45b169f341 Made a few mapping fixes, clarified where the default reset code lives, ensured the Oric and Vic clear their keys when the typer ends. 2016-11-05 15:28:03 -04:00
Thomas Harte
338904fffe Made similar cleanings of the Electron and Vic. 2016-11-05 15:07:57 -04:00
Thomas Harte
9fb9d92437 Made the typer much more able to help out, and thereby tidied and separated the Oric's typer. 2016-11-05 14:47:09 -04:00
Thomas Harte
4fab794747 Added a direct-to-two-cycles emulation path for 6522 owners. 2016-10-27 21:13:25 -04:00
Thomas Harte
c5948ef177 Evicted more header-resident code. 2016-10-20 21:05:32 -04:00
Thomas Harte
6d7c3f6ac2 Factored out the now-sampling binary-level tape player from the Vic and connected it up to the Oric. 2016-10-15 21:21:18 -04:00
Thomas Harte
cd1ab09701 The Vic-20 now inserts ROMs again. 2016-09-29 20:15:25 -04:00

142254a478 Resolved failure to open disks that arrive through analysis. 2016-09-17 18:11:58 -04:00
Thomas Harte
e3571e8b9e Added insurance against an infinite loop should the tape be exhausted. 2016-09-12 22:22:23 -04:00
Thomas Harte
40660fe680 Made yet another guess at Commodore analysis. Elevated fast tape-related unnatural speed up to the OS-side mechanisms. 2016-09-12 22:06:03 -04:00
Thomas Harte
e54a2326a3 Made attempt to run at zero cost while processing tape input. 2016-09-11 17:34:02 -04:00
Thomas Harte
eeec516fa6 Implemented seeking on tapes, mucked about a bit more with the Commodore analyser, at least temporarily removed cropping from the Vic emulator. 2016-09-11 17:09:00 -04:00
Thomas Harte
50175a9aed Added logic to try to spot when the first program is BASIC and, if so, what the correct memory model is, then to get that information to the Vic. Though it currently then gets overwritten by the view controller. Grrrr. 2016-09-07 22:17:19 -04:00
Thomas Harte
56c0d70c1f Gave disks their own namespace. 2016-08-27 17:15:09 -04:00
Thomas Harte
c0402d0c2b Gave tapes their own namespace. 2016-08-27 17:09:45 -04:00
Thomas Harte
55ada536ac Added a test call, further mutated result structure. 2016-08-27 14:25:16 -04:00
Thomas Harte
dab3580111 Experimental: can I afford a lower sampling rate if there's a low-pass filter in effect? 2016-08-22 22:18:05 -04:00
Thomas Harte
1541273785 Moved responsibility for throwing in a low-pass filter up to the Vic, appropriately. 2016-08-21 18:13:31 -04:00
Thomas Harte
99157ad6b2 Ensured the 6560 knows its real audio clock on a PAL machine; removed some stray semicolons. 2016-08-19 13:35:34 -04:00
Thomas Harte
e985c72ce8 Removed a dead special case. 2016-08-19 12:23:06 -04:00

4edd1214f1 This has now successfully loaded its first PRG-as-a-tape. 2016-08-19 10:58:42 -04:00
Thomas Harte
2935848f35 Adopted header/header/data/data pattern. But still not complete joy. 2016-08-17 08:03:34 -04:00
Thomas Harte
dfe9fb83ef This proves that bytes are being deposited properly. For the first 36 anyway, and with no announcement. 2016-08-16 21:09:50 -04:00
Thomas Harte
12f8aff65b Lengths I'd taken seem to have been for dipoles, not single poles. So I just doubled the clock rate. Also I was producing each dipole as high then low, when they should probably be low then high. The Vic now at least recognises that something is happening on the tape. 2016-08-16 19:46:53 -04:00
Thomas Harte
ca2dc6b6c4 Ensured ROMs survive in the new memory model. 2016-08-15 19:56:01 -04:00
Thomas Harte
38aec44d85 Made sufficient changes for the Vic itself to believe it can recast a PRG as a tape and insert it that way. So now the ball is in the court of: how the heck are Commodore tapes encoded? 2016-08-15 19:44:41 -04:00
Thomas Harte
547aefb696 Slightly adjusted PRG strategy, made a note about where next. 2016-08-14 16:36:42 -04:00
Thomas Harte
d9016909ed Added some wiring for PAL/NTSC mode switching on the Vic, making an attempt to simplify the whole loop of having different clock rates. 2016-08-14 13:33:20 -04:00
Thomas Harte
a547b7e1d8 Took basic steps towards supporting memory expansions. 2016-08-13 17:21:25 -04:00
Thomas Harte
12bad8f23f Turned the 6560 into an ordinary template, similar to the rest of the project, albeit right now with a fairly shonky internal implementation. Fixed a Mac-specific interface sizing issue. 2016-08-09 20:41:05 -04:00
Thomas Harte
be54d8040e Made a first stab at having automatic loading be optional. But things are currently arranged such that the machine options are communicated too late to have an effect. So work to do. 2016-08-06 17:39:27 -04:00
Thomas Harte
3e65450a54 Converted the 6560 fully into a template; worked on allowing the typer to run at a much faster rate where hardware has some trigger by which it can request the next key. 2016-08-06 14:33:24 -04:00
Thomas Harte
5d40d70c92 Fixed 6560 addressing error, added an autotyper for Vic disks (more work potentially needed), fixed semantics for testing whether a 6502 is about to reset. 2016-08-01 10:32:32 -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
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
ada2f073e0 Completed handing of the disk all the way to the 1540. 2016-07-10 16:24:46 -04:00
Thomas Harte
6cfc514c2d Made the rote changes necessary to attempt to open and to supply a G64 to the Vic. 2016-07-10 12:57:17 -04:00
Thomas Harte
4ca6883f7c Disabled attachment of a 1540 again, as I probably need to move to opening an actual disk image next. 2016-07-10 08:03:36 -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
Thomas Harte
c0ab45a73d Disabled a bunch of the caveman debug logging. 2016-07-09 22:29:11 -04:00
Thomas Harte
f589d639db Okay, so it seems that sync also works the other way around. 2016-07-09 22:25:44 -04:00
Thomas Harte
693c8b2438 After all that, it seems likely that inputs just aren't inverted for the Vic. 2016-07-09 20:03:38 -04:00
Thomas Harte
1baf21827c Since the ROM is well disassembled, let's actually try to be a 1541 first. 2016-07-06 22:17:32 -04:00
Thomas Harte
f64cd8cfcb Quick fixes properly to declare the DriveVIA, to ensure its interrupts take effect, and to wire ATN IN to CA1 rather than CB2. 2016-07-06 20:22:46 -04:00
Thomas Harte
d16b79073e Further fleshing out: added a serial port for the serial bus. 2016-07-05 17:27:02 -04:00
Thomas Harte
d1eea6943d Ensured the 1540 ROM gets installed, at least. 2016-07-05 16:54:25 -04:00
Thomas Harte
86dabd007b Furthered fleshing out of the 1540. Though it doesn't yet receive a ROM so won't even attempt to do anything meaningful. 2016-07-05 16:39:18 -04:00
Thomas Harte
a25fcc7190 Made a first attempt at wiring back serial port input. 2016-07-05 16:10:54 -04:00
Thomas Harte
d2cded7b59 Attempted to separate out the concept of a serial port and a serial bus, since the bus may be shared, and to establish half duplex communications from the Vic. 2016-07-05 14:55:20 -04:00
Thomas Harte
0d3d0fbe4d Created a namespace for Commodore and an empty container file for the 1540[/1] implementation. 2016-07-05 13:28:27 -04:00
