At Rose-Hulman they had a PDP-11/70 running RSTS that they had modified to have more than 128 terminals connected to. It's my understanding that it had 128K of RAM, and 144 terminals at one point circa 1982.
- musicale 4y agoKind of amazing the sort of functionality that old multiuser/timesharing systems were able to deliver. 128K (words, presumably) of RAM seems a bit low though for 128+ users.
- mikewarot 4y agoYou typically had a few run time systems, like BASIC+, TECO, and others running (Compilers), and the Batch Queue, then a user with 1 file open and an edit buffer. Yeah, it really was amazing how they pulled it off. Given my current machine with 32 Gigs of RAM, I could give 32,000 users a megabyte each. Moore's law was a wild ride.
- hulitu 4y agoWhen the resources were limited, it is amazing what people could do with those systems. Nowadays, it is amazing that calc.exe needs 2 seconds to start and sharing files between systems has not improved much from that era. Oh, and 30 years ago a blinking cursor was not such a challenge as it is today.
- aap_ 4y agoI made an 11/40 to hook up to the PiDP-11 panel: https://github.com/aap/fpga11 https://github.com/aap/fpga11 Unfortunately no disk or anything (that's always the hard part) and also it's not an 11/70. Need to do both of these eventually.
