Hi All: For your info, I've just completed an update of http://highgate.comm.sfu.ca/pdp8. The following documents were added: PDP-8/i Hardware Maintenance Manual (July, 1969), Volumes I and II; PDP-8/e/f/m Processor Maintenance Manual (January, 1974), Chapters 1 through 4. Thanks to David Gesswein, as usual, for the scanning of this material! Feedback and suggestions for the web site are always appreciated, Kevin --- Kevin McQuiggin VE7ZD mcquiggi(a)sfu.ca
