Reintroduces a warm-up run for the C1540.
...
That simulates the normal real-life scenario of switching the drive on slightly before the computer, and causes it to function correctly from immediate fast typing on an American Vic.
Also switches a couple of casts within the C1540 to functional style.

Modifies the Vic-20 and C1540 to bring them into the realm of self-ROM fetching.
...
Hence enables Vic-20 support within kiosk mode as currently drafted.

The Amstrad volunteers itself to be single sided. Everything else stays as it was.

Updates the 1540 for the slightly-more modern world of decoupled drives and disks (!).

96bf133924
Withdraws requirement for DiskController users to specify a PLL multiplier or to provide rotation speed.
...
In the latter case because it's no longer of any interest to the controller, and in the former because I'd rather it be picked automatically.

Corrects non-recurring-pattern adaptation bug: the 'SerialPortVIA' should keep a reference to its VIA, not a copy of it.

Thomas Harte
6547102511
Attempts better to hide C1540 implementation details from the reader.
...
In this case not from the compiler, as it's desireable to keep `run_for` as a non-virtual call, and therefore everything else comes alone for the ride.

Deconstitutes the 6522 into component parts, templated and non-templated.

Adjusts the Oric, Vic-20 and C-1540 accordingly, albeit with the quickest possible solutions.

ee71be0e7e
Added the option not to include ready line support in the 6502 core, and took advantage of it in the Electron, Oric and Vic-20 implementations. Also tagged those as forceinline and/or override final where applicable.
2017-08-21 21:56:42 -04:00
Thomas Harte
42b5b66305
Remove the 6502's use of runtime polymorphism in favour of ordinary templating.

4abd62e62b
Standardises on const [Half]Cycles as the thing called and returned, rather than const [Half]Cycles & as it's explicitly defined to be only one int in size, so using a reference is overly weighty.
2017-07-27 22:05:29 -04:00
Thomas Harte
279c369a1f
Switched to Cycles as the result from the 6502 perform_bus_operation, helping slightly to clarify what you're intended to return and reducing type jumping within the 6502 implementation.

Experimentally turned the 6502 into a clock receiver. No problem encountered.

Switched to use of std::vector in those few remaining places where I was still using a unique_ptr to a native type and newing for myself. So, some of my earliest bits of code.
2017-07-16 13:54:07 -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.

Made a first stab at enabling multi-disk machines and thereby obeying (some of) the Plus 3's status register.

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.

Gave disks their own namespace.

Reduced 1540 PLL to running at 4Mhz. Which is possibly correct (?) Made minor change to avoid divide if possible.

It appears the problem is as simple as sectors being counted from zero.

Some minor tidying, lots more of the caveman stuff as I try to determine what I'm doing wrong.

Slightly updated comments, switched to 1540 ROM so as very slightly to improve loading time.

Fixed framing and first-byte-after-sync signalling. Hacked together as parts of it are, loading now appears to work!

Put in the absolute minimum logic for drive motor emulation. Drive appears to be attempting head steps.

Added overflow-flag setting logic and ensured disk ROM gets through regardless of ROM/disk installation order.

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).
2016-07-31 13:32:30 -04:00

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.
