture
for work on old-school barrier strips (phenolic with lugs on it... :^).

My first fuzzbox used RTL cans... it was from a 1970 article in Popular
Electronic called "Timbre Gate" by Craig Anderton.
