Josh Dersch	0cce77c842	Fixed S register addressing (many things now working!), tweaked display (mouse displays correctly in lowres mode). Added support for committing disk changes back to disk images (done automatically when switching disks or exiting). Repaired BravoX image.	2015-12-22 15:45:56 -08:00
Josh Dersch	3c8a64bac8	Ethernet implemented, fixed a bug in "mixed" double word stores (store followed by fetch rather than two stores). Fixed a few UI issues, fixed Reset behavior.	2015-12-17 16:11:03 -08:00
Josh Dersch	115432516f	Refactored drive logic (mostly) to allow for multiple drives. Fixed drive selection logic. Started work on "real" UI.	2015-12-11 16:57:02 -08:00
Josh Dersch	f256042cf4	Small tweaks, draft of annotated XMesa microcode assembly added.	2015-11-24 17:27:06 -08:00
Josh Dersch	b13944c81c	Implemented proper video timing, basic mouse support and fixed microcode RAM loading. MARTEST now passes with flying colors; more things are running. Suspect disk timing for other failures.	2015-11-19 17:41:16 -08:00
Josh Dersch	cbcfd2b47e	Minor bugfixes, introduced a new timing infrastructure and moved DiskController over to it. Minor performance improvements; now running at 110% speed. Display timing is still too slow.	2015-11-17 16:09:50 -08:00
Josh Dersch	03661fc90b	Fixed display microcode and display controller. Alto display now generated 100% by microcode tasks. A few small optimizations.	2015-11-16 16:46:24 -08:00
Josh Dersch	47a2ee4b2b	Implemented temporary "fake" display controller which renders Alto DCBs to the screen, bypassing the display microcode. Alto is booting! Rough keyboard implementation.	2015-11-11 16:34:44 -08:00
Josh Dersch	ca638f1d6e	Initial rough implementation of Display hardware and associated tasks. Not really working.	2015-11-10 17:04:05 -08:00
Josh Dersch	e1c90dbe01	Fixed bug in carry flag on SUB operations; SUBLZ X,X now works correctly. Alto now appears to boot successfully. Skeleton of Display hardware added.	2015-11-09 17:36:26 -08:00
