9be23ecc34 Add end-of-Blit interrupt. 
Along with a slightly easier path for posting interrupts, in C++ compilation unit terms.

5ccb512883 Moves the CIAs into the Chipset class. 
This reflects the routing of interrupt signals for now, but also prepares for the addition of disk drives.

a4263b5a8c Ties bitplane collection to line position. 
Outgoing bug: incrementing the video relative offset too often, due to cycles that are discovered to be CPU-targetted.

fd70f7ad43 Attempts to make pixel content observeable. 2021-09-08 20:57:26 -04:00
Thomas Harte
6e034c9b7f At least manages to place a pixel region on screen. 
Albeit that I've suddenly realised that I've failed properly to think about high-res versus low-res.

dda154c7c6 Adds nonsense disk reads, which seems to lead to bitplane and blitter requests. 
Progress, at last!

9215535bee Adds a container for the disk controller. 
Thereby appears to prove that my Amiga is getting as far as attempting to load from floppy.

3544746934 Modifies interface, starts on scheduler. 
Probably corrects the pixel clock, which I think was scaled up by a factor of 4.
