60bb9bfd13 Added "-rompath" startup option to allow specifying an alternate path for microcode ROMs. Updated raw Ethernet handling to work with ncap (which replaces WinPcap since it's no longer being updated) running in WinPcap mode. Fixed bug with DebuggerPrompt -- when run with stdin/out redirected, Console.Width is 0, resulting in a div/zero issue. 2019-02-21 16:43:44 -08:00

d96d232fd3 Initial commit of changes for 1.2.3. This includes:
- Scripting support: Allows for recording and playback of mouse/keyboard input and various system control actions.  Simple (i.e. basic) scripting format.

- Fix for stale packets left in ethernet input queue; packets received by pcap while Alto's receiver is off are discarded.

- Mouse input made more accurate, and tweaked to avoid Alto microcode bug that causes erroneous mouse inputs under very rare circumstances on real hardware, but much more frequently under emulation.

- Small code cleanup here and there.  Moved many UI strings to resources, many more to go.

38124350fb Fixed Trident drive select issues, corrected issue with extended memory bank registers. IFS now runs. 2017-08-31 12:23:46 -07:00

523a4bb27f Initial implementation of Trident controller and drives (supporting T-80 and T-300 packs). TFU works and can certify, erase, exercise and manipulate files on Trident packs. TriEx doesn't quite work properly yet. Still some issues to iron out.
Added file-backed disk image implementation for use with Trident disk images, did some basic refactoring of disk load/unload logic, added support for creating new (empty) disk images for both Trident and Diablo disks.

Added UI for loading/unloading/creating up to 8 trident packs; added blank Diablo pack creation UI.  (Both Windows and *nix interfaces.)

Added configuration support for same (both Windows and *nix.)

Small correction to Print output path browsing logic.

Fixed Windows installer, now places the right ROMs for Alto I configurations in the right place.

Fixed issue when starting up with corrupted configuration.  Corrupted configuration is ignored and ContrAlto will run with default config.

f849b795a6 - Fixed two memory state machine issues:
1) The Orbit microcode occasionally expects to be able to do a double-word read in cycles 6 and 7 instead of the usual 5 and 6.
  2) The double-word logic incorrectly handles several species of overlapped read/writes, which Spruce's layout microcode uses.

As a result, Spruce now works, as do the Smalltalk-80 images.

Several tweaks to microcode disassembly (still rough).

Completed Orbit / Dover ROS / Dover Print Engine emulation.  Still some rough edges; it works and can create PDF output.

Tweaked Disk Controller's Restore operation, it is now more accurate though wasn't causing any noticable issues.

c671b04ee8 Switched from PCap.net to SharpPcap for ethernet encapsulation; SharpPcap is cross-platform, this allows raw ethernet encapsulation to work on Linux and OS X. 2017-06-13 11:19:25 -07:00

6cadb08b0e Added support for Unix/OS X using Mono. This uses SDL2 for display, keyboard, and mouse. 2017-06-07 11:18:32 -07:00

4bc85daa36 New hardware implementation:
- Orbit controller: implemented and passes ROS-less diagnostics
- ROS: In progress, not functional
- DAC: For Ted Kaehler's Smalltalk Music system (FM and Sampling).  Works, generates audio and can capture to WAV file.
- Organ keybard: Stub, enough implemented to make the music system happy (so it will play back music and not crash.)

Some minor cleanup.

New dependency on NAudio package for DAC playback.  Installer updated to include NAudio lib.

50f4f9e7a1 Minor fixes, modified Ethernet to send packets as broadcasts, to match with IFS changes. 2016-12-15 14:08:39 -08:00

5580a8a7a8 Changed settings storage to use the settings framework rather than rolling my own; this makes per-user settings work and fixes permission issues for non-admin users. Also made a small tweak to make the mouse work properly in high-dpi scenarios. 2016-07-18 17:28:10 -07:00

5a17e7cfac Added GPL license header to source code; updated readme; removed disk images from installer package. Removed pcap folder from project 2016-07-12 17:18:54 -07:00

6429c3ae7a General code cleanup. Fixed debugger display of RAM banks for 3K systems, cleaned up logic for displaying ucode memory. Implemented memory timing for Alto I systems, incorporated Alto I uCode ROMs from Al K, which now boot. ST-74 runs better now. 2016-05-05 18:56:29 -07:00

a62ac823ed Initial implementation of Alto I support. Still need proper Constants ROM for Alto I. Changed IDISP to use ACSOURCE ROM (small perf increase). 2016-04-13 15:45:33 -07:00

c48e530cbe Finished up configuration UI. Config is now persisted to a configuration file. Small fixes to UDP encapsulation to ignore packets coming from the same host. Small fix for PInvoke for high res timer. 2016-03-02 17:31:19 -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
