Marked as non-working because the correct terminal isn't emulated, so we
can't fully verify that everything works. Run it with '-ser terminal' to
see the garbled output.
This also adds the clone Grundig FL-100.
* Added new driver: HP 3478A Multimeter
WIP, machine not working, skeleton, highly incomplete. Compiles, that's
about all.
* hp3478a: implement ROM banking
code runs "properly" at least to the CAL RAM check (fails, RAM not
implemented)
* hp3478a: some IO work
Interpret CS lines for external accesses (GPIB, CAL RAM, DIP switches).
Also, remove MCFG_ stuff
Also, use logmacro.h stuff
* hp3478a: partial emulation of LCD
The main CPU has a serial link to the LCD module. This WIP splits
commands and data mostly successfully (still some bogus shifting which
would be fairly easy to ignore). None of the commands are implemented
yet, and no actual display is generated yet.
Includes unrelated tweak : only change bank when the A12 line changes.
* hp3478a: added LCD rendering !
code shamelessly stolen from tranz330 and roc10937 drivers.
Not clickable yet.
* hp3478a: implement CAL NVRAM
Finally. IO mapping has provisions for the DIP switches as well as i8291
GPIB interface registers.
* hp3478a: improve LCD rendering
Remove some artifacts: with the LCD "not selected", some data is sent on IWA (probably
to purge a shift register ?) but was parsed with the last m_lcdiwa
state. Reset this everytime PWO is deselected.
Also parse decimal point, comma and "all segments".
* hp3478a: implement keypad
* hp3478a: CAL switch to write-protect NVRAM
* hp3478a: implement DIP switches
* hp3478a: fix self-test reset freeze (missing WDT)
There is an external WDT counter that is periodically reset by the CPU
in normal operation. When forcing a reset from the front panel, this
counter is allowed to overflow (20th bit, clocked at Xtal / 15), giving
a reset time of about 1.3s.
4D/20 is a Personal Iris. The IP15 ROM in this skeleton belongs to the IRIS POWER Series model 4D/4x0, so I've assumed that's what the driver should be for.
-mips3.cpp: Various changes: [Ryan Holtz]
* Added an #ifdef to display DPRINTF calls from the SGI O2 PROM.
* Switched R4000BE/LE, R4400BE, R4600BE, and R5000BE to 64-bit data bus.
* Fixed a bug that caused a crash with 64-bit data bus and the DRC.

-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.
* [R9751] (Squashed) Early work on SMIOC emulation

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.

Author: Stephen Stair <sgstair@akkit.org>

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.
A driver for machines made by MIPS Computer Systems, which used MIPS R2000, R3000 and R6000 CPUs and ran RISC/os (a port of UNIX System V Release 3). Initial focus is the RC2030 headless workstation. As of this commit, it gets part-way through its I/O processor diagnostics with output to a serial terminal.

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.

Four Trax (Japan) [ShouTime, The Dumping Union]
note, one of the gfx roms in the MAME set has an 'fx2' label, it should be verified.
also replaced the ROMs for the fourtraxa set, the old ones had a 0x00 fill instead of a 0xff fill but were otherwise identical, it's a weird mod of the World set that hides most of the advertising banners, replacing them with generic ones, presumably for legal reasons?
- Add and identify some extra IOC firmware revisions (v1.3 from Bitsavers)
- More descriptive names for ROMs of latest IOC revision (from Bitsavers)

Merged with strnskil.cpp, with modernization and cleanups. (nw)
Add MCFG_SCREEN_RAW_PARAMS. (nw)
Added coin counters to markham, strnskil, banbam and clones.
* proposal: move z80daisy* to devices/machine
Seems to me this is a machine, not a CPU? Main reason was to stop the Z80 CPU from being dragged into systems that don't have one just because they use a Z80 family peripheral.
* missed this one (nw)
* missed a spot (nw)
* interpro: slotify mouse (nw)
Needed to make the mouse a slot device to enable it to be connected to graphics boards under development.
* add validity check (nw)
* bt45x: new devices
Basic implementation of various Brooktree RAMDAC devices. Two of these (bt457, bt458) are used by InterPro graphics boards currently under development, the others are unused/untested at this point.
* bt45x: tweak descriptions (nw)
Start replacing special device macros with additional constructors,
starting with ISA, INTELLEC 4 and RS-232 buses.
Allow an object finder to take on the target of another object finder.
(For a combination of the previous two things in action, see either the
INTELLEC 4 driver, or the Apple 2 PC Exporter card. Also check out
looping over a device finder array to instantiate devices in some
places. Lots of things no longer need to pass tags around.)
Start supplying default clocks for things that have a standard clock or
have all clocks internal.
Eliminate the separate DEV versions of the DEVCB_ macros. Previously,
the plain versions were a shortcut for DEVICE_SELF as the target. You
can now supply a string tag (relative to current device being
configured), an object finder (takes on the base and relative tag), or
a reference to a device/interface (only do this if you know the device
won't be replaced out from under it, but that's a safe assumption for
your subdevices). In almost all cases, you can get the effect you want
by supplying *this as the target.
Eliminate sound and CPU versions of macros. They serve no useful
purpose, provide no extra checks, make error messages longer, add
indirection, and mislead newbies into thinking there's a difference.
Remove a lot of now-unnecessary ":" prefixes binding things relative to
machine root.
Clean up some miscellaneous rot.

Skannerz TV [Sean RIddle, Peter Wilhelmsen]
This will need the communication protocol with the barcode scanner unit reverse engeering (the scanner unit has it's own MCU that isn't dumped and for which we have no method of dumping) this also probably means it will need improvements to the general vii.cpp handling of interrupts and serial ports (which Cricket needs too)
also made rainbow islands extra a parent, since it has it's own game code, own c-chip and is generally considered a semi-sequel rather than a bugfix / revision of the original game.
(best I can tell behavior matches the differences between original and extra that were present in the simulation at least, but obviously the real chip could be hiding more secrets)
