MESS emulator
Posted: Wed Sep 15, 2010 12:54 pm
One of the 6809E based machines listed for MESS is a 'Dragon 64 Plus'. Can anyone explain how this 'Dragon 64 Plus' is different from a standard Dragon 64?

Thanks for the info. How do you access the extra 64K of RAM from machine code?prime wrote:Yep, currently emulates just the extra ram, at some point I do want to try and get it to emulate the 80 col too.
