CTOS! Or BTOS as Burroughs called it. An early microprocessor OS written by Convergent Technologies for business users. Ran in 128K!
It was based on a message-passing system that allowed diskless workstations to connect over HDLC to a server. Zero-administration networking (just run the cable and it came up).
Derived from an Intel message model RMX86(?) it shipped on 1M machines in the 80's

- kaetemi 5y agoI believe there are some images floating around in CD-i homebrew and emulation circles.
- hsnewman 5y agoI used BTOS for about 5 years in the mid 80's. I loved it, we used a 4GL programming language from Progress Software.
- JoeAltmaier 5y agoMy first job out of college was working on BTOS! I worked in the file system, the video driver, the kernel, drivers (keyboard/mouse/card scanner), network, cache and on and on. My favorite job ever!
- EvanAnderson 5y agoI was enthusiastic to post a link to a comment about the ingenious syscall convention in CTOS[0] that exploited x86 segments I learned about a few years ago on HN. I did some searching to dig it up and realized you posted it. >smile< [0] https://news.ycombinator.com/item?id=12290436 https://news.ycombinator.com/item?id=12290436
