While there certainly are RSX-11 and TSX-PLUS machines on the Internet via full-blown TCP/IP implementations, you're right, maybe they were always cute host names.

True, and many places have a specific policy of providing empty or false HINFO fields as an attempt at "security through obscurity".

TSX-11 was a timesharing version of RT-11 which ran on top of RT-11, which I used while I was in high school, so I named my workstation after it in homage to that quaint old system. When I put the Linux FTP site on my workstation, and later moved it off onto its own dedicated machine, the name tsx-11 followed it. (I name all of my machines after Dec OS's and programs. For example, I'm currently typing this message on DCL, my Sparcstation 5. And my Laptop running Linux is RSTS-11. And my NT workstation machine, which I have to use for work?

TSX-11 was the name of an operating system, the Time Shared Executive for the PDP-11. I was never impressed by the design of TSX, but it did work, and there were folks who liked it.

You'll get no argument from me about the quality of IAS. It's my favorite (and perhaps least well known) member of the RSX family. It had a lot of features that later appeared in VMS (timesharing and real time scheduling, DCL, a wide selection of privileges). It also had "handlers" instead of "drivers" - the difference being a handler was a full sized task, instead of a skimpy set of APRs and an interrupt routine, like on the other RSX family products. It also had the best RMD available - it allowed you to zoom in and out of a partiton display, to get a detailed look at what was in memory. Lee K.

So if you SET CPU NOFPP then you definitely won't hit it. And this only matters under VirtualPC, it works fine on a real math coprocessor, even one with the old Pentium FDIV bug.

Also I don't believe the copy I tried out was your latest. I was mainly interested in seeing if it would let me boot a OS and do a couple basic things.

Now I wish I >hadn't thrown out my old RSX-11M distribution tapes ten years ago! M-PLUS had I/D space as well as Supervisor mode on the processors with Supervisor mode. Allowed for much bigger non-overlaid tasks with code separated into intructions and data and supervisor mode libraries. M-PLUS wasn't halfway to IAS but an entirely different animal entirely. It would even support 4 CPUs. It was developed on CASTOR the (in)famous PDP-11/74 a 4 processor 11/70. IAS was the timesharing system based on RSX11D. All the later flavours of RSX, 11S, 11M, 11M-PLUS were all decendants of 11D. Even VMS traces its roots to 11D. This is very evident in some of the system APIs.
