Re: Gemini 80-Bus System
Oh, I know where most of my PDP11s are -- the large Unibus ones in rack cabinets, etc. This was just a little 2U high box with an LSI11 CPU board, RAM, and a couple of interfaces in it. Not actually the smallest PDP11 I own, but close.
From memory, my Gemini contains a CPU board, IVC board, and floppy/SASI board. The latter goes to some bridge board thing (I want to say Adaptec, but it may be Xebec or somebody else) and to an ST412-interfaced hard disk. One of the ports on the CPU board goes to that network interface I mentioned.
I also have (and have put with the machine!) the original keyboard and cable. Also what I believe was the video monitor used with it originally. Just a composite video monochrome thing of course.
Interestingly, I have a Torch-branded lightpen for the BBC micro. This consists of an inteface that plugs into the Beeb's analogue socket (DA15) and a light pen that plugs into the interface using a 5 pin DIN connector. That DIN connector is the right pinout to plug into the IVC lightpen socket.
