I did not get that far into it - I built it on an -8/m at Ohio State (they used to have a pair of /ms to collect and analyze data from a mass spectrometer for the purpose of looking for performance enhancing drugs in horse urine for the state racing commission), and on my own -8/a w/KT8A and 128kW of MOS mem. Mostly, I have built RTS-8 per the instructions, including an example program or two, and did get the OS/8 task working on it with little effort. I never attempted to do any "real" work or development on it, since, at the time, it was to me a curiosity, and didn't give me anything I couldn't already get from an ordinary OS/8 system. If I could have run two or more OS/8 tasks (which I do not think is possible by default), that would have made it more interesting to me. If you have all the sources and the contemporary docs, my recollection is that everything builds and runs as documented. I do not remember any 'gotchas' or any undocumented tricks. ISTR that it was mostly useful as a starting point for your own development. There were a few sample programs in the docs to demonstrate how to work with co-routines and how to pass messages between tasks, but essentially no ready-to-roll-out applications for it. I also have a memory that by the time v3 came out, the expected platform was an -8/a w/more than 32kW, but that was mostly so you could run an OS/8 task with the full 32kW for it and still have some core left over for RTS-8 itself. If you can get away with 16kW or 24kW for OS/8 (no ADVENT for you!), then it should run fine on a maxxed-out -8/e. If you don't care about running an OS/8 task while your code is frobbing your I/O cards, then memory is less of an issue. I believe that is the case, but until this year, I hadn't ever run across more then mere mention of DECnet-8. Only recently, I have at least found (on bitsavers or one of the other major repositories) some docs on it. I looked for it 22 years ago, but was unable to trace it down then. I don't believe it does much more than simple message and file passing, and I don't think it's compatible with DECnet on any other platform, but it _is_ vendor-supplied basic networking for an otherwise ignored architecture. -ethan -- Ethan Dicks, A-333-S Current South Pole Weather at 21-Oct-2008 at 22:30 Z South Pole Station PSC 468 Box 400 Temp -45.6 F (-43.1 C) Windchill -70.2 F (-56.8 C) APO AP 96598 Wind 7.3 kts Grid 342 Barometer 679.5 mb (10647 ft) Ethan.Dicks at usap.gov http://penguincentral.com/penguincentral.html
