Dave Fehr, who passed away in early 2019, and John Kendall, friends and workmates from Wisconsin DOT. Dave did very good work with stained glass, and we have a couple of his pieces.
I have also contributed to, and benefited considerably from the document archive at www.bitsavers.org .
Other collectors and collections:
Paul Pierce’s Museum: Paul has a varied collection, including unit record equipment and mainframes (the best collection of those I am aware of) and minicomputers. Recently Paul has made significant donations from his collection to other museums.
Carl Friend’s Museum: Carl has a very good collection of minicomputers. Also, he has taken the time to provide much more explanation than I have on my pages so far (but maybe my new site will improve things. 😉 )
The UNIX Heritage Society: If you are “into” the origins and history of Unix, this is a “must visit”.
Professor Douglas W. Jones of the University of Iowa has a good bit of information on PDP-8’s and a pointer to the Museum of HP Calculators. The PDP-8 information contains pointers to several good sources of information. The HP pointer was the first I followed to the HP Calculator Museum.
The S100Computers page: John Monohan and crew design some pretty nice boards that can help with managing and maintaining old S100 systems. There is also a pretty good store of documents on the site: follow the links from individual boards listed under “S-100 Boards”.
