From the project
VideoULA replacement for BBC Micro - 44 pin XC9572XL version
This repository contains the hardware design and firmware for the VideoULA V01, a drop-in replacement for the VC2069 Video ULA (IC6) in the Acorn BBC Micro Model B.
The original BBC Micro Video ULA (IC6) is a custom ASIC that is no longer manufactured. Failed or missing ULAs result in a non-functional machine. This project provides a modern replacement using a CPLD and a small external SRAM for palette storage.
