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.

Thomas Harte
388d808536 Switches to providing UDS and LDS implicitly via address. 
Also makes sure that the difference between a non-data cycle that starts without the address strobe active and one that starts with it active can be discerned.
 2019-03-16 17:54:58 -04:00
Thomas Harte
720aba3f2d Adds an implementation of SBCD and slightly neatens syntax for building programs. 2019-03-14 21:22:02 -04:00
Thomas Harte
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?
 2019-03-04 21:54:50 -05:00

bee0d09877 Splits display update and draw functions. 
On the Mac, draw is now called without an update for resizing events, and
anything else requested by AppKit. In all other cases — including from
the SDL version — both are called as if they were still a single function.

... for all input data types.
 2018-11-22 17:20:31 -05:00
Thomas Harte

Thomas Harte
75bc0e451d Reintroduces the accumulation texture. 
Disables automatic clearing of the texture target, as the profiler indicates the vector instantiation to be a huge time sink.
 2018-11-18 21:39:11 -05:00
Thomas Harte
8a699b6072 Kills setup_output definitively, saving some indirection. set_scan_target takes its place. 2018-11-14 21:52:57 -05:00

Thomas Harte
dce52d740d Finally gets some pixels back on screen. 
For now, just the raw scans, direct to the framebuffer, with no intermediate processing. But it seems to prove that at least some of the proper data is reaching the GPU.
 2018-11-11 23:23:42 -05:00

Let's see!
 2018-11-03 23:40:39 -04:00
Thomas Harte
b40211d2c0 Starts to bend 'CRTMachine' to a world farther from owning the GPU relationship. 2018-11-03 21:54:25 -04:00
Thomas Harte
da4d883321 Adds first, incomplete attempts to talk to a ScanTarget from the CRT. 
Does away with the hassle of `unsigned` while I'm here; that was a schoolboy error.
 2018-11-03 19:58:44 -04:00
Thomas Harte
a8645f80bf Introduces 'non-exclusive' emulator-space keyboards. 
i.e. sets of keys that don't amount to an entire keyboard in the modern sense. Experimentally used by the Master System for its reset key.
 2018-10-24 21:59:30 -04:00

C.W. Betts
05d4274019 Remove LSItemContentTypes: they should be unique identifiers, not generic types like public.item or public.data. 
This can result in strange icons showing up in the wrong places.

Also added a category type.
 2018-09-07 16:39:52 -06:00
