Check _www.vintage-computer.com_ (http://www.vintage-computer.com) and do a post. Also check their links, especially I think it is _www.bitsavers.org_ (http://www.bitsavers.org) [com?] in Britain. They have free downloadable manuals for some Kaypros and other computers, which should give you the specs. "Sharkonwheels" posts on this site and he is big into a lot of Kaypros, but not the 2000 I think. You can also check my website for other contacts - _www.kayprosts.org_ (http://www.kayprosts.org) . But I am more into the first Kaypros before 1984. Kaypro 2000 certainly was something for its time! Good luck! Frank In a message dated 8/29/2008 12:45:34 P.M.

I got my hands on one and while it's nice and heavy I would like to turn it on.. **************It's only a deal if it's where you want to go. Find your travel deal here.
