PDP-6 Home Page


The PDP-6 is a 36 bit computer architecture developed by Digital Equipment Corporation in about 1963. It was constructed from system modules, an early form of digital logic based on germanium transistors. The logic was powered by -15 volt supplies, with a +10 volt bias. Logic levels were 0 and -3 volts.

Logic pulses, delay lines, and pulse transformers were widely used to construct asynchronous logic networks.
