Nah. It was a totally different world. These companies were competing around proprietary advantages at the OS or hardware level that became less and less relevant over time. HP self-immolated itself and you were left with IBM and Sun.

Only IBM survived, and that’s because it won key contracts in the 60s and 70s to run verticals and business systems, and essentially leveraged mainframe financing and legacy contracts to cross-sell everything. On the tech side, they parlayed that into a sustainable business by virtualizing everything and sharing the Power platform. They get some new business for AIX, but it’s mostly that legacy business.

A good chunk of DEC’s and Compaq’s Business was running terminal (as in tty) operations for mainframes. That went endangered with NT 3.5 and extinct with NT 4. As Linux improved, Intel was good enough. ARM is doing to Intel what Intel did to everyone.
