Remembering the CDC 6600

Stil coding ...

OH YEAHH !!!

It was a lovely machine to write code for. I used one at the University of London in the later 1960s - I've still got my SCOPE, FTN and Ascent F manuals. Is there anybody else out there who used the SYSTEMC routine ? This was a wickedly useful procedure which allowed a running program to get directly at the OS and do things like over-riding fatal errors, mess around with your job control limits and other naughty things. CDC tucked the documentation for this practically out of sight in an appendix to the SCOPE reference manual. Once again, it was a wonderful machine to work with.
