Well I got a EPROM burner and rigged it work on the 2364 rom I pulled. I see 8 bytes that don't match the ROM images I find on the internet. I put my read image in an emulator and it never boots. The live memory map shows it stuck in a bootloop at about the same rhythm I am seeing on the scope. I think I am on the right path 🤞

It verily appears to me that you're outputting with the horizontal & vertical transposed!
Well I got some 27c64's.. it at least does /something/ now 😆
