This massively understates what you could do with the basic 1-bit arrangement. People managed to get music playing during gameplay (I think Manic Miner was first) and even managed to play music with two channels and percussion (Robin of the Wood IIRC).

> and even managed to play music with two channels and percussion (Robin of the Wood IIRC) You think two channels is the limit? Have you heard title music from Chronos? Full multi-channel polyphony, without relying on sound co-processor. I'm not sure where to find the game itself these days, but I found the music itself here [0] on position 31.

Depending on your country you might be able to buy a ZX spectrum for a reasonable price. Their through-hole circuit boards are very repairable and there's a some videos on YouTube explaining how to properly troubleshoot them. I've personally had a lot of fun repairing one I bought on catawiki.

I understand there is an common fault where something, perhaps a capacitor, has failed over the years and if you plug it in something major gets fried.

If you do get one, investigate that before attempting to power it up.

The Retro Games TheSpectrum is not a bad starting point [1], it's very close to the original and you can use HDMI video output and USB power. [1] https://retrogames.biz/products/thespectrum/

It's a Spectrum-like keyboard on an emulator running on a Raspberry Pi like CPU. Nothing like the original imo.

I wrote a few games on the Spectrum and as with most of its hardware limitations we managed to squeeze quite a lot out of it.

My memory is very hazy, it was well over 40 years ago, but I think keeping the timing under control was was one a big hurdle. Because it was single threaded and there was effectively only one interrupt, screen refresh/flyback, so you had to intersperse the music code into the main code and juggle it to even out the note timing.

I remember one game I wrote for the 16K Spectrum, and thanks to an incredibly clever & musical friend we got something like 30 seconds of a tune that had a passable resemblance to Bach's Toccata in about 20 -30 bytes of code.[1]. Every last byte mattered on that machine.

[1] Not 100% on the details but it was about that. We used a combination of base notes and mathematical progression rather than just playing a score as we could get that smaller. I think I've a dot-matrix printout of the games source code somewhere, assuming the ink hasn't faded.

You will find the 10-line Basic Programming Competition quite useful in your endeavours, I'd wager:

https://gkanold.wixsite.com/homeputerium/rules-2026

Some seriously great stuff in there - take the time to go through the archives, set up emulators for the winning systems, and study the results. Its one great resource for the budding 8-bit coder ..

And if you're looking for modern hardware that will get you into the scene, the ZX Spectrum Next is pretty badass - has many cores for other systems available as well, so you're not just limited to Spectrum things ..

For sure, nothing like the original, but it's a cheap, quick way to get you started.

Why not just load an emulator then?

TheSpectrum is great at capturing the original look&feel. The keyboard feels identical to the original. An emulator captures the software aspect well, but that's not all the speccy was.
