a71c5946f0
Ensures proper manipulation of scan_statuses, leading to the correct result out of a CRTMachine.
...
Possibly with the exception of the TMS, as I appear to have uncovered an unrelated issue there.

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.

Adds composite monochrome output for the Oric. At least temporarily.

Restores RGB mode to the Oric. More thought required for composite.

Thomas Harte
5f90941e4e
Starts nudging the Oric back to functionality under the new regime.
...
i.e. one where it can't invent internal pixel formats.

Starts towards reintroducing the proper mechanisms for selecting a display type at runtime.

Starts to bend 'CRTMachine' to a world farther from owning the GPU relationship.

Corrects order of initialisation for the Typer and Oric video.

Standardises on const [Half]Cycles as the thing called and returned, rather than const [Half]Cycles & as it's explicitly defined to be only one int in size, so using a reference is overly weighty.
2017-07-27 22:05:29 -04:00
Thomas Harte
8361756dc4
Switched definitively to the works-for-now approach of requiring an explicit opt-in where somebody wants to clock a whole-cycle receiver from a half-cycle clock.
2017-07-27 07:40:02 -04:00
Thomas Harte
75d67ee770
Relocated ClockReceiver.hpp as it's a dependency for parts of the static analyser, and therefore needs to be distinct from the actual emulation parts.
2017-07-25 20:20:55 -04:00
Thomas Harte
a1e9a54765
Eliminated redundant uses of ClockReceiver and sought to ensure that proper run_fors are inherited all the way down.
2017-07-25 20:09:13 -04:00
Thomas Harte
6369138bd1
Converted the Oric's video output into a ClockReceiver.

Fixed Oric SCART mode by having it change what it's giving to the CRT based on which shader it knows will be active.
2016-12-10 13:55:56 -05:00
Thomas Harte
a549fd1ecc
Introduced the ability simply to piggy-back off the CRT's natural phase for the colour burst, thereby eliminating a couple of redundant independent attempts in the Oric and Electron.
2016-12-10 13:42:34 -05:00
Thomas Harte
6cdd41e5a9
Added direct use of the colour ROM, uploading 16 bits per pixel to contain the entire ROM composite wave.

Switched video to postfix underscores, for consistency.

Fixed inverse characters, added an extra per-frame phase change, based on empirical observation, ensured header guard won't become ambiguous.

Added in the missing keys; added variable phase to the video.

c9962f6502
Made an almost complete implementation of video. Just one row of the diagnostics cartridge seems to be off, showing thw wrong character set.
2016-10-13 19:34:29 -04:00
Thomas Harte
69920a4979
Made some basic first attempt at parsing video attributes; ensured lowest byte of ROM is readable.
2016-10-13 07:59:11 -04:00
Thomas Harte
120b2d9e33
Switched to using a diagnostic ROM for now, as it'll definitely boot without initially requiring either a 6522 or AY. Have some forms appearing which imply I'm not doing badly, at least up to not knowing where I'm supposed to get character pixels from.
2016-10-12 21:52:47 -04:00

304f0999cd
Made a faulty but hopefully creditable attempt to demarcate an Oric frame.
2016-10-12 21:29:21 -04:00
Thomas Harte

Added just enough wiring to add something that will generate the video, one day.
