When I saw that the 2200 stuff was available for free, I figured that the MCP stuff would be as well. Actually I wasn't so interested in MCP, but I liked the stack architecture and programming in NEWP (aside from the all caps syntax). I missed the good old says when the MCP source code told the illicit story of George and Sophia. alan

Back then I could read the panic dump listing, a stack of 3 inches thick paper only containng 36-bit octal words, and find which program (or user) caused EXEC to crash. The joke was ?let?s find the 8?. I did EXEC, Videotex, DMS-1000, and MAPPER. For EXEC and MAPPER I had the SPERRY ?internals? course. I really liked MASM and PLUS. I remember two ERs, ADED$ and SMOQUE$. With the latter I was able to move my print out to the top of the queue ? IIRC, with ADED$ you could assign (and lock) a CPU to your program. A silly mistake in my MASM program ?ate? all three CPUs of the 1100/63. Everything froze, and even on the console in the computer room response was extremely slow. $! had no immediate effect! Those were the days! I think I will try to get 2200 running, but I am afraid I forgot most of it (if not all), it?s been over 20 years. Henk

I doubt it is for hobbyists. I think it is to get people to look at it for the upsell opportunity. And why are people writing ?UniSys?? Speaking as someone who was there during the merger, it is ?Unisys?. alan I doubt it is for hobbyists. I think it is for the upsell opportunity. I sent in my And why are people writing ?UniSys??

I had a chance to play with PLUS while I was a student at U. Wisconsin. It was for an independent study course, using a new EXEC the sysprogs had written to provide access to the batch job queue. Managed to crash the 1108 (or maybe it was the 1110) twice in a row owing to a bug in their EXEC. ;) Later they adapted (or completely rewrote) it, and had the job queue displayed on TV screens down in the basement of the Computer Science building in Madison.
