* Cambridge CAP computer - [http://research.microsoft.com/pubs/72418/cap.pdf source]- All procedures constituting the operating system were written in [[wp:ALGOL 68C|ALGOL 68C]], although a number of other closely associated protected procedures - such as a paginator - are written in [[BCPL]].

Note: The Soviet Era computers Эльбрус-1 (Elbrus-1) and Эльбрус-2 were created using high-level language uЭль-76 (AL-76), rather than the traditional assembly. uЭль-76 resembles Algol-68, The main difference is the dynamic binding types in uЭль-76 supported at the hardware level. uЭль-76 is used for application, job control, system programming[http://www.ixbt.com/cpu/e2k-spec.html].
