Scary
- not the track, the fact that I have actually owned all of those bits of hardware over time, and recognise the sound of tape loading programs well !!
Ah, the little ZX81 - popularly known as the doorstop at the time because of its shape and that was about all it was good for.

You wouldnt believe how amazing cleverly cheaply that thing was made at the time.. They used the Z-80 processors spare cycle time while executing NOOP instructions to update the video hardware, which is why you get all those funky color bars around the edges while its loading. The 80's version of DMA.
(For those who dont understand the intricacies of microprocessors, thats kind of the electronic equivalent of tying dusting mops to your cats feet so it wipes the floor for you while walking around the house. Processing power was expensive back then !)
The idea of making music with Dot Matrix printers and Drive voice coils has been done too.. (not with funky video like that though)
<creaky voice> I remember a program that played god-save-the-queen on the commodore-64 floppy drive by vibrating the read-write heads at the appropraite frequency - probably not great for the disk alignment, but good for a laugh (I dont think LOL had been invented then). - Seriously

If you like Printer Music, check out this Gem from the 1995 Melbourne Techno/Rave scene.

Ah the sweet sounds of a dot-matrix printer head doing its thing..
OK, I feel like an old-fart now, I'm going to go spindle-fold-and-mutilate some punch cards or something. _________________ Great minds discuss ideas. Average minds discuss events. Small minds discuss people
