I worked on a port of the UCSD p-machine to System/370 (a 4341) in the early 1980s at U. Oregon as an undergraduate taking an OS design course, but the project was abandoned by the department - getting the development environment and terminal interaction modules to function was deemed too hard. The prototype code could execute applications compiled on other p-machines, and had a fairly complete disk I/O package that allowed batch execution to work. The "too hard" decision was taken when we looked at how intermingled the whole development environment was with the various compilers and utilities -- if you didn't have a character addressable terminal, a lot of things really didn't work all that well. Still, it was cool to be able to use the CS department LSI11s and my trusty Apple II to produce code that ran on the big machine. What about things like RSCS v1? I think it could run on bare metal in its early days (morphed later into becoming GCS-dependent in RSCS v2). > I forgot to mention OC/EC (OS/ES), the Soviet era fork of OS/360 that also > borrowed from later IBM operating system releases but that evolved in its > own localized way. At least one machine running this at the Russian climate modeling agency still exists. I believe it is scheduled to be shut down for the last time sometime later this summer once they complete getting the last historical data off it. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
