eb8a2de5d6 Settled definitively on flush as more communicative than synchronise (and slightly more locale neutral); culled some more duplication from the Z80. 2017-05-15 07:38:59 -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
8e35e913bb Formally withdrew the 'load automatically' option for the Vic, having removed that option elsewhere. 2017-05-14 16:59:24 -04:00
Thomas Harte
2edf73908c Temporarily disabled the existing fast loading implementation in pursuit of another, and started trying to correct the lack of connection between the userport VIA and the tape drive. 2017-05-06 22:00:12 -04:00
Thomas Harte
e01f3f06c8 Completed curly bracket movement. 2017-03-26 14:34:47 -04:00

1b1a8d3e52 Brought the Vic-20 into suffix naming. 2016-12-03 13:30:27 -05:00
Thomas Harte
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
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
142254a478 Resolved failure to open disks that arrive through analysis. 2016-09-17 18:11:58 -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
8c84f3581a Attempted to bring some uniformity in application of configurations. 2016-09-08 05:32:17 -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
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
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
142774be37 Collapsed 6560 template to a more direct loop, albeit with quite a bit still left to fix. 2016-08-09 21:10:53 -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
285a288c80 Switched to two cycles of options loading, meaning that they get set before files are inserted. Might need some further work? 2016-08-07 21:48:09 -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
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
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
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
81e6cc34e5 Per the ROM disassembly, the Vic's VIA outputs are inverted for the benefit of the serial bus. 2016-07-07 06:57:21 -04:00
Thomas Harte
c9479f923b The inversion of truth was clearly just a problematic API. Got explicit. LineLevel might need to become more pervasive. 2016-07-07 06:44:13 -04:00
Thomas Harte
dcb86a027a Okay, so the 1540 doesn't toggle the actual attention line. I don't know what it does yet but this helps. 2016-07-06 22:31:14 -04:00
Thomas Harte
428fcdb978 Centralised and improved serial logging. 2016-07-06 07:46:21 -04:00
Thomas Harte
11fc43aa04 Made an attempt to allow the 1540 to talk back to the Vic, and to receive interrupts. Also slightly disambiguated debugging logging. 2016-07-05 19:12:43 -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
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
