Here are some links to other sites featuring television equipment that I enjoy.

Tim Stoffel's Quadruplex Park - This site includes a history of VTR's, a discussion on how videotape recorders work, detailed information on common and rare VTR formats, Ampex and RCA equipment catalogs, pictures of various VTR's and equipment and more links to other sites. Site also includes some digital equipment such as an ACR-225. See how 45,000 pounds of equipment was moved from Rochester, NY to Reno, NV on a shoestring budget. Be sure to take the recently updated Quadruplex Park tour.

Ed Cushman's link isn't working right now. Ed Cushman - Yet another collector. Here you can find a brief history of the quad machine and photos of his two VTR's.

Museum of Early Video Editing Equipment and Techniques - This site contains information on early videotape editing equipment and the techniques that were used to splice videotape (yes, I said splice). Detailed information on early electronic editors can also be found on this site.
