* should be #included after other headers and after optionally #defining VERBOSE
* usage samples in z80scc.cpp and m68705.cpp
68705: add lots of logging to help trace issues
m68705: expose more more internal registers through the state interface
* shows contents of registers that can't be read by program code
i8251: make receive more reliable clean up a little
zorba: meat on the bones
* create emulated keyboard device
- 88 of 96 matrix keys identified, 6 of 8 DIP switches identified, 3 of 6 outputs identified
* connect IEEE-488, RS232 and Centronics ports
* hook up all IRQ sources and connect PIT to UARTs
* more notes
osborne1, gladiatr: use input changed member (nw)
- refactored reverse polish notation evaluator into own source files.
- added function parameter to current and voltage sources VS and CS.
You can now use those to e.g. produce a sine wave.
- Changed code to allow devices to optionally be treated as dynamic or
timestepping devices.

* remove non-obvious mcu_status_r and semaphore_r members and move to drivers (varies by system)
* slap fight functionality can be safely folded into base class so do so
* remove leftover crud from driver state classes
qix.cpp, bub68705, changela: use new MC68705P3 core
* Moved 68705 devices into their own file.
* Made P3, P5 and U3 variants and made them load bootstrap ROMs.
* Implemented EPROM control (write is stubbed out with a logerror).
* Implemented differences for open drain I/O ports.
(nw) Base device with peripherals should really derive from the 6805
device directly, not the 68705 devices, as I/O ports are present on mask
devices (e.g. 6805P2). All drivers and devices that were using
M68705_NEW have been changed to M68705P5 - someone who knows the drivers
better should fix them up.
- Conversion of the Cedar Magnet board from a base device class to a mix-in interface
- Emulate EFO ZSU as main variant of the Cedar Magnet sound board
- Hook up ZSU1 to Skill Flight and Phantom Ship
- Modernize ZSU soundlatch/IRQ mechanism
- More hardware notes (nw)
- Various associated code cleanups (nw)
into these files as well. The code uses <cfenv> which is part of c++11
standard. Non-standard glib extensions are currently only used on linux
and (i386 or x86_64). (nw)
we've been sitting on this for a while, progress was shown a few years ago, but is apparently lost. Smitdogg should be able to clarify the exact part numbers, they're not readable in the pictures.
Mario driver now uses netlist audio implementation instead of discrete
implementation. The previous discrete sound emulation has not been
removed yet because it still contains a lot of documentation.

in the mizar lib. This is suboptimal, but the code seems to
crossreference across object files and from the bus code into the driver
code.
At least the source now links again. (nw)
- MSM5205 hooked up through 40105 FIFO
- Various notes based on Z80 code and schematics for related pinball sound board
40105 device improvements (nw)
- Split up configuration macros
- Tweaked device name and device type name
- New callback for automatic output write
- A few bug fixes for so_w
- Many comments and pinout added
- Allow stringing multiple callbacks together recursively. Chained callbacks will be read or written in sequence, and each can be configured with its own type and mask/shift/XOR parameters.
- Chained input callbacks cannot have overlapping masks (there's no such thing as a free multiplex). Chained output callbacks have no such restriction.
- Remove the constant parameter for the LOGGER callback type: it makes no sense for output, was always zero in existing usage, and is now unnecessary with callback chaining.
- Change LOGGER behavior for writes to log the user-defined message only if the output as masked is nonzero. With callback chaining, this can be used to monitor when individual bits become active.
- Constant read callbacks can no longer have MCFG_DEVCB_XOR or MCFG_DEVCB_INVERT specified (makes no sense in this context).
- Add a MEMBANK callback type to allow output bits to be used for bank-switching.
- Add ASSERTLINE and CLEARLINE callback types that raise or lower an interrupt line if the selected bit of the written value is active. These are intended for where periodic or ready-pulse signals from devices are used to trigger IRQs that the CPU program will independently acknowledge.
- Add MCFG_DEVCB_BIT as shorthand for masking and shifting out an individual bit for a callback.
- Removed DEVCB_LINE_DISPATCH_<n>. Where we're going, we don't need line dispatcher devices.
The incompatibility of compilers with regard to post-C90 printf string formats is shockingly bad. There seems to be no easy way to format a 64-bit value and please both gcc and clang, let alone MSVC.
-netlist: Added new devices: [Ryan Holtz]
* Intel 2102A 1Kbit (1024 x 1) Static RAM
* 74365 Hex Bus Driver with 3-State Outputs
* Generic 2- and 3-terminal Tristate device
* Note: Tristate device and 74365 do not actually tristate, they are simply a way of combining multiple outputs + chip enables.
