Thomas Harte	b59da7d4bc	Added some documentation.	2016-10-19 22:47:44 -04:00
Thomas Harte	08275c6241	Fixed mixer IO bit usage.	2016-10-19 22:22:15 -04:00
Thomas Harte	59162228ef	Reduced mask for clarity.	2016-10-19 22:14:05 -04:00
Thomas Harte	319d7c2b12	Fixed premature wrapping of the envelope, played about with whether that should be subject to a predivision by 256. It feels unlikely?	2016-10-19 22:12:51 -04:00
Thomas Harte	6073906c39	Commented and fixed mistake that would equate any noise divider > 32768 with 0.	2016-10-19 21:51:35 -04:00
Thomas Harte	101f168ea4	Made an attempt to tidy up.	2016-10-19 21:43:18 -04:00
Thomas Harte	ada37abe23	Made an attempt to implement noise and envelopes. Not quite right yet.	2016-10-19 21:13:22 -04:00
Thomas Harte	bd6e6674a0	Fixed signed shift assumption and noise-related register test.	2016-10-18 22:20:12 -04:00
Thomas Harte	9669a5ec9b	Switched to a more authentic interfacing to the AY.	2016-10-18 19:32:15 -04:00
Thomas Harte	43612e1ca2	Made an attempt to eliminate conditionals (running before I can walk?) and started edging towards an envelope generator.	2016-10-17 08:03:38 -04:00
Thomas Harte	9730e8247f	Ensured propagation of synchronise messages, added enough to do plain tone. Probably. So: noise and envelopes missing. And it's all far too quiet.	2016-10-15 21:04:21 -04:00
Thomas Harte	51bdac27ae	Made some AY advances; it's now being polled for samples and collecting more information on what it needs to output.	2016-10-15 17:45:39 -04:00
Thomas Harte	288d10c253	Got some keyboard reaction.	2016-10-14 21:44:15 -04:00
Thomas Harte	138eabcff4	Continued in my effort to wire up a keyboard. Will need further to continue.	2016-10-14 21:35:15 -04:00
Thomas Harte	d8e4c488c2	Started iterating towards having an AY and a fully-working keyboard.	2016-10-14 21:18:03 -04:00
