9a0022cfcb Removes temporary work. 2021-06-18 18:44:07 -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?

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.

4414e96710 Adds enough text mode for now.
Discovered: a memory fault is being reported at startup.

7161783a4f Adds lpixel output. 2021-06-16 21:16:26 -04:00

cbac48da86 Attempts full run at pixel mode. 2021-06-16 20:43:22 -04:00

d9142d5427 Adjusts declared scale, accurately to communicate pixel clock. 2021-06-15 22:39:44 -04:00

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

e94e051c87 Adds an allocator for pixels. 2021-06-15 22:03:41 -04:00

5fc91effb5 Corrects top border. 2021-06-15 21:48:11 -04:00
Thomas Harte
6c9dacbe89 Stabilises display, albeit that top border mode now appears to be off. 2021-06-15 21:31:07 -04:00

6a7eb832cc Introduces almost-stable block-level frame generation. 2021-06-15 20:55:58 -04:00
Thomas Harte
60cf8486bb Makes a genuine attempt at real line counting.
No output yet though.

90b8163d54 Add exposition. 2021-06-15 17:44:39 -04:00

a1e4389f63 Give Nick some RAM to inspect and just enough sense to know when it should reload its line parameter table. 2021-06-15 17:43:13 -04:00

440b11708b Adds an unused CRT. 2021-06-14 23:11:48 -04:00

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.

1d1e6d1820 Adds a shell of a Nick. 2021-06-14 22:19:25 -04:00
Thomas Harte
3eb4dd74a2 Exposes memory control.
Machine now runs as far as trying to interact with Nick.

853914480c Revised guess; there's a jump to C02E almost immediately. 2021-06-14 21:40:19 -04:00

2a2ac1227b Makes first attempt at giving the Z80 something to do. 2021-06-14 21:29:56 -04:00

196c4dcdd9 Adds an appropriate ROM request. 2021-06-14 21:17:09 -04:00

c5a86f0ef7 Add Enterprise parts of the static analyser. 2021-06-14 21:11:06 -04:00

5f7b3ae313 Adds bare minimum to get a non-functional machine. 2021-06-14 21:02:40 -04:00
Thomas Harte
61c127ed2e Adds Enterprise as a File -> New... machine.
And, similarly, exposes it for the route used by SDL.
