On this page I have put together some DIY udgrades for many Atari 680xx computers. The current projects are from the Tavern BBS, but future expansion, I hope, will include material from magazines and other internet sites. If you have details of an upgrade not on this site would you please send it to me, so that I can include it on the page. I have tried to give credit where it is due but if you see one of your projects on this page without any credits tell me and I will recify the situation.

Disclaimer

None of the upgrades on these pages have been tested or written by me, Gareth Morris. I have only converted the text or pictures to a format suitable for HTML. The use of the information is at your discretion and risk. Any damage to person or property caused by the use of these projects is nothing to do with me. You have been warned.
