Well, I have a bit of a dilemma and I am seeking advice. (No flames,
please.) As so many on this list I abhor seeing things scraped if they are
useful. As with much of the older mainframe stuff, however, it is very big,
and an isolated unit is not generally useful by itself. So here is my
problem. Our museum is a part of a big state university. I go by the surplus
department once in a while and see some interesting stuff that I take back
to our space and add to our inventory. If it has a residual value on the
books then it is transferred to our department. If it is not on the books
then I just take it and there is no record of it. In the latter cases I have
been known to swap newer stuff for other older stuff we are interested in.
Yesterday I went by and there was a nice IBM 3725 front end processor. It is
not anything attractive for a museum visitor to look at. It takes up a lot
of valuable display space (roughly 2 racks & about 5' tall) for something
kind of obscure (for most people) and not at all visually interesting.
Now I have no idea what our surplus department generally does with such
things. Assuming that there is no actual market for it, I could probably go
over there and get it for our museum. Right now I could probably even store
it, at least until something more attractive came along. On the other hand,
when we get to the point that we are a bona-fide museum, with lots of
visitors, I can see raising some much needed cash by parting this thing out.
I am sure there are lots of boards and control panels that could be sold
individually. I would envision tagging these parts as being a souvenir of
the museum, much as I will with punched cards, 8" floppy disks, 5-1/4"
disks, etc.
I guess a third alternative would be to sell or trade it to somebody on the
list for something that is more visually interesting and perhaps smaller.

Gil,
If you are in the enviable position of being able to acquire and store this at
all, you never know what you will run across in the future. You might be albe
to trade it to someone with channel attached systems who could use it, or
you might acquire a collection or processor which would run it.
If I'm not mistaken the 9121 on Ebay right now would run it, at least if
the 9191 will do 370 mode. I believe that it has XA mode and probably
ESA mode capability and the 3725 might not be operable on it, since you
probably would not have access to an OS due to license costs, on anything
but the 370 arch.
Also, this makes one ask oneself, what hole did this crawl out of, and is
there more? Have you asked that? Maybe there will be more to follow
that would go with this, and you could head off any further shipments by
that department to the scrap heap.

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. ;)
Also, this makes one ask oneself, what hole did this crawl

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.
Maybe there
will be more to follow that would go with this, and you could

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.

At least the 9121 guy has some new pictures. Same price, however.
Anyway, not all 3725s are channel attached. Some were made for remote
sites and talk to the mainframe over leased modem lines (probably should
be called "far end processor").
