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

311ddfb05a Add note to self for tomorrow. 2021-06-17 22:34:52 -04:00

2fd8a8aa66 Begins addition of interrupt feedback from Nick. 
Also fixes clock rate. Though clearly get_next_sequence_point isn't quite right yet.

0c3e9dca28 Adds some basic keyboard inputs. 
I think the next thing required is interrupts though.

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.
