Is anyone > on this list familiar with Bell Labs management thoughts > on selling IBM on LSX rather than "dos"? 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. 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.) Doug
