I have a (very dim) recollection that the 3083 at SFU in 1991 had a whopping 24 MB of memory - but someone else from SFU can correct me if I'm hallucinating again. ;-)

It's fun to run MTS on a modern machine and give it 128 MB of memory (because I can!) and never have to page. Even when I had it on a Raspberry Pi 1. :-) For serial devices - if someone can generate a system with a 2703, async (and bisync?), would it be possible to get 'physical' async and bisync to work? Or to emulate? I used to have an ITEL/Dura Selectric terminal which would have been fun to watch on MTS again, but even it got consigned to the scrap heap years ago. I do have a couple of old PCs with serial terminal emulators on them, including a multi-window VT100 emulator that I wrote in Turbo Pascal when working on the NIMs. For bisync, 2780 protocol is trivial, and would be easy to emulate - if it isn't already out there in the form that you want. It would probably take a day to make work. 3780 is a little more complex, but still easy. 2703 provided very basic I/O even to video terminals. You could get graphics on a Tektronix 40xx screen, but there was no full screen editing or such. For the UBCnet-style networking you would need a Node and a NIM (hardware or emulated) to get async full-screen terminal support - but x3270 exists now and works. I had thought of running a Node and a NIM in a PDP11 emulator as a masochistical exercise - just to see if it works- but there would still be work in emulating something like an Auscom channel interface in the PDP11 emulator as well, and a way to interface it to Hercules. I have been using some crude scripts'n'tricks to get printouts and file transfers on D6.0 using the bare reader/printer/punch devices since MTS was released for Hercules - until 'real' networking is eventually available. - Richard, VE7CVS On 1/26/24 9:53 PM, Mike Alexander wrote:
We never had anywhere near 32 MB on an MTS machine.? I think the biggest one might have been 8 MB and we supported up to 300 users on that machine (although it was sometimes a struggle).? Whether you would get paging on a 32 MB machine depends, of course, on what people are doing.? I can bog down the paging system all by myself if I want to.? However a few people doing "normal" things won't put a significant paging load on the machine. |
