The Computer History Museum has a PDP-1.  It has been
underdoing restoration, and I saw the CPU running
diagnostics at an event there last Saturday.  The
museum actually has three PDP-1s, including the
prototype and another that is "on tour".  As far as
I know, these are the only PDP-1s known to exist.
A member of the restoration team said that only
50 were manufactured.
