ceda2vga

A video adapter for Sanco 8000 series computers, to use your handy flat-screen VGA display.

This project is part of a reverse engineering effort of a Sanco 8003 by RetrOfficina GLG Programs. Also see ceda-home.

How it works

A Raspberry Pi Pico syncs with a Sanco-generated frame, captures and stores it; then the frame is sent out as a VGA signal. This project extensively uses pi2040's PIO peripheral and DMA capabilities.

Setup

./setup.sh
