  • Thank you! this was perfect for my breadbin that had both kernal and caracter rom go bad and the usual 2327 adapters didnt fit next to eachother. One question tho, what is A12 for? thanks

    The Character rom is 4KB, but the kernal is 8KB, for stablizing character rom eprom A12 you need pull down or up . The sample CHR ROM file is double all, like AA,BB,CC,DD... the kernal sample is A,B,C,D... You just use 10K A12 resistance but there is no need A12 switching for the sample rom files. I hope I could explain via my poor English. Thank you very much.

    Ok they work well without any jumper on A12, i was just curious :) Any chance you can make pcb files available for this? i would like to add a third socket for basic rom ( or one for only basic and kernal ) so i dont have to use risers and a seperate adapter board for that. see here, it hits keyboard :) https://imgur.com/a/f9nFmx8
