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.

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

This actually shows something a bit like the Enterprise boot logo.
 2021-06-15 22:31:50 -04:00
Thomas Harte

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
