I am a volunteer and on the board of directors for the Rhode Island Computer Museum. I maintain the Teletypes, a PDP-8/I, a PDP-9, a PDP-12, two Altairs, an IMSAI, a 1965 vintage Wang calculator, and many other vintage computers at the museum. I have many 1980s and 1990s vintage Sun Microsystems and SGI servers and workstations, 4x DEC PDP-8, several PDP-11, and a PDP-10 in my home collection.
