Adds activity indicators for the BD-500 and Jasmin.
...
Also slightly cleans up DiskController a little further.
2020-01-15 23:39:15 -05:00
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
Thomas Harte

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
Thomas Harte
7361e7ec34
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

This should fix Turrican due to the latter change; I'm not aware of software that uses the former.

Switches to latching video interrupts until acknowledged.

Seems to fix Cisco Heat, at least. I have no idea whether I'm latching the correct thing, whether IACK should clear both or only one, etc.

Rejigs the video stream to ensure shifter really is continuous.
...
... and definitively to avoid potential buffer overruns. Or, at least, to have a mechanism in place definitively to avoid them. Which will be tested and debugged as necessary.
Also simplifies the colour burst and border/pixels selection logic.
2019-12-27 22:47:34 -05:00
Thomas Harte

Either: (i) 263 is incorrect; or (ii) my logic as to frame height is incorrect. Given that the horizontal side of things is really well documented, I'm currently guessing (i). Research to do.

Corrects accidental dropping of pixel residue.
...
Specific issue: the repeated (start_column != end_column) test, which can no longer be correct if start_column has been incremented in the (x_&7) test.
The visible effect was to omit pixels from the output wave, which also affected observed sync timing.
