f4db4c3a73 Implements ROM::Request::validate. 
It now also validates ROM sizes, so can no longer take a const Map.
 2021-06-04 18:54:50 -04:00
Thomas Harte
a30eeaab6a Starts to introduce a new grammar for ROM requests. 
They can be optional, and chained together in AND or OR combinations. A central catalogue knows the definitions of all ROMs.

a5098a60ec Attempts to get in-SNA software to start. 2021-04-25 13:18:26 -04:00

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
349b9ce502 Don't post contended accesses other than on the +2a/+3. 
Those machines have an actual latch for this stuff, the others don't.

d77ddaf4fa Switches the Electron to JustInTimeActor video. 
Also reorders template parameters; I think that specifying a different time base is likely to be more common than using a divider.

14663bd06b I think 3 is what I'm aiming for here. 
But this probably isn't correct for IO cycles.

465c74ab86 Adds the Spectrum side of typing. 
The character mapper itself needs some Spectrum logic.
