One of the giants of that era, Niklaus Wirth, passed away on New Years
Day, six weeks before his 90th birthday.

He became disillusioned with the directions that Algol 68 was going. He
designed Algol W as a competitor. Algol W became Pascal.

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/
 

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

https://www.clerew.man.ac.uk/#ALGOL%2068

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

I once had DECtapes with the (Bliss) sources of the runtime part, but I lost 
those long ago.  And I never did have the other parts of the compiler.  Yes, 
that would be neat to find.  I believe this compiler was for the CMU home-grown 
PDP-11 OS.
