So I'm guessing you also know what at Bistable flip flop is, not to mention a full or half adder.
I only had a passing knowledge of Hollerith cards. When I first started computer studies at school we had to write our code on coding sheets and then type it in on a punch card machine. The cards were sent off to the local University and two weeks later we'd get a print out of the result or, if you were unfortunate, just the word ERROR. About mid-way through the year the school got two Commodore Pets - at the time they seemed incredible.
Any sorry about that - back to the world of Spyders
