  Algol 60, that is. It was used as the inspiration
by just about
 everything that followed 
 I've just remembered that the Algol (probably Algol-60, but the manual
 doesn't say) interpreter used for the programming languages course at MIT was
 adapted from the Delphi (a homebrew PDP-11 OS used at MIT) version, to a
 version that would run under Unix V6. So it should be runnable under any
 PDP-11 emulator. 
There?s DECUS ALGOL, which is essentially a PDP-11 version of Burroughs Extended Algol.
It generates bytecode which even looks somewhat like B5500 machine code.  I still have a
copy, though I need to do some work to find the correct sources and build procedure for
the runtime support code.
