== 1-bit, Z80 and ULA == %%toc @@VIGNETTE_WRAP@@1bit.png@@Sinclair spectrum@@musiques_1bit.en@@ This kind of music, which is very recognisable, originates from the beginning of computers, but also on Sinclair Spectrum ZX 48 which pushed the original limits. Instead of being generated by a dedicated chip, the music is created by the fast speed interaction between the CPU (Zilog Z80 for the ZX 48) and the speaker (beeper). But instead of being a simple beep, the high frequency duty can create more richer sounds, and several voices (up to 16).
