c331d15429 Makes space to allow for 64kb EXOS ROMs. 
I think some of the later ROMs have a more thorough memory test, which might provide better detail on whatever's going on here.

Thomas Harte
4414e96710 Adds enough text mode for now.

Thomas Harte
606c7709cf Shims in enough to get the Z80 to run perpetually. 
Notably I don't actually currently know how the interrupt registers work, but getting some sort of display running might be the first order of business.
 2021-06-14 22:28:31 -04:00
Thomas Harte

 2021-06-14 21:45:12 -04:00

Thomas Harte
5acd97c860 Puts enough in place for a GUI-led installation process. 
... and provides a lot of the Objective-C wiring necessary to expose that to Swift.
 2021-06-06 14:24:38 -04:00

Thomas Harte
0ebd900e40 Baby steps: apply Z80 state. 
As far as it currently is. Since SNA is leaving the PC at the default of 0x0000, this currently has no visible effect.
 2021-04-25 13:03:24 -04:00
Thomas Harte
cc78bfb229 Forwards most of the Z80 state. 2021-04-25 13:00:43 -04:00
Thomas Harte
d61f478a39 Basic sketch for state snapshots: an extra field on Target. 
I think it doesn't make sense for states to own a target as that complicates the concept of Media. Plus they're distinct because it makes sense to have only one per Target. Let's see how this pans out.
