Networking giant Novell bought Digital Research
and it's DR-DOS line with a view to using DR's
product line as a lever in their comprehensive
strategy to break the Microsoft monopoly.
The planned DR-DOS 7.0, intended to trump
Microsoft's troubled MS-DOS 6.0, was repeatedly
delayed. When it eventually arrived, renamed
Novell DOS 7, it was a disappointment. It was
larger and introduced many new bugs, and the
main functional addition was Novell's second
attempt at a peer-to-peer networking system,
Novell DOS 7 required several bug-fix releases
and was not completely stable when the next
development occurred. Eventually, Novell sold
the product line off to Caldera Systems in 1996.
