I'm trying to envision the act... Did you wire in each eight-bit word
manually and then use the switch to transmit it, only to disconnect and
rewire for the next byte? That's incredibly stupid and tedious and now I
want to try it. :)
I had something which read one bit at a time from part of the parallel port
("ready" or something, IIRC), and then just flicked the switch from one
channel to the other to send 1s and 0s - timing was crucial. A sufficient
number of bits became words which were stored in memory as code, then
executed. I can't remember exactly what it did, but it made colours appear on
We wrote the code out first, obviously.
It was a proof-of-concept experiment in a boring Computer Science A-level
lesson. I'd argued it was possible. Someone else argued it wasn't. FIGHT!
 Other experiments included:
a) Can we fill an Acorn A4000's hard drive without the data being findable?
b) i) Is it possible to make a "real life" version of the Micro Machines NES
game using index cards as track and 555 timer ICs as cars? [Yes]
ii) Can said game be played without the teacher noticing? [Yes]
c) Will the teacher notice if we use the science technician's barcode gun to
barcode everything in the room (including individual leaves on an spider
d) Can we use the laser printer to print on paper towels? [No]
e) Will we get more marks for our database project if we include little men
who dance to "Swamp Thing" as an Easter Egg? [Yes]
f) How many A4000s can we daisy-chain the power on before something goes bang?
As you can see, Printer Switchbox Coding was somewhat unusually high-brow for
