Pi’s have a knack for reinvigorating retro tech. Enjoyable one from keyvin on GitHub:
I’ve created a video interface for the z80 with a raspberry pi pico. Tackle choice is achieved by way of a 74HCT154 and 74HCT32. Z80 Wait states are triggered when the Pico’s deal with is decoded by way of the 74hct32. At the moment the Pico implements 4 IO ports – knowledge register (00), x register (01), y register (02), and xy-width register(02). RGB ranges come from the opposite PIO by way of a resistor DAC. The scanvideo library in pico-extras says it now not helps 8bpp, so I wrote my very own quite simple 640×480 video mode fed by way of DMA. The Pico implements a 160×120 8 bit shade output for the z80.
