Small ICs then. Oh well. I don't even know if it was air or water
cooled. What would you estimate for bits/chip?

When they broke up the /195, I had a chance to get a memory board
as a souvenir, but I was sick of it by then. Should have got one!
There were /lots/ of them. The thing filled a very large computer
installation. (disk farm, rows of tape drives, line printers,
(I think they even had a page printer of some kind on it), terminal
equipment, card readers/punches).

Oh, more than that I think. It was definitely faster than a VAX
11/780. It may have gone through CPU upgrades while at NSA, too.
(I didn't meet it until around 1980, when it had gone to the Navy.)
It's also possible that the original specs were deliberately
understated, too.
