Burroughs ESPOL has been dead since the early 1980s. The B6700/B7700 MCP (OS) was
completely rewritten at that time in a new language, NEWP, which is somewhat MODULA-like.
It is still in use for the Unisys ClearPath MCP systems that have evolved from the
B6x00/B7x00 systems.
I remember looking at various ALGOL dialects on the B6700 system back in 1975, when I was
trying to read DEC format tapes on the TUE Burroughs system. MCP doesn't make that
easy. I looked at DCALGOL, which didn't quite do the job. I see from the Unisys
ClearPath webpage that was mentioned that DCALGOL is still around. I don't think
ESPOL was suitable either, but that was mostly because it wasn't available in any way
shape or form for ordinary users.
I ended up using an OS/360 system instead, with EXCP mode I/O. Fun.
