Thomas Harte
b49cc407c6 Adds some guesses as to the EXDos expansion.

Thomas Harte
d8b9cdf7a2 Correct multiplier. 2021-06-20 14:25:37 -04:00
Thomas Harte
09dbff39f2 Also map keypad to F keys. 
This is a pragmatic and arguably Apple-centric decision. But also it's fairly arbitrary, as the Enterprise doesn't have a number pad.

Thomas Harte
fbf1adef05 Introduces unit test and thereby seemingly fixes get_next_sequence_point. 
There's still improper output in the actual machine though, so maybe something else is afoot?
 2021-06-18 17:44:17 -04:00
Thomas Harte
311ddfb05a Add note to self for tomorrow. 2021-06-17 22:34:52 -04:00
Thomas Harte
2fd8a8aa66 Begins addition of interrupt feedback from Nick. 
Also fixes clock rate. Though clearly get_next_sequence_point isn't quite right yet.
 2021-06-17 22:30:24 -04:00
Thomas Harte
0c3e9dca28 Adds some basic keyboard inputs. 
I think the next thing required is interrupts though.
 2021-06-17 20:47:56 -04:00
Thomas Harte
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.
 2021-06-16 22:25:00 -04:00
Thomas Harte
4414e96710 Adds enough text mode for now. 
Discovered: a memory fault is being reported at startup.
 2021-06-16 21:42:20 -04:00
Thomas Harte
7161783a4f Adds lpixel output. 2021-06-16 21:16:26 -04:00

Thomas Harte
e5e988b28f Adds an incorrect assumed-pixel-mode serialiser. 
This actually shows something a bit like the Enterprise boot logo.
 2021-06-15 22:31:50 -04:00
Thomas Harte
e94e051c87 Adds an allocator for pixels. 2021-06-15 22:03:41 -04:00

Thomas Harte
440b11708b Adds an unused CRT. 2021-06-14 23:11:48 -04:00
Thomas Harte
f90dce5c54 Take a guess at Nick timing. 2021-06-14 22:56:26 -04:00
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
1d1e6d1820 Adds a shell of a Nick. 2021-06-14 22:19:25 -04:00
Thomas Harte

Machine now runs as far as trying to interact with Nick.
 2021-06-14 21:45:12 -04:00
Thomas Harte
853914480c Revised guess; there's a jump to C02E almost immediately. 2021-06-14 21:40:19 -04:00

And, similarly, exposes it for the route used by SDL.
 2021-06-14 20:55:39 -04:00
Thomas Harte

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

 2021-06-04 18:54:50 -04:00
Thomas Harte

... and with error reporting currently AWOL.
 2021-06-03 22:22:56 -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.

Thomas Harte
2510064218 Completes state object.

Thomas Harte
a5098a60ec Attempts to get in-SNA software to start. 2021-04-25 13:18:26 -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.
 2021-04-24 23:17:47 -04:00
