The places I worked with IBM hardware was true blue.

Yeah, minicomputers were basically indistinguishable from from mainframes at the end user level. While minicomputers could replace mainframes, there wasn't a lot of incentive to do so. The end users really didn't see a difference, as they had terminals on their desk in either case. All that really happened was that you probably had to buy new applications and convert all your data for a new platform. Minicomputers sold because they let smaller units control their own information. DEC called the PDP/VAX 11/780 a "minicomputer" because a lot of companies would let regional office buy "minicomputers" without corporate approval. No definition I know for "minicomputer" describes a 780, though. I still remember editing card images on a departmental PDP-11/70 running v6 to submit to the computer center 370 running MVS. Seen in that light, desktop computers are the next logical step in pushing computing from a data center out to the user. The first sales I know of were to small companies that couldn't afford the $50K-$100K for a low-end mini, but didn't have any problem dropping $10K on a high-end micro (those were typically S/100 MP/M boxes with somewhwere between 256K and 1024K). Client-server is the result of making it convenient to share data after PC's got both cheap and useful enough to put on people's desk (and we'll ignore the role of big blue having a PC legitimizing them in the eyes of corporate IT managers). > > The original comment was about standardization and the PC market. > > Most of the people playing with PC hardware I knew in the early days > > had done the migration.

TRS-80 model 1s, for instance. Those S/100 system, only running CP/M and less memory were more popular - so much so that you could get a couple of different flavors of CP/M for the TRS-80. There were even C compilers and stripped down emacs commercialy available for CP/M. OS/9 was the best of breed, though. It was *almost* Unix. Same set of file operators, tree-structured directories, good things like that. It ran multi-user quite nicely on a 2MHz 6809 with 64K of ram. Radio Shack sold a version for their Color Computer, and you could actually hang a terminal off the serial port and log in remotely. > > > Which reminds me... has anyone seen the new Intel > > vision of what a > > > consumer PC is going to be?

Well, they may well be right about not needing any more devices, but I don't think USB is going to cut it for speed on disks.
