-nscsi_cd.cpp: Added various new-SCSI CD-ROM devices which support 512-byte blocks by default. [Ryan Holtz]
-sgikbd.cpp: Added a rudimentary HLE SGI Indigo keyboard device. Still needs keys to be mapped. [Ryan Holtz]
-indigo.cpp: Various changes: [Ryan Holtz]
* Expanded logging.
* Enabled PIT8254 timer. Has the wrong clock value; the correct clock causes a hang.
* Improved RAM layout.
* Added stubs for DSP RAM and Entry-level graphics.
Two sample roms are missing, sad. Volume is not taken into account
yet (because the registers are not yet understood), pan is though.
Don't even think about reverb or effects :-)
Current code plays a scale in a loop. Comment the timer alloc in
machine_reset to kill that.
Demo song (missing lots of sounds, because roms): U then > until demo
then ENTER ENTER.
-change order of include files at top of i386.cpp
-move some routines between i386.cpp and i386priv.h
-move part of x87ops.hxx into new file x87priv.h
.
Now you only have to rename the hxx files to cpp and add the following
at the top of each one
.
#include "emu.h"
#include "i386.h"
#include "i386priv.h"
#include "x87priv.h"
#include "cycles.h"

Connected SMIOC DMA to 68k
* SMIOC now reading bytes for serial from the 68k memory space successfully.
commit 0f801a05a3fa5b78768a1a2bcb9981466e8f2b0e
Author: Stephen Stair <sgstair@akkit.org>
Date: Tue Mar 27 18:31:32 2018 -0700
68k now running in lockstep with SMIOC for serial
* 68k now uses actual SMIOC as source of SMIOC status, so it waits for the SMIOC to complete commands before continuing.
* SMIOC DMA controllers now being asked to move bytes around
* "write character" (4100) commands to SMIOC are now completing and resulting in correct status being written and sent back to the 68k
* Every now and then the SMIOC stalls for a bit, it seems to be due to spending some time trying to communicate with the 8051 CPU (used to communicate with another cpu on the serial breakout box) that is not currently present in the emulated device.
Next Steps:
* We're going to move the terminal from the r9751 into the SMIOC, and hook it up to the DMA controllers as a hacky temporary solution.
* We need to emulate the 5xxxx memory range in SMIOC to proxy data to/from the 68k memory
* Then we'll start work on emulating the octal uart properly and hooking it up to RS232 channels.

Tinkering to get SMIOC further along
1) Enable 188 cpu to advance DMA immediatley if DRQ is held high when source synchronous DMA is started (It's not clear whether the DMA actually works this way yet)
2) Retrigger the DMA DRQ when a memory access is made to the DMA window (future work needed to proxy the reads/writes to the 68k's main memory) This is needed to support multibyte DMA reads/writes to the 68k window.
3) Reverse the bytes in the status register (based on current incomplete understanding of how this is encoded)
4) Connect the status register back to the r9751 on SMIOC status read
Current state: SMIOC's main board DMA state machine now completes the DMA transfer from the main board (With incorrect data), but we are still getting stuck.
Next steps: SMIOC is now hanging waiting on DMA to UART to complete, we need to implement some emulation of the UART and its connections to the surrounding 16 dma channels in order to make progress.

