Thomas Harte	81ee834530	As well as a bunch of logging, reinstated rotation position preservation across tracks.	2016-12-02 18:36:47 -05:00
Thomas Harte	93c573bfa9	Implemented missing status bits (other than the index hole), and a head loading delay for the Microdisc.	2016-12-01 21:13:16 -05:00
Thomas Harte	442986ee2c	Introduced a head loading path for 1793 machines.	2016-12-01 20:12:22 -05:00
Thomas Harte	82899f2f47	Ensured flag setting is atomic, removed duplication of interrupt request versus busy, found better names for the personality testers, unified delegate protocol.	2016-12-01 07:41:52 -05:00
Thomas Harte	9b6c5e814a	Now that it can be more explicit, this should admit that it's '93-based, not '73.	2016-11-28 16:22:35 -05:00
Thomas Harte	2f459690d4	It would appear the 1770 and 1773 actually differ in relation to the (non-sensical) ability not to spin-up for a Type 2, and whether a side compare can occur. So the WD1770 class now requires a personality to be specified. Which it singly fails to honour.	2016-11-26 23:29:30 +08:00
Thomas Harte	e9d6566e9c	Of course, changing the IRQ enable may immediately change the IRQ line. Signal if so.	2016-11-26 09:35:44 +08:00
Thomas Harte	54246c8f1a	Interrupt enabling works the other way around I think, and both registers with only one bit defined should probably return '1' in all other places?	2016-11-25 21:24:59 +08:00
Thomas Harte	5c019ad1c0	Okay, so it looks like both ROM paging flags are the opposite of what I previously had.	2016-11-25 20:42:40 +08:00
Thomas Harte	7c2d9f3752	This seems to be right, per http://wiki.defence-force.org/doku.php?id=oric:hardware:floppy_disk_controller_wd1793	2016-11-22 22:35:43 +08:00
Thomas Harte	0c3644f350	Made a second parse at logic. We'll see.	2016-11-22 22:12:32 +08:00
Thomas Harte	13a608a8c2	Added what may be correct paging logic.	2016-11-22 22:09:52 +08:00
Thomas Harte	363db695e8	Started implementation of the Microdisc selection logic.	2016-11-22 08:12:53 +08:00
