Cool!
I remember those from the time I was studying. We had 2 of those in one of
our classrooms. AFAIK we got them from some company to play with them, a bit
difficult if you ask me, as there was no controller. So we eventually ended up
to canibalize them for usable electronic parts for whatever project was going on.
I always liked the glass front to slide up and down :)
If I ever can put my hands on one of those myself, then I most likely will convert
it into a small bar like this guy did with a VAX 780 cabinet.

Basically, the big blue box is an IBM 3803 Tape Control Unit - the brain
that connects 3420 Tape Units (one of three is pictured) to an S/370 thru
a Bus & Tag channel. The 3803 and two of the 3420s are from 1972, and the
third 3420 may be from 1980. The 3803 apparently works - it was in service
quite recently - but all three of the 3420s have problems. Luckily, I
obtained a full set of MLMs (service binders) for the units, plus some Bus
& Tag cables.
Note the 3803 has a full control panel. It better, as it has more
electronics in it than most minis of the era.
