circuit logic, where all connections have to complete their loops, is profoundly thrilling. Peter Samson, who early on appreciated the mathematical simplicity of these things, could recall seeing a television show on Boston's public TV channel, WGBH, which gave a rudimentary introduction to programming a computer in its own language. It fired his imagination: to Peter Samson, a computer was surely like Aladdin's lamp--rub it, and it would do your bidding. So he tried to learn more about the field, built machines of his own, entered science project competitions and contests, and went to the place that people of his ilk aspired to: MIT. The repository of the very brightest of those weird high school kids with owl-like glasses and underdeveloped pectorals who dazzled math teachers and flunked PE, who dreamed not of scoring on prom night, but of getting to the finals of the General Electric Science Fair competition. MIT, where he would wander the hallways at two o'clock in the morning, looking for something interesting, and where he would indeed discover something that would help draw him deeply into a new form of creative process, and a new life-style, and would put him into the forefront of a society envisioned only by a few science-fiction writers of mild disrepute. He would discover a computer that he could play with.
The EAM room which Samson had chanced on was loaded with large keypunch machines the size of squat file cabinets. No one was protecting them: the room was staffed only by day, when a select group who had attained official clearance were privileged enough to submit long manila cards to operators who would then use these machines to punch holes in them according to what data the privileged ones wanted entered on the cards. A hole in the card would represent some instruction to the computer, telling it to put a piece of data somewhere, or perform a function on a piece of data, or move a piece of data from one place to another. An entire stack of these cards made one computer program, a program being a series of instructions which yield some expected result, just as the instructions in a recipe, when precisely followed, lead to a cake. Those cards would be taken to yet another operator upstairs who would feed the cards into a "reader" that would note where the holes were and dispatch this information to the IBM 704 computer on the first floor of Building 26. The Hulking Giant.
The IBM 704 cost several million dollars, took up an entire room, needed constant attention from a cadre of professional machine operators, and required special air-conditioning so that the glowing vacuum tubes inside it would not heat up to data-destroying temperatures. When the air-conditioning broke down--a fairly common occurrences--a loud gong would sound, and three engineers would spring from a nearby office to frantically take covers off the machine so its innards wouldn't melt. All these people in charge of punching cards, feeding them into readers, and pressing buttons and switches on the machine were what was commonly called a Priesthood, and those privileged enough to submit data to those most holy priests were the official acolytes. It was an almost ritualistic exchange. ACOLYTE: Oh machine, would you accept my offer of information so you may run my program and perhaps give me a computation?
PRIEST (on behalf of the machine): We will try. We promise nothing.
As a general rule, even these most privileged of acolytes were not allowed direct access to the machine itself, and they would not be able to see for hours, sometimes for days, the results of the machine's ingestion of their "batch" of cards.
This was something Samson knew, and of course it frustrated the hell out of Samson, who wanted to get at the damn machine. For this was what life was all about.
What Samson did not know, and was delighted to discover, was that the EAM room also had a particular keypunch machine called the 407. Not only could it punch cards, but it could also read cards, sort them, and print them on listings. No one seemed to be guarding these machines, which were computers, sort of. Of course, using them would be no picnic: one needed to actually wire up what was called a plug board, a two-inch-by-two-inch plastic square with a mass of holes in it. If you put hundreds of wires through the holes in a certain order, you would get something that looked like a rat's nest but would fit into this electromechanical machine and alter its personality. It could do what you wanted it to do.
So, without any authorization whatsoever, that is what Peter Samson set out to do, along with a few friends of his from an MIT organization with a special interest in
