on 02026-05-26the VT78 was a #PDP-8 (2.2MHz Intersil 6100) crammed into a #VT52, shipped in 01977; it was succeeded by the DECmate and the DECmate II.

on 02023-07-02A compiler for the "B" programming language from which #C grew, written in modern times to be compatible with the original bytecode interpreter, with backends for #PDP-8 (unfinished), #PDP-11, amd64, #RISC-V (64), and #MIPS (32); by the retrocomputerist #aap from Berlin, who has squoze.net. #history

on 02020-06-20The “straight 8” DTL #PDP-8 only contained 1409 transistors, but 10148 diodes, 5615 resistors, and 1674 capacitors. Warren Young describes the PDP-8's memory model as “complicated”; Douglas Jones explains the “diode-capacitor-diode” gates used. #retrocomputing
