Actually, I believe the ZX-81 came out in 1981, as shown below. I bought my Timex-Sinclair in late 1982, if I remember correctly. Also, the documentation that was included with the ZX-81 I have has letters from Sinclair Research dated March 10, 1982, as well as a review of the ZX-81 in Englad dated August 1981. Two interesting things about this: 1) the ZX-81 I have was originally delivered in kit form and still has the assembly diagrams and such; 2) The magazine review, taken from "Personal Computer World" and re-published in "Creative Computing", November 1981, states that at the time, the ZX-81 was available in England but not yet in the U.S. Jeff jeffh(a)eleventh.com -- --------------------------------------------------------------------- Sent from an Amiga 3000..the computer for the creative mind! --------------------------------------------------------------------- Collector of classic home computers: Amiga 1000, Atari 800, 800XL, Mega-ST/2 and XE System, Commodore C-128D, Plus/4 and VIC-20, IBM 5155, Kaypro 2X, Osbourne Executive Radofin Aquarius, Sinclair ZX-81, TI-99/4A, Timex-Sinclair 1000, TRS-80 Color Computer-3 and Model 4, plus Atari Superpong and 2600VCS game consoles.
