Problems with simh-V3 and open-sims #8

Open kenrector opened 1 year ago

kenrector commented 1 year ago

James Fehlinger has reported a couple of problems attempting to run this package on simh-V3 and open-simh. Here is what he said, beginning with comments concerning V3.

`So the first clue I had that I'd made the wrong choice was that the '#' comment characters in Rector's sigma.ini file are wrong for SimH v3.12-2, which wants ';'. No big deal. Next up: Simh v3.12-2 couldn't parse the "att mux line=0,2020,line=2021. . ." commands (while it would swallow "att mux 4000"). OK, fine, I'll comment those out for now and do without the privileged terminals and just log in on the nonprivileged lines. Then I booted from the PO tape, started the install, and. . . it went right off the rails.

Next up: "Open" SimH. I used a source repository I'd downloaded on Nov. 28. This got farther -- it could parse the sigma.ini file, install the PO tape to disk, and boot CP-V from disk. But terminals -- not so much. I got the acknowledgements from SimH that a line was connected, but I could not get any response from CP-V on any line (and yes, I know about "!ON 107", "deposit 114a 0", and "telnet> send brk"). Curiously, when I issued a "!ZAP" from the console to shut down the system, then I'd get a squirt of "HI, TCP-V HERE. . . LOGON PLEASE:" messages on a connected serial line.

Last ditch attempt: "SimH SimH", the "troublesome" branch, source repository downloaded as of today. And this worked as expected.`

The latest corrections for the sigma simulator will be available sometime after the release of simh-V3.12-3 in the near future. Watch this issue for an announcement.
