It was a telly, it was flying back - thanks to, imagine it, a flyback transformer. http://en.wikipedia.org/wiki/Flyback_transformer Phil -- "Home taping is killing big business profits.

I said it is more likely he has no education. (Unless you have a low opinion of Cambridge :-))

I can see you now. The kind of manager who delights in belittling ppl. You have all the hallmarks. A total disaster for any company employing you. Graham

I doubt BAH's >stove has a >keyboard input and a display or printer connection.. Actually, it may not have any ports. The PDP-8 didn't even really have an I/O instruction. One of the 8 codes was a NOP as far as the CPU was concerned. You would decode this externally and do the I/O operation with external hardware. Most PDP-8s had a current loop interface built onto them for the paper tape reader. > >Graham > -- -- kensmith(a)rahul.net forging knowledge |
