OS Software (link)
Ron Crandall found a tape containing some source code listings of the BTI-8000 operating system. Tom Poulter gave permission for him to share them online, so here they are. Unfortunately, they aren't complete and many of the included header files are missing, but it still provides a wealth of information about the OS and how the instruction set was used in real life. The most interesting document has to be the core operating system listing, SYSTEM.LIS. You can also grab a zip file containing all the files.
