True, but back in those days, that wasn't a fatal limitation. Besides,
the 8-bitters didn't really have a OS, more of a structured program

In retospect I would say people expected BASIC to run rom. I/O
was a feature only used to save your programs, maybe even data.
The Apple,TRS-80?,Pets,C64's,Coco's,IBM-PC all come to mind.
CP/M was the most common real OS, but lets not forget about
6800/6809 machines running FLEX or OS/9.
