Quit a few months - once the CPU and basic chips are hacked together, there's still the whole DM270 shemozzle, virtual HDD...
progress: 'Vimp' has been approved as a sourceforge project. Fixed a CPU bug that was causing the emulator to crash, but this has unearthed at least 2 more issues. Added a 'run till method call' button that makes it very easy to charge through code.
If anyone can tell me if what instructions I need to invert the carry flag on I'd be grateful - just SUB and CMP or the whole lot?
edit: Put what memory mapping I've done on
