If it had become available I'd have taken the 360/50 at UMR or either of
the 43xx machines. I owned a 4381 for a time. At a friend's site in
O'Fallon we brought up a 4341 on VM/SP5 for him to test peripherals.
The deep freeze machines were excellent with the 4361 being at the top
of the heap. All had comm controllers for console and 3 extra
terminals, and the 4361 had a storage director. Only needed to add a
3375 plus some sort of channel attached tape to be running a big PC.
He serviced the IBM check sorters, one of two who did at the time.

But how can anyone home and feed a 370/168?
168? No WAY! Massive weight, water cooling and massive power
consumption. But, a friend of mine had a 370/145 in a bedroom of his
house. We were trying to power it up with the standard
motor/generator set. but, to reduce the parts they had to stock, I
suspect IBM used a one size fits all scheme. The motor was a 20 HP
monster, but the 145 CPU only used about 1600 W DC. Vast overkill,
and the reactive power that motor drew exceeded anything we could
supply. We did get it to spin, but had to have a guy hold the handle
on the breaker!
