FO 08:14 PM Feature #55 (New): Replace main CPU

I really find the stack based zpu annoying to debug. Also as its setup the rom is full.

FO 09:47 PM Bug #25: F10 Hard Reset Ignore inserted cartridge (Core v7)

This is the last thing remaining for V15. In order to do it (simply) I decided to allow off PBI access from turbo mode and zpu. That seems to work now, except its failing timing. I think I need to plumb the internal freezer in differentl... foft

FO 09:28 PM Feature #51: Debug port

I have a first cut of this building. This will be part of the v15 core.
Next I need to build the capture software to stream this into the PC. Then some post-analysis software, probably a hacked up emulator. foft
