GE had a "red light/green light" system. When the main frame was stressed, you got a red light and had to take a break... and those rainfall run off calculations? I did those after converting the software from the Wang mainframe to brand new, top of the line, MS basic on an IBM AT.
Another place I worked was still doing most of their calculations on an IBM Sys36 - we'd telnet in from "dumb terminals" more powerful than the S/36 itself, but the company was too cheap to rewrite the software for the new computers.
No tape drives, though, so far as I know. One of my employers DID invest in a top of the line laser WORM drive (write once, read many) then promptly placed it by the window in their office. By 2:00pm every day, it was so hot from the afternoon sun you couldn't write to it. We'd store everything local, then batch file new completed drawings first thing the next morning.
Technology, right?
