My dad was a computing professional in Scotland in the 1970s. He received a couple of industry trade magazines every week, such as Computer Weekly and Computing. In one of them, I remember there being a cartoon strip called Computability Brown (a pun on Capability Brown, the 18th century landscape architect), but I've had no luck finding references to it.
What I remember:
There was usually a mainframe printer in the background going “dump dump dump”. This might be a hint that the strip was drawn by Dickens, as he was famous for writing indicative words to express emotions rather than drawing expressions.
The time frame would have been likely between 1977 and 1984.
There doesn't seem to be good archives of either of these magazines, so I'm not finding anything to back up my memory.
