0182b0483a Added a 'power on' flag that is set automatically at construction but can be declined. Saves all that stuff of every machine having to set and then unset the RST line, and fixes an Electron bug related to that. 2016-06-29 19:13:24 -04:00

bff53775ad Update README.md 
Corrected typo and resulting logical error; it's definitely 227.5 subcarrier cycles per line, NTSC fans!
 2016-06-29 11:12:03 -04:00
Thomas Harte
6419d9c485 Added a single IRQ test case, discovering that I'm two cycles short. Whoops! 2016-06-28 21:29:43 -04:00
Thomas Harte
6e698e908e Made an attempt to reduce cost of the most-likely path. 2016-06-28 18:46:00 -04:00

 2016-06-27 22:06:26 -04:00
Thomas Harte
574aa32b72 Made an attempt to implement NMI. Some work to do on the B flag though, I think. 2016-06-27 22:01:48 -04:00

Thomas Harte
d5e50f5ea0 Got a bit more explicit about how ports are identified on the 6522. 2016-06-26 12:30:01 -04:00
Thomas Harte
8d9eb30d82 So it sounds like the user-port VIA might actually be connected to NMI? 2016-06-25 16:31:35 -04:00
Thomas Harte
8741be5c84 Made the slightest possible effort to get TAPs opened and passed to the VIC. 2016-06-25 16:24:52 -04:00

Thomas Harte
2bd71e7e9b .reset is the more normal way to reassign a unique_ptr. 2016-06-23 20:52:44 -04:00

e05003c176 Discovered that the VIC and the VIAs can be simultaneously selected. Adjusted bus appropriately. 2016-06-22 17:34:42 -04:00
Thomas Harte
b753690d5e Made an attempt to adjust the 6560 to a model compatible with that advocated by the available documentation. Exact decision timing may need further work. 2016-06-21 22:12:01 -04:00
Thomas Harte

Thomas Harte
31b26b8118 Made a first attempt to implement the full top-to-bottom change of clock rates, giving the Atari the ability to change rate when it switches to PAL mode, as it should always have been. 2016-06-20 21:47:27 -04:00
Thomas Harte
3591479571 Fixed mismatch between initial tick box states and communicated switches; ensured they're visible upon launching a game. 2016-06-20 21:31:07 -04:00
