In the B5500 emulator repo: https://github.com/pkimpel/retro-b5500/tree/master/source
It is still to be proofed though.

It is suggested in the oral history at UMN.edu that the B5000 was designed as an ALGOL machine and Burroughs had the idea that only compilers would generate machine code, so they made the B5000 compiler friendly, and the system would have an OS to manage resources, so it was designed around drum/disk being an intrinsic part of the system.
