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
Development container
./work.sh
