[GreenKeys] Happy birthday, PDP-8!

Speaking for myself, a PDP8 provided my first exposure to a Teletype 
product, namely the ASR33 that was the main I/O terminal on said 
computer, thus lighting the fire of interest in all things Teletype when 
I was but a middle-schooler in the late 70s.

So, perhaps the computer isn't on topic, but its attached terminal 
certainly is!

FWIW, YMMV, etc.

73,

Doug, KA2WFT
