I have a Sperry Univac XT out in storage, just a simple PC with basic 16-bit ISA bus, 360K and 10 meg HD.
The best thing about it is the Sperry Univac Name tag.
We had some Sperry pcs at work too. There's a rocker switch on the front for the power. I think they had DOS 3.3. Nothing special about them.
I remember someone typed in format c: and it said press any key to begin format. They didn't know how to get out of it so they called me over, and I used that rocker switch to turn it off. Ctrl+C might have worked, but nobody wanted to take that chance.
Many, many years ago our New York City computer club had a demonstration of voice recognition by an IBM team. Someone at the back of the room stood up and yelled "format C colon"!Reminds me of when i did a Dir of a directory then did del *.* forgetting that i was still in the groups modification document folder and deleted all the records of plant modifications !
Thank god for undelete
