I know that a lot of you dislike "which was first" discussions, but this one has been bothering me for a while so here goes. At VCF 4.0, there was a nice Commodore display with a timeline that had an entry under "1983" stating that the Commodore SX-64 was released as the world's "first color portable computer." If you search the net, you'll find a number of sites that make the same claim, although you'll find just as many sites that say it was first sold in 1984. It is clear that some version of the SX-64 was "announced" as early as January 1983 as either the Executive 64, the SX-100 and later the SX-64. In fact, it seems that more than one such announcement may have occurred during 1983. "Announced," however, does not mean sold. It is also clear that the SX-64 was "introduced" in January 1984 at the Winter Consumer Electronics Show in Las Vegas. There were a number of articles documenting this. One can be read at http://www.devili.iki.fi/Computers/Commodore/articles/T he_Winter_CES_1984/. This article seems to suggest that the SX-64 had been announced under various names during 1983, but perhaps never sold. As it turns out, the 1983 vs. 1984 date makes a difference. On November 22, 1983, TI made a news release announcing the Texas Instruments Portable Professional Computer (TIPPC), which came with a 16 color screen. PC Week ran the story in its November 29, 1983 issue noting that: "The TI Portable Professional Computer weighs in at 32 pounds, shares the IBM's 8088 processor and runs the latest version of MS-DOS (2.1). The basic model, which will sell in 700 retail stores for $2,395, includes 64K of memory, a built-in nine-inch color or monochrome display, and one half-height 5-1/4-inch floppy-disk drive." Recognizing again that "announced" does not mean "sold" I did some research and found an article in the February 7, 1984 issue of PC Magazine stating that the TIPPC had been "on sale since December [1983]." So, which was first, if "first" is defined (as I believe it necessarily must be) as being available for purchase by the general public? Does anyone have any information indicating that the SX-64 was actually sold in 1983? -W
