Hi Folks, I have an original IBM model B computer controlled typewriter witha lot of spares and maintenance manuals available for sale ortrade. This stuff is impossible to find. As used on the IBM 1620,DEC PDP-1 and many other computers of the era. Useful if you'remaintaining one of those or want to build a replica/simulator. Respond to me directly as I'm not a member of this list. Thanks, Erik
