I forgot about HP and HP/UX, which someone else mentioned here. I guess they're still around, seemingly despite their best efforts to drive their company into the ground in a flaming wreck. The only place I ever saw HP/UX was while working at IBM building printer drivers. It was almost as annoying as SCO to work with.
So there we are in 93 or 94, the 386 just taking off, OS/2 and Windows are still pretty much children's toys compared to UNIX and mainframe OSes, the only commercial Intel UNIX is $1200 for the base OS and the fuckers want another $1200 for a C compiler, you can take your chances with a bunch of BSD tapes and I'd just heard about this nifty new Linux thing coming on the scene.
Almost overnight PCs weren't toys anymore and most of the UNIX workstation vendors are going down in flames. In the late '90's I attend a Linux con in Denver. SGI's there, and their marketroid is telling us their company's betting on Windows NT and storage solutions. I didn't have the heart to ask him why I should buy a storage solution from him when I could get one from IBM and know they'd still be there in 5 years. A few months later, SGI declared bankruptcy. Now my phone's more powerful than their old machines.
Of all the old UNIX workstation vendors, I think IBM is the only one left. SGI's still around, of course, they have an office within walking distance of my house. Dunno what they do these days. At least those fuckers who wanted $1200 for a C compiler also went out of business. Damn I hated working with their UNIX. You couldn't wipe your ass without them wanting to charge you for it. That very first slakware distribution that I downloaded onto 26 floppies was better than anything they'd ever done.
