[HECnet] DN60 etc. --> Anf10 family based?

Thomas, If I recall correctly it is Anf10 related and has it's own runtime and Chk11 for initial testing of hardware. Thus it had to fit in 28 kW; no relations to Rsx11 or even RT11. The code pieces then should be *.P11 etc. Reindert -----Original Message----- From: Thomas DeBellis [mailto:tommytimesharing@gmail.com] Sent: Monday, 31 January, 2022 21:22 To: hecnet(a)lists.dfupdate.se Subject: [HECnet] Re: native Dup sync line revisited --> revisited Dup test on pdp11 --> problem solved: Simh KG11 emulation probably defective Then we are probably talking apples and pineapples. The product that I'm talking about is exclusively for the 36 bit line, requiring a DTE to get the data to the PDP-10. I think it also needed a KMC to do some offloading, so the 11/34 could keep up, but I wouldn't swear to it. There's code for a KMC, anyway. The software appears to be a complete embedded design: there are no users, no file system, minimum memory management and no task preemption. Thus, I don't believe it has any code basis in either RSX or RSTS. I wouldn't be surprised if part of it got lifted from RT-11, but I don't have an informed opinion on that. The DN60/DN65 spoke 2780, 3780 and HASP. The first two are remote job entry (RJE) 'workstations' that had card readers and line printers (no terminals). HASP is a variant that IBM did not develop, yet adopted. I believe it was wizzy because it allowed multiple concurrent streams. The job of IBMSPL was to fool the remote IBM host that a card deck was being submitted by a timesharing user and to take the resulting print output and to get it to wherever the right place was (printer, file, etc.) I don't recall a 3271, I guess you mean those green screen terminals? What a beast... I do recall using 3270, 3276 and the like when I was hacking the bisync drivers on VM to talk to IBMSPL. There was a product that you could run on Tops-20 to show up as a 3270 on an IBM box, provided the target spoke TCP/IP. I can't remember the name, but it was based on TELNET negotiating some additional options. It's a lot of work; a 3270 is not like anything you ever heard of in ÅSCII land. A number of us swore that IBMSPL was the only reasonable way to use an IBM mainframe as the 3270 was a half-duplex terminal that was all to ready to lock the keyboard if you even thought of typing ahead. The more modern emulators don't lock like that, but you are still effectively in a late 1960's half duplex paradigm. Still. Today. Really.
