Screenshot from Google‘s AI answer to my question: "The VIC-20's character ROM, specifically the D880, can be replaced with a 2732 EPROM using a simple adapter. This adapter project allows for easy replacement of the original ROM without needing large EPROMs, jumpers, or SMD components. Here's how to replace the D880: 1. Obtain the necessary parts: You'll need a 2732 EPROM, an adapter PCB (available from PCBWay, according to PCBWay.), and a way to program the EPROM with the character ROM image. 2. Program the EPROM: Use the provided zip file from the project to program the EPROM with the VIC-20 character ROM image. 3. Install the adapter: Place the programmed EPROM into the adapter and then insert the adapter into the VIC-20's character ROM socket."
Just searched #Google for which transitors are suitable for replacing the 2SD880 at Q4 on a VIC-20CR board. That AI smarty suggest I should replace it with an EPROM. Brilliant! I have plenty of those! 🙄
Time to finally change my default search.
