IBM famously failed to buy the well-established CP/M in
1980. (CP/M had been introduced in 1974, before the
advent of the LSI-11 on which LSX ran.) By then IBM had
settled on Basic and Intel.=C2=A0 I do not believe they ever
considered Unix and DEC, nor that AT&T considered
selling to IBM. (AT&T had--fortunately--long since been
rebuffed in an attempt to sell to DEC.)
