Thomas Harte	8a2bdb8d22	Converted the TimedEventLoop and the things that sit atop it into ClockReceivers.	2017-07-24 21:19:05 -04:00
Thomas Harte	83628b285b	Experimentally turned the 6502 into a clock receiver. No problem encountered.	2017-07-22 21:52:21 -04:00
Thomas Harte	f931cd582d	Switched to use of std::vector in those few remaining places where I was still using a unique_ptr to a native type and newing for myself. So, some of my earliest bits of code.	2017-07-16 13:54:07 -04:00
Thomas Harte	0808e9b6fb	Pulled the 6502 into a CPU namespace, making it an instance of something that has micro-opcodes and schedules them, and factoring out the formulation of a register pair.	2017-05-14 22:08:15 -04:00
Thomas Harte	e01f3f06c8	Completed curly bracket movement.	2017-03-26 14:34:47 -04:00
Thomas Harte	063a62372f	The Commodore serial bus and C1540 are now postfix underscorers.	2016-12-03 13:14:03 -05:00
Thomas Harte	4fab794747	Added a direct-to-two-cycles emulation path for 6522 owners.	2016-10-27 21:13:25 -04:00
Thomas Harte	6292ac5b26	Yet more .hpp clean(s)ing.	2016-10-20 21:15:21 -04:00
Thomas Harte	572d5587d9	Made a first stab at enabling multi-disk machines and thereby obeying (some of) the Plus 3's status register.	2016-09-25 21:24:16 -04:00
Thomas Harte	9bbcbd1001	Renamed class, intending to turn a Disk::Drive into literally just that, and have a thing with a PLL that consumes events be a Controller.	2016-09-25 20:05:56 -04:00
Thomas Harte	56c0d70c1f	Gave disks their own namespace.	2016-08-27 17:15:09 -04:00
Thomas Harte	d832e5e10d	Reduced 1540 PLL to running at 4Mhz. Which is possibly correct (?) Made minor change to avoid divide if possible.	2016-08-02 21:28:50 -04:00
Thomas Harte	bc10b3ee9a	It appears the problem is as simple as sectors being counted from zero.	2016-08-01 10:08:38 -04:00
Thomas Harte	f5e4ea3351	Some minor tidying, lots more of the caveman stuff as I try to determine what I'm doing wrong.	2016-08-01 09:43:08 -04:00
Thomas Harte	b43a7381ae	Fixed framing and first-byte-after-sync signalling. Hacked together as parts of it are, loading now appears to work!	2016-08-01 04:25:11 -04:00
Thomas Harte	41893b5ef6	Put in the absolute minimum logic for drive motor emulation. Drive appears to be attempting head steps.	2016-07-31 19:38:51 -04:00
Thomas Harte	740ea0b7e2	Added overflow-flag setting logic and ensured disk ROM gets through regardless of ROM/disk installation order.	2016-07-31 19:33:18 -04:00
Thomas Harte	0945049cd3	Made attempt to connect sync detect and then apply appropriate windowing, posting bytes to the appropriate place.	2016-07-31 18:29:44 -04:00
Thomas Harte	198fbbedc7	Reeled back all appropriate pieces of caveman debugging.	2016-07-31 13:42:34 -04:00
Thomas Harte	2332f72875	Formalised clock-rate multiplication within disk drives, discovered that the stepper didn't have ideal behaviour for my timed event loop and hence nailed down the semantics a ilttle more. ... (obiter: the 1540 now appears to discern the correct sequence of bits. Framing is off in my test printfs but that's neither here nor there).	2016-07-31 13:32:30 -04:00
Thomas Harte	8f62211f5e	Wired up the 1540 as a PLL delegate. Which prima facie means it should start receiving a bit stream. Except that I clearly have something in the timing way off — either my flux transitions are far too short or I need to significantly increase the clock rate on the PLL.	2016-07-29 12:08:18 -04:00
Thomas Harte	89a1881fef	Started turning the 1540 into an actual disk drive.	2016-07-29 11:03:09 -04:00
Thomas Harte	ada2f073e0	Completed handing of the disk all the way to the 1540.	2016-07-10 16:24:46 -04:00
Thomas Harte	824d9ea92b	Added further comments.	2016-07-10 08:01:16 -04:00
Thomas Harte	d8334edf4a	Started trying to clean up, including commuting the C1540 source file name to match its class name but mainly by adding documentation.	2016-07-10 07:46:20 -04:00
