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).
The Spectrum, along with the C64, NES, SNES, etc is still on my to-do list of catching up with computing/gaming history by devving some games for the platforms that started it all ;")
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.

Bought one at a garage sale for 5 EUR. I'm pretty sure it does not work. Haven't tried it: I still have a good old CRT TV so I could.
But when people talk about coding for these 8-bit machines, they usually mean they'll target an emulator.
