063a62372f The Commodore serial bus and C1540 are now postfix underscorers. 2016-12-03 13:14:03 -05:00

4fab794747 Added a direct-to-two-cycles emulation path for 6522 owners. 2016-10-27 21:13:25 -04:00

6292ac5b26 Yet more .hpp clean(s)ing. 2016-10-20 21:15:21 -04:00

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

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

56c0d70c1f Gave disks their own namespace. 2016-08-27 17:15:09 -04:00

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

bc10b3ee9a It appears the problem is as simple as sectors being counted from zero. 2016-08-01 10:08:38 -04:00

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

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

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

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

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

198fbbedc7 Reeled back all appropriate pieces of caveman debugging. 2016-07-31 13:42:34 -04:00

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).

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

89a1881fef Started turning the 1540 into an actual disk drive. 2016-07-29 11:03:09 -04:00

ada2f073e0 Completed handing of the disk all the way to the 1540. 2016-07-10 16:24:46 -04:00

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
