Looking for a TURBOchannel Extender Cable

I have finally fixed the PSU of my TURBOchannel Extender (https://robs-old-computers.com/2018/09/23/h7826-power-supply-repaired/). Which means that now I would like to connect it to my DECstation 5000/240. I need the relevant extender cable, which I believe to be a BC12N or a 17-03335-01. I asked o

Re: HP CPU32 Emulation Adapter

hi what have you used as ICE? or, have you only used a software debugger? and why not the motorola monitor? I see you have developed your own monitor why? p.s. I have opened this website(1), it offers space for a sort of mini-Bazar, but there is also space for junks of files. I am collecting and

Re: looking for out-of-print computer book

I wonder if the book was announced and never released. It's pretty rare when something that new doesn't show up anywhere. Very likely as the LC has no such entry (and they receive all titles published in the US). The computer industry is not the sole inventor of "vaporware".

SPACEWAR! Switch Boxes for a PDP-12

Visitors to the RICM like to play SPACEWAR! in the PDP-12. Unfortunately using the console switches is uncomfortable, not intuitive, and is tough on the switches. We would like to recreate the switch boxes used on the PDP-1 to make playing a better experience. We modified the source
