From the project
SCOPETREX vector gaming on your oscilloscope!
Update 21-August-2024: I learned that the IRQ line on the 65C22 wasn't connected, so I fixed that. See the section at the bottom for details, or just fab with the latest files and don't worry about it.
Have you ever wanted to buy a Vectrex, but you can't afford the high prices on auction sites? Do you already have a hoard of Vectrexes, but want another one? Well now you can build your own!
