MV1C Error

[Brendan1495]

Hi all, would anyone be able to help with this issue, I bought this from aliexpress last year for a project and made the mistake of not testing. I have just come to use it and I am getting a green screen with illegal instruction, done all the usual cleaning connectors etc and still the same. Any help would be appreciated thanks

What cartridge are you testing with? Do you have another to try?

I have a couple, the cartridges work fine on my open mvs

I would take this to @StevenK 's house as he's a real tech guru and he lives in England!
