Fixed: individual audio generators now either are or are not stereo. The speaker acts accordingly.

All these 'override's can be 'final's.
...
At least for the purpose of being communicative. I doubt there's much to gain in terms of compiler output — the DiskImageHolder can avoid some virtual lookups but nothing else leaps out.

In all these instances, final => override. So no need to repeat myself.

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.
2020-01-21 22:28:25 -05:00

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 suspect this is very temporary, but here it is.

Adds activity indicators for the BD-500 and Jasmin.
...
Also slightly cleans up DiskController a little further.

Thomas Harte
91fae86e73
Factors out paging, implements a bit more of the BD500.
...
That is, enough seemingly fully to work, if I force the drive to report ready.
2020-01-15 23:15:39 -05:00

Makes Jasmin autoboot optional, adds a Jasmin reset key, adds the Jasmin to File -> New... .
...
Also finally implements KeyNMI.
2020-01-05 21:57:33 -05:00

Fixed: the issue was failing to propagate motor control.
...
Also it seems to be incorrect to have the Jasmin paged at initial boot.
2020-01-05 21:35:20 -05:00
Thomas Harte
533729638c
It seems like Jasmin paged in at boot, and button = page back in and reset works?
...
At least, that gets me a 'boot failed' error. Which is something.
2020-01-05 20:34:15 -05:00
Thomas Harte
9f30be1c13
Attempts to implement most of a Jasmin disk interface.
...
With one obvious omission: there's no way to start it? The real interface had a dedicated button, but I don't yet know what that button did. Research needed.

Standardises on read and write for bus accesses.

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.

Introduces a new scan source data type, motivated by the reasoning used by the Oric.
...
Specifically: it'll allow PCM sampling of the potentially arbitrary composite generation logic of various machines.

Starts to expand the range of supported 6502s.
...
This fully implements the NES 6502 because, well, it's virtually no extra work, and ensures that RDY takes effect on write cycles on 65C02s.

7b7beb13a3
Eliminates the fiction of setting and getting registers.
...
The Disk II seems lower level than that; it will read the data bus whenever it likes, it is the programmer's responsibility to keep up with that. It also reserves the right not to load the bus regardless of whether it receives a read or write access.
