* Renamed to MCS-40.
* Emulated 8-clock instruction cycle, interruptible at any point.
* Converted TEST input to an input line.
* Added SYNC and CM output lines.
* Added support for 4040 CY output, logical operations, extended registers, ROM banking and disassembly.
* Made I/O space mapping more flexible to support the variety of peripherals available.
* Notable missing features are 4040 interrupt and halt, and "program memory" space.

Spirit of 76 [PinMAME]
New not working clone
-----------------------------------
Black Knight 2000 (PF-1) [PinMAME]
* Tromba (trumpet) sound is not working - requires Schmitt trigger device
* Connecting cassa (bass drum) swamps other instruments so it's disconnected for now
* Mixing melody sound with speech/SFX is not done in netlist (should be)
* Relative levels of melody/speech/SFX are probably still wrong
(nw) A good test case for this is the Money Money driver (monymony).
There's a bit of buzzing on this one as well. The problem with the
cassa could be caused by running into non-ideal characteristics of opams
again (the LM3900 seems to ignore the V+ value supplied to it). When
the netlist library gets Schmitt trigger support, the tromba can be
completed. Unfortunately, the tromba is a key part of the
characteristic sound of these boards, so you really notice when it's
lacking.
(nw) It doesn't work quite right yet. The "Hammer" and "Pest" sounds
are generated by free-running 555/556 timers and gated with LM324
applifiers. For whatever reason, the netlist system produces a kind of
buzzing from the "Hammer" circuit when it's supposed to be suppressed,
and it doesn't think the pest sound should be suppressed completely so
you can always hear it at a low level in the background. The "Cheese"
circuit is a bit weird - either they're using the base-emitter junction
of a 2SC945 as a signal diode, or there's an error in the schematic
(collector is shown unconnected). Connecting this part of the circuit
causes the netlist system to hang, so R2/R3/C8/Q2 are not connected for
now.
The core changes are:
* Short name, full name and source file are no longer members of device_t, they are part of the device type
* MACHINE_COFIG_START no longer needs a driver class
* MACHINE_CONFIG_DERIVED_CLASS is no longer necessary
* Specify the state class you want in the GAME/COMP/CONS line
* The compiler will work out the base class where the driver init member is declared
* There is one static device type object per driver rather than one per machine configuration
Use DECLARE_DEVICE_TYPE or DECLARE_DEVICE_TYPE_NS to declare device type.
* DECLARE_DEVICE_TYPE forward-declares teh device type and class, and declares extern object finders.
* DECLARE_DEVICE_TYPE_NS is for devices classes in namespaces - it doesn't forward-declare the device type.
Use DEFINE_DEVICE_TYPE or DEFINE_DEVICE_TYPE_NS to define device types.
* These macros declare storage for the static data, and instantiate the device type and device finder templates.
The rest of the changes are mostly just moving stuff out of headers that shouldn't be there, renaming stuff for consistency, and scoping stuff down where appropriate.
Things I've actually messed with substantially:
* More descriptive names for a lot of devices
* Untangled the fantasy sound from the driver state, which necessitates breaking up sound/flip writes
* Changed DECO BSMT2000 ready callback into a device delegate
* Untangled Microprose 3D noise from driver state
* Used object finders for CoCo multipak, KC85 D002, and Irem sound subdevices
* Started to get TI-99 stuff out of the TI-990 directory and arrange bus devices properly
* Started to break out common parts of Samsung ARM SoC devices
* Turned some of FM, SID, SCSP DSP, EPIC12 and Voodoo cores into something resmbling C++
* Tried to make Z180 table allocation/setup a bit safer
* Converted generic keyboard/terminal to not use WRITE8 - space/offset aren't relevant
* Dynamically allocate generic terminal buffer so derived devices (e.g. teleprinter) can specify size
* Imporved encapsulation of Z80DART channels
* Refactored the SPC7110 bit table generator loop to make it more readable
* Added wrappers for SNES PPU operations so members can be made protected
* Factored out some boilerplate for YM chips with PSG
* toaplan2 gfx
* stic/intv resolution
* Video System video
* Out Run/Y-board sprite alignment
* GIC video hookup
* Amstrad CPC ROM box members
* IQ151 ROM cart region
* MSX cart IRQ callback resolution time
* SMS passthrough control devices starting subslots
I've smoke-tested several drivers, but I've probably missed something. Things I've missed will likely blow up spectacularly with failure to bind errors and the like. Let me know if there's more subtle breakage (could have happened in FM or Voodoo).
And can everyone please, please try to keep stuff clean. In particular, please stop polluting the global namespace. Keep things out of headers that don't need to be there, and use things that can be scoped down rather than macros.
It feels like an uphill battle trying to get this stuff under control while more of it's added.
