ZX Spectrum Music Making

Having spent a fair bit of time over on my other blog looking at ZX Spectrums, I thought it about time I dragged some of that over here and looked at music making 1980s computer style. This shows everything I had back in the day for my ZX Spectrum. The hardware (from left to right): … Continue reading ZX Spectrum Music Making →

AY-3-8912/8910 Hardware Emulation – Part 2

Having explored how an AVR can be used to emulate the AY-3-8912/8910 in AY-3-8912/8910 Hardware Emulation I wanted to have a go at using the very common ATMega328P to do the same. But rather than wire things up on breadboard, I put together a quick PCB to allow me to do some experiments. Spoilers: This … Continue reading AY-3-8912/8910 Hardware Emulation – Part 2 →

AY-3-8912/8910 Hardware Emulation

The 40-pin AY-3-8910 devices I've been playing with are no longer newly available, but they are pretty available if you are happy with a certain questionable quality (more on that here: Arduino and AY-3-8910). But the slightly shorter version (with fewer general purpose I/O pins), the 28 pin AY-3-8912, seems a lot harder to find, … Continue reading AY-3-8912/8910 Hardware Emulation →
