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
the screen.

We wrote the code out first, obviously.

It was a proof-of-concept experiment in a boring Computer Science A-level
lesson[1]. I'd argued it was possible. Someone else argued it wasn't. FIGHT!

[1] Other experiments included:

a) Can we fill an Acorn A4000's hard drive without the data being findable?
[Yes]
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
plant) [No]
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?
[Three]

As you can see, Printer Switchbox Coding was somewhat unusually high-brow for
us.
