Thomas Harte

2f53b105bb The Enterprise is now an Activity::Source; also sketches out the owner of Dave's timed interrupt logic. 2021-06-27 21:02:04 -04:00
Thomas Harte
be19fa9dde This mapping needs to know where it will occur. 2021-06-27 17:30:09 -04:00
Thomas Harte
81e9ba5608 This is correct from the Enterprise's side of things, I think. 
I just need to complete the missing part of JustInTimeActor. After I do some empirical testing of this.
 2021-06-27 17:24:21 -04:00

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?

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

e5e988b28f Adds an incorrect assumed-pixel-mode serialiser. 
This actually shows something a bit like the Enterprise boot logo.

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.
