Heinz,

Using LSX on the 11/03, what did you use for interaction with the outside world? The SLU of the time had only one port I believe, and that would be tied up with the console terminal. Will LSX handle cards with multiple serial ports? Was there a favoured digital or analog I/O board with some form of kernel support?

I do believe that it would be easier to use LSX source code,
but I also know that some folks at universities were able
to modify the source for Mini-UNIX to run on 11/03 in
the mid-70's because of the two, only Mini-UNIX source
code was available to universities.

Team,

I’ve read thru the FAQ and other sources regarding compatibility of Research and other flavours on the PDP-11. I have two physical machines, an 11/03 and an 11/23+. I’m choosing which version to use on each machine.

Is LSX the only option on the 11/03, or could I run V6 or Mini-Unix with more RAM?

From the FAQ, it says V7 would support 11/23 with kernel recompilation, I assume includes 11/23+. I see 2.11BSD would also run on a ‘23 (and + I guess) with 1MB or more of RAM, so that would be preferred. I suppose 2.11 would be preferable.

I also have found another 11/23+ system from a seller here in China. There’s the system, and a VT100, and a hard drive I can’t identify. Here’s a photo, does anyone know what it is? I may bid for it...