Experimenting with SMIOC emulation
* Partial fixes for line state issues with persistent line values
When the AM9517 DMA controller mode is updated to change the polarity of DACK/DREQ, it doesn't update the DACK line values / request values (respectively).
This fixes this issue for one of the emulated devices in the file, but the other device has the same problem.
* Add skeleton of SCC2698B UART device
* Early progress on emulating SCC2698B Octal UART
Core structure for IO lines and writing registers is in place.
* Update address maps to new format.
* SCC2698b: Add tx/rx, baud rate generation
* Emulation improvements for scc2698b device
* MPP output pins emulated
* Improved logging for baud rate changes
* Channel configuration emulated
* Support for TX/RX Enable
* Started integrating new features into SMIOC
* Minor progress on the path to enabling new UART for SMIOC
* Resolved code issues related to upstream changes
* Working around an apparent problem with callbacks on sub-device devices
* Terminal added for serial port attached to SCC2698B UART.
* Things compile and seem to work.
* SMIOC: Serial is now outputting correctly through emulated SMIOC
Some glitches to work out, but this is nearly ready.
* AM9517a should not forget about input line status on master reset.
* Disable tracing
* SMIOC: Improving diagnostics and making some progress on the emulation
* Revised tracing in SMIOC and SCC2698B
* Improved tracing approach in r9751
* Minor progress towards working SMIOC emulation.
* [R9751] Update drivers to new code patterns after rebase
Rebased on latest mame, Fixed a few issues and updated the callback code patterns based on recent changes in devcb
* [R9751] Improve logging, fix interrupt race
Serial no longer drops output characters
* [R9751] Working on SMIOC emulation
Improved SMIOC emulation accuracy, Made some progress in getting through the disktool initialization sequence, but we are still hitting a problem - It looks like disktool should be resetting the SMIOC board when it starts, but the mechanism for this has not been found.
* [R9751] Improve tracing for system board registers
* [R9751] Improve SMIOC emulation
Still having some trouble with SMIOC but this seems to be an improvement.
SMIOC is now waiting for a status to be read before applying a new status, and mandatory parameter read logic is in place.
* [R9751] Incremental emulation improvements
the SMIOC failure was understood and fixed, and a new approach to getting the hardware to bootstrap correctly was implemented - Still having some problems with it though.
* [R9751] Fixed emulation issues
* Disktool now boots to the console
* UART receive only partly working, I don't think it's fully connected yet.
* [R9751] Further progress on SMIOC emulation
* Figured out the missing command parameter interface to the SMIOC board
* Still blocked because the SMIOC interface to the breakout board through an onboard 8051 is not emulated and the disktool software depends on properties coming from it.
* [R9751] Terminal is fully working for disktool
* Improved the emulation of the 80188 to 451 connection in order to reliably set a status bit disktool depends on.
* [R9751] Fix build after rebase
* [R9751] Cleanup, tracing improvements
* Remove second emulated terminal - SMIOC is now stable enough to run the terminal.
* Remove older and unnecessary emulation/tracing code
* r9751: Fix compile error and modify copyright holders
Zilog Z8038 FIO (FIFO Input/Output Interface Unit). Used to drive the parallel/printer port on the MIPS Rx2030. Passes basic diagnostic tests, but further work depends on progress in the mips.cpp driver.
On HP9000/300, these modules where always a logical unit connected to
the DIO bus. On some systems this was even a seperate DIO module. Lets
represent this in software. It also cleans up hp9k_3xx.cpp.
A skeleton for the Microsoft Jazz architecture, which was implemented in the MIPS Magnum 4000, Olivetti M700-10 and was the base/origin of several other MIPS ARC systems.
* added skeleton Inmos G300/G332/G364 device
* added skeleton NatSemi DP83932C SONIC device
* added skeleton MCT-ADR device
* Separate Microsoft 2-button mouse and Logitech 3-button Microsoft-compatible mouse
* Add Microsoft wheel mouse
* Make Mouse Systems mouse behave more realistically
* Add Mouse Systems "rotatable" mouse
* Simplify code and eliminate timers
(nw) X/Y translation and buttons works for all devices. The wheel on
the wheel mouse seems to be transmitting the right data, and CuteMouse
detects the wheel as being present, but no software seems to support it
properly. Software supporting the Mouse Systems "rotatable" mouse is
very rare - typically people just set the DIP switches on their M-1 for
"non-rotatable" mode. A standard mouse driver will see the "rotatable"
mouse moving two mickeys for each count, and move eratically on
rotation. The "rotable" mouse is poorly tested due to lack of software.
(nw) MAME doesn't have a proper input type for a mouse wheel, and it
doesn't seem to be possible to map the host mouse wheel to an axis when
configuring inputs. The default mapping ends up assigining the wheel or
rotation to one of the translation axes, which is very unhelpful.
Also add notes to Sun keyboard emulation.
There's a hack to make the 1200 Baud mouse actually run at 9600 Baud.
This is necessary because the SCC is incorrectly expecting 9600 Baud
rather than 1200 Baud. I don't have time to fix the SCC, so I'd
appreciate it if someone else would.
There's no way it should be expecting 9600 Baud on the mouse port.
Solaris 2.3 and later support 1200 Baud and 4800 Baud, and earlier
versions support 1200 Baud only. No version of Solaris works with a
9600 Baud mouse.
The workaround allows the mouse to be used in SunView on sun4_60 - I
haven't tested any other drivers.
* Add huc6230 Emulation

* Implement Mitsumi Amiga 500, 600, and 2000/3000/4000/CDTV keyboards
* Add unlabeled keys to UK layout
* Restrict available keyboards depending on system type
* Note that C-A-A reset is now broken on "big box" Amigas as MAME doesn't implement it properly, and the hack providing a fake dedicated reset line has been removed
6502 MCU: fix execute loop
6500/1: implement as device with onboard peripherals
Fix some bogus comments
(nw) New keyboard only has U.S./Canada and UK variants for now. This keyboard doesn't
drive a dedicated reset line, instead using some sequence on the clock line detected by
the host chipset. MAME doesn't support this, so keyboard reset won't work. Also started
documenting the character labels on the keypad NumLock/ScrLock keys for language variants
but still need more pictures.
* taptun: add support for Windows
Looking for feedback only at this point, because it's the first time I've attempted any OSD stuff - be gentle.
This extends the existing taptun OSD module to support Windows through the TAP-Windows6 driver (https://github.com/OpenVPN/tap-windows6).
* TAP-Windows6 is GPLv2, however only the header file is required in MAME, and the driver itself is entirely optional.
* I've tried to minimise the size of the diff, rather than completely separate the Windows/non-Windows implementations - not sure which is preferable in this case.
* The license file has Mac(?) line-endings - unsure if they should be normalized or used verbatim.
* Uncertain about the non-Windows case (or the Windows SDL case) - existing code uses __linux__, but I'm not clear on how that works with OSX, for example?
* I can't claim this actually "works" yet, because I don't know enough to configure the tap end of it properly to get networking doing something useful, but I will get there and correct anything necessary in a subsequent real PR.
* minor fixes/improvements (nw)
* Use Unicode Windows APIs, and UTF-8 for MAME
* Deal with unterminated registry string values
* Cancel any pending I/O in destructor
* Eliminates the need for the horizontal/vertical/LCD/SVG layout files
* Screens can now have orientation and physical aspect ratio specified
* RASTER/VECTOR defaults to 4:3, LCD/SVG defaults to square pixels at config time
* System orientation is applied on top of screen orientation
Automatically generated single-screen views and orientation flags in XML
output now work correctly for systems with multiple screens in different
geometries/orientations, e.g. housemnq, rocnms, stepstag, or netmerc.
The "core rotation options" only interact with system orientation.
Allowing multi-screen systems to work well with one monitor per emulated
screen is a complex topic. System orientation also affects the GFX
viewer while screen orientation doesn't. The orientation displayed in
the system selection menu is from the system orientation.
Let me know if I've broken any systems or use cases.
Also, add save state support for std::array/C array nested to any depth.
* rewrote most of the execution for my tlcs870 core

* note updates (nw)
* address concerns, const qualify more things where possible (nw)
* more const (nw)
* oops (nw)
* consistency (nw)
