I thought it would be a good idea to create a timeline for the development of the Sinclair ZX81, but unfortunately, my knowledge is not sufficient.
So far I have:
March 1981 - Sinclair Research Limited launch the Sinclair ZX81 with 1K RAM - the first home computer for less than £100 (in fact it only cost £69.99 or £49.99 in kit form)
??? 1981 - 16K RAM pack launched by Sinclair
November 1981 - Sinclair Research Limited launch the ZX Printer - a thermal printer compatible with the ZX81 (although you needed an upgraded power supply) - cost was only £50
??? 1981 3D Monster Maze launched with a Tyrannosaurus Rex which scared a generation of teenagers experiencing their first home computer games.
??? Release of first full-sized keyboard for the ZX81
??? Release of Quicksilva sound interface
??? Release of Quicksilva hi-resolution graphics interface
??? 1982 - First hi-resolution game (Forty Niner) released which produced 256x192 resolution graphics on the ZX81 entirely in software.
1991 - Launch of the World Wide Web
May 2008 - Launch of the English ZX80/ZX81 Forums - http://www.sinclairzxworld.com
January 2011 - Release of Boulder Logic by Bob Smith
2010 - XX new games released for the ZX81
Mar 2011 - Soft Launch of the Sinclair ZXpand interface
May 2011 - Conversion of 'Nanako in Classic Japanese Monster Castle' released by the Mojon Twins
May 2011 - Official Launch of the Sinclair ZXpand Interface to the open market.
There is probably a lot more we should add!

Re: Sinclair ZX81 Timeline
We should probably mention the ZX81 remake of Manic Miner in 1984 !
