This is my point.  Pat doesn't think an IBM 360 would sell for, say, as
much as $50K.  I agree with him that it may not attract the same sort of
frenzy that a PDP-1 would (it's a different dynamic with IBM old iron
collectors) but considering that they are probably more rare than PDP-1's
(which is ironic considering the IBM 360 sold in the thousands(?) and the
PDP-1 had a run of 50) if one did show up, and it was as complete the
recent PDP-8 sale, then there would be a bidding frenzy like you wouldn't

I suspected the PDP-8 could fetch as high as $25K, and I still think this
is a valid number.  Bill Maddox actually got one hell of a deal.  A PDP-1
equipped in an equivalent manner would surely fetch at least $25K, and so
would the equivalent IBM 360 system (maybe a decked out 360/20).

I'd be interested in knowing of any complete IBM 360's out in the wild
(i.e. not already in museums).  From what I know, there aren't many, if
any (at least as yet undiscovered) so I'd like to be corrected if I'm
