325a416b87 Cleaned up EthernetController, moved compilation back to "Any CPU" (preferring x86) using x86 versions of the PcapDotNet libraries, netting a 10-20% speedup. 2016-01-19 14:15:20 -08:00

8463ef19d0 Ethernet! A really hacky version of Ethernet. Can play MazeWar, but still needs work. 2016-01-15 14:44:24 -08:00
Josh Dersch
898abdc906 Minor fixes for debugger interface and disassembler; started hooking Ethernet interface up to real host Ethernet (because MazeWar.) 2016-01-12 17:29:42 -08:00

30ed445764 Fix for soft-reset emulator uPC and device reset; CopyDisk now executes correctly. 2016-01-11 16:16:05 -08:00
Josh Dersch
8361f287e3 Added Parity Task (for completeness' sake), fixed SWMODE bank switching logic for 2K ROM, minor tweaks. 2016-01-07 10:34:10 -08:00

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
42947488e9 Cleaned up new UI, refactored Debugger/control logic, fixed mouse capture behavior and started working on better keyboard input. 2015-12-14 17:47:12 -08:00

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
2c2ea68a63 Implemented disk writes (roughly). Bravo now works. DIEX passes with writes enabled. Begun investigation into drive selection logic. Added Mesa source code with annotation, is displayed in ROM1 tab. 2015-12-02 12:39:10 -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

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
Josh Dersch
2918ede7ce Some fixes to emulator task dispatch functions, added Nova disassembler, nova instruction single-step and nova instruction breakpoint support. Penciled in DNS (Nova Shift) support in emulator task. Added skeleton for Logging. 2015-10-28 14:11:04 -07:00
Josh Dersch
