I came across this article earlier, and it seems that I have four of these computers already, and gave a fifth one away a year or two ago. I've got a 3COM Audrey, an Atari Portfolio (currently loaned out), a Commodore Plus/4, and a TI CC-40. I had a boxed and well worn Timex Sinclair 1500, but gave it to a friend on another forum some time back.
Anyone have any of these, or do you have computers that you think should be listed in that article? I've got a Tandy/Radio Shack Videotex computer, which was the precursor to the Color Computer line, and was built for online access for farmers in 1979-1980. I've also bought and given away a Commodore Colt and a Radio Shack PC-2 handheld. I even have an Apple eMate 300, the ruggedized laptop version of the Newton PDA that was made for the educational market.
