  • 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 Updated raw Ethernet handling to work with ncap (which replaces WinPcap since it's no longer being updated) running in WinPcap mode.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. master Josh Dersch 2019-02-21 16:43:44 -08:00

  • 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. Josh Dersch 2017-08-22 13:18:31 -07:00
  • bfcce44a8f Fix for Ethernet bug introduced with switch to SharpPcap: Filtering of packets sent by ourselves doesn't actually take place. Amazingly this didn't break much, but Trek was affected and we can't have that. Josh Dersch 2017-07-11 11:25:02 -07:00
  • 1abb1db4d3 Updated readme files. Josh Dersch 2017-07-10 17:09:26 -07:00
  • 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. v1.2.1 Josh Dersch 2017-07-10 16:49:12 -07:00
  • 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. Josh Dersch 2017-06-13 11:19:25 -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.)
