a15af1df5e Attempts to use the other bit of disk drive control, the 5.25"/3.5" select. 
For the record, the ROM thinks it finds some Smartport devices and then attempts to talk to them. Since none is present, it blocks forever.

b3ab9fff9b Imports a custom-built copy of Klaus Dormann's 65C02 test, with only 65816-compatible parts. 
Thereby fixes another couple of 65816 issues — BRK(, etc) not clearing the decimal flag, and `TRB d` being mismapped.
 2020-10-19 19:27:16 -04:00
Thomas Harte
99eba2f8ba Ensures intended 65816 exception behaviour. 
i.e. the relevant micro-op sequence exists, and its operation isn't lost. Also sets the 65816 by default to jump straight into power-on, not to execute an instruction first. That shouldn't make a functional difference, but it makes debugging easier because it makes startup fully deterministic.
 2020-10-18 14:43:47 -04:00
Thomas Harte
b22aa5d699 Starts transcribing the addressing examples I have into tests.

525233e10b Ensures all input data types are parseable in Metal.

df89a8771c Makes an attempt to have the emulator fill the actual GPU buffers. 
Not that they're drawn from correctly yet. I might first take a run at a new quick-path output route for emulated RGB displays, that just seeks to use the scans directly. No intermediate buffers. Besides probably being a good feature, it'll be a good way to ramp further up with Metal.

Thomas Harte
ead32fb6b2 Return to old behaviour if --logical-keyboard isn't specified. 
This is at least until I'm more confident in the keypress/text input merging. Also, switches to a vector for intermediate keypresses, to ensure order is retained even if timestamps are absent.

Thomas Harte
b76a5870b3 Moves drawing into the next timer tick after retrace if sync locked. 
... which should mean it occurs within 1/600th of a second of announced retrace, which I assume always will be less than the retrace period. So: does the frame buffer update during retrace.

This should completely eliminate tearing for machines that can be synced to the native output rate.
 2020-02-08 18:07:13 -05:00
Thomas Harte
7c0f3bb237 Gets to slightly adjusting execution speed and matching up respective vertical syncs.

d97a073d1b Adds the necessary routine for all machines to be able to respond to get_scan_status. 
They all just as the CRT, as all are currently based on the CRT. Which doesn't currently know the total clock rate it would need to in order properly to scale the answer to the question. Further thought coming.

I'm not necessarily happy with the idea of just shoving in a [pseudo-]random number generator in rather than emulating the proper process underneath, but for now I throw my arms up.

b8a1553368 Adds putative support for PlusToo-style BIN files. 
Albeit a bit of a guess, since it's not intended to be an emulator file format.

Thomas Harte
3e9fa63799 Adds a receiver for drive-motor control bytes. 
My new belief is that I'm either reading the buffer from the wrong place, or the 68000 isn't filling it for some reason.

6d985866ee All proper inputs are now provided to the audio generator. 
Hopefully. The next job is to generate audio. If that sounds correct, then the disk motor speed question can be tackled.

Thomas Harte
723137c0d4 With some time additions to the 6522, starts wiring in Macintosh audio. 
The audio buffer is also the disk motor buffer, so this is preparatory to further disk work.

254132b83d Eliminates 6522Base in pursuit of working handshake modes. 
Specifically: this means that the places from which the BusHandler may be called are more numerous.

Thomas Harte
68392ce6f5 Adds enough of a concept of Mac video to get a properly initialised display. 
Completely empty at present, naturally. Also this is the very first time I've run my 68000 at live speed. From just one data point, it's not terrible. Phew!

Thomas Harte
52e33e861c Starts to introduce the QL as a second source for 68000 testing. 
It's advantageous over the ST in that a commented disassembly of the ROM is available.

f9101de956 This might very well be the 68000's first real gasp: performing an ABCD. 2019-03-14 19:32:15 -04:00

Thomas Harte
86a6b04d4a Begins attempts to keep track of display metrics. 
i.e. a system that can both make smart decisions about when to use a lower resolution, and hopefully allow some sort of flywheel-esque horizontal retrace synchronisation. And possibly some raster beam chasing?
