 2021-06-03 22:22:56 -04:00
Thomas Harte
a30eeaab6a Starts to introduce a new grammar for ROM requests.

d77ddaf4fa Switches the Electron to JustInTimeActor video. 
Also reorders template parameters; I think that specifying a different time base is likely to be more common than using a divider.

Thomas Harte
67408521cd Makes absolutely sure not to try to use quickboot workaround for Mac 128kb/512kb. 
Albeit that it should be harmless; it's just seeding RAM.
 2021-03-06 22:34:35 -05:00

9781460c41 Thanks to a hint from the MAME guys: finally completes Macintosh 128kb and 512kb emulation (!) 2021-02-26 21:22:35 -05:00

Thomas Harte
3d91b0a31b Fixes keyboard data return.

 2021-02-19 21:55:06 -05:00
Thomas Harte

Thomas Harte
72d7901c88 Takes a shot at the keyboard data full flag. 
Just a guess. But likely?
 2021-02-19 20:06:12 -05:00
Thomas Harte

fa8236741d Takes a shot at an ADB mouse. 2021-02-15 20:49:16 -05:00

Thomas Harte
eccf5ca043 Makes first effort to wire up the ADB vertical blank input. 
However: looking at the disassembly, I'm not sure it really is wired to INTR. So work to do.
 2021-02-14 22:20:58 -05:00
Thomas Harte
24af62a3e5 Sets a default handler of 1. 2021-02-14 22:20:07 -05:00

Thomas Harte
6e53b4c507 Corrects centralised ADB decoder. 
I still think it's appropriate to do this in only a single place, given that using it is optional.
 2021-02-14 20:41:05 -05:00
Thomas Harte
52c38e72f6 Starts seeking to automate register 3 handling. 
Immediate pitfall: byte capture on the bus side isn't working correctly.
 2021-02-14 20:37:33 -05:00
Thomas Harte
a51d143c35 Corrects reactive-device transmission logic. 
Albeit that I'm still not properly responding to register 3 stuff, so the ADB bus needn't believe anything is out there. Also, without VSYNC being piped to the microcontroller it may well just not be polling anyway.
 2021-02-14 18:54:22 -05:00
Thomas Harte
17e9305282 Starts adding a keyboard. 2021-02-13 23:16:45 -05:00

Thomas Harte
33abdc95aa Adds a helper for decoding ADB commands. 
Still very noticeably to do: any sort of standard part for devices to respond to the bus.
 2021-02-10 21:39:33 -05:00
Thomas Harte

Thomas Harte
46bd20b5e0 Attempts to simplify ADB bit parsing. 
On-line output still looks reasonable, albeit that the microcontroller suddenly seems to be interested in devices F and 3 rather than 2 and 3.
 2021-02-08 22:08:49 -05:00
Thomas Harte

 2021-01-30 17:53:27 -05:00
Thomas Harte
f50e8b5106 If I'm going to maintain the max_address approach, & is 'correct'. 
% +1 would be 'more correct', but I think this approach is probably misguided.

Thomas Harte
e8e604dc3c Attempts to wire up M50470 and GLU.

 2021-01-24 18:07:05 -05:00
Thomas Harte
57e0fdfadc Ensures ADB microcontroller is clocked. 
And runs at the 'correct' speed (i.e. modulo my instruction-by-instruction implementation).
 2021-01-23 22:55:12 -05:00
Thomas Harte
ec0018df79 Routes in the ADB keyboard ROM. This should get as far as parsing. 2021-01-18 16:59:49 -05:00
Thomas Harte

Thomas Harte
65ca931e83 Throws in a new assert, against the unimplemented bit 0 of new video. 2020-12-06 20:26:24 -05:00
Thomas Harte
6cb71eb11b This needs explicitly to be a bool for the table lookups to work. 2020-12-06 16:43:07 -05:00
Thomas Harte
43251193ee The actual maximum line length is now 656. 2020-12-06 16:42:43 -05:00
Thomas Harte
55de98fb46 Adds a new statement of intent. 
Now I need to try to decide whether I like my current all-in-one mapping for shadowing + paging, or whether it's better to split the things. I'm tending towards the latter at least until the functionality works.
 2020-12-05 19:09:21 -05:00

Thomas Harte
187f507532 The soft switch is LCBANK2, not LCBANK1. 
[This also jimmys the IIgs into always entering its extended self test, for now]
 2020-11-30 22:35:51 -05:00

Thomas Harte
11fe8ab6db Corrects counter scales, adds a read for $c032. 
Albeit that I have no idea what that's supposed to read as.
