Odd question for you. I've been playing around with the Dragon's cartridge connector lately and have got some cool stuff working, but I've not yet managed to return a number when the Dragon accesses $C000.

Anyway, something that's been bothering me here is why does PEEK() across the entire cartridge memory space always return 126 if there's not a working cartridge connected? I can interfere with that, but there's clearly a gap in my knowledge somewhere which explains why that happens.

Cheers.

That is explained here.

Hmm. Weird.

Cheers mate.
