[Milsurplus] RS-6 ID thot

Water cooled computers... now that brings back memories.  About 10 - 11
years ago we received a "good news / bad news" letter from IBM.  Good was
that after about a year or more of selection process, our company was
selected as the successful bidder for flowmeters to monitor the cooling
water flow.  Bad was that they had decided to cancel the product our meter
was going to be used on.  At the time our V.P. of Operations framed the
letter and put it up on his office wall.

If anyone wants some old mainframe and system software documentation,
there are several bookcases full in the basement beneath me that my
employer will be discarding soon. Bring a pickup truck. If you hurry,
you can get the last dual 3490 tape unit and some controllers we're
removing from the Operations center, too. Unfortunately the 3420 round
drives (like the ones you always see spinning in movies when they show a
big mainframe system) were sent to their doom last year. They sure were
fun to watch - complete with the automatic door.

I helped disassemble an old system with an outboard chiller when I first
got here in '96, IBM 3090. It was set up so that the water ran through
its own cooling circuit but could be switched to the public water supply
in the event of a breakdown. This had to be done swiftly to prevent
processor meltdown. I have some of the big gray cables from the beast at
home in my garage that I saved for some unknown reason. There's a power
supply for a 3480 sitting here in my office, too. Must be the rows of
fuse holders that attracted me.
