Ooh, thanks for that; I have long been intrigued by Burroughs ... they
always tried rather unusual approaches ... seeing if I can get MCP fired up
sounds like a fun weekend project.

As I recall, the I/O in the Algol-60 report was not particularly

I probably started it; I just mentioned the PDP-11 one because a lot of
people already have either 11's, or an emulator up and running.

Why all this DEC stuff about Algol? Go to the so

It was a cross compiler. The compiler ran on TOP-10

Both of those requirements are already done:
