Seems unlikely to me, and a lot of energy to get the 3725 to my space.

Not a chance. Don't have the space, power, time, etc.

Definitely. Maybe IBM would donate the license to our museum. ;)

Actually, no. I assume that it is from the main IT group. They have
occasionally sent small things my way. They know that I do not really have
the room to take this.

Thanks for the ideas. I will ask where that came from. At least I could ask
them for first refusal on their disposals. I did rescue a 3275 a few weeks
back. It is considerably smaller - only about the size of a couple of
suitcases. Plus I have some terminals and emulation cards I could hook to
that just to show a typical configuration.
