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: https://www.tuhs.org/Archive/Applications/Algol_68/ <https://www.tuhs.org/Archive/Applications/Algol_68/> and a later rewrite by C. H. Lindsey in the Amsterdam Compiler Kit here: https://github.com/davidgiven/ack/tree/default/lang/a68s https://www.clerew.man.ac.uk/#ALGOL%2068 See my web site cited above for additional information, papers, and documentation.
