The original Tandem OS (called Guardian at the time) was written in Tandem's TAL
(Transaction Application Language, amongst other productions), a vague evolution of
HP's SPL that looked more like Algol, starting in about 1974. That is also the
earliest I know of an operating system being implemented entirely in a high level
language.
Most likely the earliest operating system written in a high-level language was the one for
the Burroughs B5000 (early 1960s), written in a dialect of Algol 60. Others: Multics,
written in PL/1 (starting in mid 1960s), the operating system for the Berkeley Computer
Corporation’s BCC-500, written in BCC SPL (system programming language) (late 1960s), OS6
by Stoy and Strachey, written in BCPL (early 1970s), Xerox Alto OS, written in BCPL (about
1974).

About 1972 the Department of Computer Science at Strathclyde University in Scotland had an
operating system implemented on a front-end-processor (Icant remember the make) that
allowed the submission and control of jobs to a “mainframe” - an ICL 1904s.
The operating system was written in STAB - a language initially designed and developed by
Professor Andrew Colin - and loosely modelled on BCPL.
My memory is that the FEP was about 12 19” racks, it supported about 15-20 users and did
not lose your files terribly often ;-)

Paul beat me to it.. HP's SPL and Tandem's TAL were old news by then ...
In fact the HP's 3000's and HP 9000's stack architecture was model from
the
B5000, see below...
