Systems Promoted from GAME_NOT_WORKING:
---------------------------------------
- SBC6510 [Robbbert]

Skeleton drivers:
-----------------
- VAX 785 (LSI-11 board only) [Miodrag Milanovic]

- Elektronika MS-0515 [KokaF77, Miodrag Milanovic]

System Driver Changes:
----------------------

-llc1: fixed monitor keyboard LLC2: added speaker and annoying keyclick
 [Robbbert]

-vidbrain: Added expansion port interface. [Curt Coder]

-vidbrain: Added expansion port pinout. (nw)

-llc: modernised ; LLC2 added support for reverse video & added missing
 pio. [Robbbert]

-vk100: Some improvement to the HLE vector generator, now properly
 emulates the down counter so the "blue screen" part of the POST looks
 correct, as does the cursor width. [Lord Nightmare]

-vk100: broke the vram access logic/math out of the vector generator
 callback and into its own functions; fixed? the systat_a register to
 read the vram nybble the x and y regs are currently pointing to.
 [Lord Nightmare]

-abc800c: Added character display, promoted driver to working.
 [Curt Coder]

-pcm: connected the k7659 keyboard, fixed screen size [Robbbert]

-abc800c: Added high resolution graphics. [Curt Coder]

-abc80: Added serial interface. [Curt Coder]

-a6809: Added ASCII keyboard. [Curt Coder]

-abc806: Used correct HRUII PROM. [Curt Coder]

-socrates: document that an MCU dump is missing of the 4-bit TMP42C40P
 that decodes the IR signal from the keyboard and buffers the 'second
 stage' of the keyboard input. Changed code slightly to reflect this.
 [Lord Nightmare, Balrog]

-z9001 : added 2xpio, ctc, daisy-chain, beeper-sound, cassout
 [Robbbert]

-v6809 : various video improvements. [Robbbert]

-abc80: Refactored legacy code, moved DOS ROMs to ABC bus DOS card,
 added BASIC V1 dump, added ABC 890 bus expander device. [Curt Coder]

-abc80x: Refactored legacy code, cleaned up keyboard interface, added
 ABC894 bus expander device, added ABC 55 keyboard for ABC 802.
 [Curt Coder]

-vt100: add the GPO (aka VT125 mono board) roms and proms as a mix of
 NO_DUMP and copies of the vk100 ones where identical [Lord Nightmare]

-vk100: further comment updates, got rid of LASTVRAM in favor of doing
 a single read at the current nybble pointed to by the X and Y
 registers. [Lord Nightmare]

-vk100: Implemented baud generator LUT for i8251, not hooked up yet;
 added RTS callback which doesn't seem to work yet. [Lord Nightmare]

-vk100: Doing further vector rom tracing with a meter on the board
 using the vt125 schematics as a guide, figured out what all the vector
 rom pins do (except perhaps D LOAD). [Lord Nightmare]

-vip: Added VP-620 ASCII keyboard cable, VP-570 RAM expansion board,
 and VP-575 bus expander board. [Curt Coder]

-plus4: Rewrite of the C16/Plus+4 driver with improved memory mapping
 and cartridge support. Refactored the Commodore 1551 floppy drive to
 connect to the expansion port. [Curt Coder]

-vk100: Documented all the inputs and enables of the RAS/ERASE prom
 through tracing. Documented that the MSB bit of the SYNC prom is ...
 SYNC. The VT125 Schematics were invaluable for this.
 [Lord Nightmare, Al Kossow]

-sbc6510: Connected up the keyboard and added ay-3-8910 chip [Robbbert]

-vii: Fixing some warnings. Not 100% sure of the intended
 functionality, but IRQ & IRQ_MASK & line seems probable and seems to
 work. [MooglyGuy]

-c64: Fixed C1541 and FSD-2, added Dolphin DOS 2.0 and
 Professional-DOS V1 hardware. [Curt Coder] 

-plus4: Added SID card emulation. [Curt Coder]

-c64: Emulated the digital read circuitry of the Commodore 1541 disk
 drive according to the long board schematics. This will allow
 independent setting of the bitrate of incoming data and the sample
 rate. Passing more advanced copy protections require a cycle exact
 rewrite of the 6502 and VIA, but this is the first step toward proper
 emulation. [Curt Coder]

-vip: Added VP-700 Tiny BASIC board. [ekeefe, Curt Coder]

-c64: Added support for per-byte speed zones in G64 images.
 [Curt Coder]

-sacstate: Added comments. Fixed input ports. [Robbbert]

-hr16: Hooked up LCD controller and added keypad inputs. [Sandro Ronco]

-rainbow:
 * Get closer to LK201 emulation [R. Belmont, Lord Nightmare, Balrog]
 * Add documentation for system error codes and diagnostic LEDs
    [rfka01]

-vboy: various driver improvements [Angelo Salese]

-vboy: preliminary audio hookup [Richard Bannister, Gil Pedersen, R. Belmont]

-x1: added support for old TAP format to the driver, so that all newly 
 added tapes work (high sample rate tapes are still not supported, though) 
 [Fabio Priuli]


Software Lists:
----------------
-pico.xml: added new Jpn dumps [TeamEurope] 

-pico.xml: started documenting PCBs and ROM labels [TeamEurope]

-x1_flop: first round of new dumps [Starscreamer the 2nd]

-x1_cass: some more new dumps [Starscreamer the 2nd]

Source Changes:
----------------
-new device k7659 keyboard; modified LLC2 to work with it [Robbbert]

-k7659kb - added more keys, added port_char, added return value when no
 key pressed [Robbbert]

-terminal: Replaced internal keyboard with the Ascii keyboard, since
 they were identical. [Robbbert]

-nscsi: documentation [O. Galibert]

-rp5c15: Initialize at power-on (makes the x68k boot reliable) [O. Galibert]

-roc10935/7: correct an error in the lookup table for the '7' character [Lord Nightmare]
