The BCM hsed to (pre PC) have a Honeywell, SAGE, PDP-1
and numerous
machines of former glory on display. Now they are somewhere parts
unknown or the back room. Next time I'm in town I should stop in and ask
if I can see the real machines.
You won't find any of that stuff since it has all been moved (or is being
moved) to California. The museum has set up a new warehouse in Moffett Field,
on an Air Force base I believe. They intended to make it available to scholars
and other interested people.
When I visited they had just set up shop and the collection was incomplete
(the PDP-1 was there, but it was disassembled to the module level and piled in
a box... I wouldn't relish the job of reassembling it.) By now I'm sure most
of it has been moved out of Boston.
Although the museum has done some pretty boneheaded things in the past, I give
them credit for the move, and I believe they've been much more careful since
then about tending their collection.
