PDP 11/70s For Sale

<The only problem with that plan is that with a CPU card (say, a KDJ11-A), <memory and serial lines courtesy of an MXV11-B, and some sort of disk <controller like an RQDX3 and the power draw crowbars the power supply. <At least it has done so on every BA11-VA that I've tried... I've always run out of slots before running out of power. the 11/23 (m8186 dual) plus two MXV11s and a RQDX3 does work if you don't mind using a tu58 to boot it! <Well, they certainly aren't *typical* pdp-11s with a boot console that <can be programmed like any other, or interrupts which work like other <ones, and the console takes lots of code to emulate a VT100, that's for <sure... For the pro350, not so for the PDT11/1xx. <they also have a *64*Hz clock... In RT-11, the clock interrupt service <drops one clock tick out of every 16 -- so it only processes 60 clock <ticks a second... :-) Someday the hardware boys will get it. Allison
