Thats nothing: I spent my first two years at University doing Pascal exercises on the Honywell Multics. This used nine bit bytes and a thirty six bit word. Its epoch was 1900 and it counted microseconds into a 72 bit unsigned int (this was in PL/1 which is like C but with more type co-ercion facilities). To fill up a few more lines, let me add that Multics also gave you keyword access to records in files as part of the OS. Pascal gave records in files indexed by integer. The compiler converted the index integer to ascii so record 45 was accessed via key string "45".
