I probably missed some things too. Especially kits, foreign systems, and foreign kit systems. I identified some themes, already implied by Evans' and others' choices. Mabye they'd make OK info card headings. Word processor unit removed, as addressing that market should reflect some diversity of the systems (Wang, Vydec, Sony etc). Also needs more space. Have to trim anything that was merely sentimental, popular, or cool, or just available in collection for: Technical Innovation, Market Significance, and Historical Narrative. For instance the Franklin has to go in-- it made ROM copyrightable, if not on purpose. Compaq's 386, beating IBM to the punch, signified more than any other system that the Clones had bested IBM, and would come to dominate. I think the PCjr line can go, but I wanted to make another silly sequel reference. I believe first Fujitsu then the PC-88 were the real dominant market players in Japan; BBC Master was the Apple II of England (fondly remembered school computer), ZX and MSX the real international players, France's never went EU wide. That's five international picks of what I feel should be six or eight. Six would add up to 40 systems total picked above, which it seems is the 20-rack goal, including both shelf levels. This eludes the history of the midrange/workstation, which gets micro-ed on the inside and out beginning around 1981. I left two gaps, in as much as I used the Apple II twice and used one Atari only. Systems separated by slashes meant to indicate either/or, as space dictates. I tried to be as ruthless as possible-- I think no platform got more than 2 machines. Despite my predilection for macs, I think you can tell the story with just one (and the LISA) and not even a significant one (the 128k). The early interface is too alike the LISA's to demonstrate/differentiate well to the layman. I confess a soft spot for the Archimedes as we're all running way more ARMs than any other processor these days. Kudos to anyone who appreciates my stupid Movie/Car refs/Old-Fashioned Hyphen-ization. I hope I didn't do anything improper with the line breaks. --
