I remember circa 1977 CMU had a PDP-11 compiler for '68 with an extensive
runtime component.
I presume the sources are lost.
Peter Hibbard was the guy responsible if I recall.
Yes, Peter was the author, and he also sponsored a corresponding ALGOL68 subset. My
“history of Algol” web site has information here:
https://www.softwarepreservation.org/projects/ALGOL/algol68impl/#ALGOL_68S
In particular, there is a snapshot with binaries and some assembler files here:

and a later rewrite by C. H. Lindsey in the Amsterdam Compiler Kit here:

See my web site cited above for additional information, papers, and documentation.
