MESS v0.147 is released. MESS is an open source project which documents the hardware for a wide variety of (mostly vintage) computers, video game consoles, and calculators through software emulation, as MAME does for arcade games. As a nice side effect to this documentation, MESS allows software and games for these hardware platforms to be run on modern PCs.

[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.

[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.

Some work still needs to be done to beep.c since the phase needs to be reset in such a way that keyclicks work consistently, in addition to beeps. [Lord Nightmare] -vt100: Added missing dot stretching to the DEC VT100's dc012 emulation. See EK-VT100-TM-003 page 4-76 for a description. Note the stretching takes place after the character rom but before invert or other attributes.

[shattered] -iskr1031, ec1841: split machine descriptions from pc16, remove hacks from pc16 and ibm5550. [shattered] -ec1841: mirror chargen memory at b800:1000 -- fixes video test 501 on TPS (diagnostics) disk. [shattered] -ec1841: implement memory controller (only for 1 board yet), no support for remapping banks inside the board. Memory test in POST passes. [shattered] -vk100: WIP: preliminary gfx rendering; hooked up the i8251 interrupts. Corrected dipswitch locations. [Lord Nightmare] -vk100: Initial implementation of the vector generator. Rather buggy, and not really readable yet, but it definitely shows something on screen, and you can type and see things change! (and you see a blinking cursor too!) [Lord Nightmare] -vk100: further improvements to the vector generator, still not completely correct. [Lord Nightmare] -vk100: FINALLY fixed the vector generator. Display looks relatively sane now. Fixed shift and capslock being reversed and added port_toggle to capslock. [Lord Nightmare] -vk100: preliminary direction support for basic vectors. doesn't quite work right yet. [Lord Nightmare] -vk100: Add more debugging defines, remove some unneeded code, and added more comments to TODO and to some registers. [Lord Nightmare] -vk100: vector generator uses "real" timing instead of drawing the vector instantly. [Lord Nightmare] -vk100: update comments to reflect that the pr1 prom is clearly the VECTOR ROM. Add notes about what each address bit does or is thought to do. (the tech manual documentation is lousy, but is better than nothing). [Lord Nightmare] -geniusiq: Added PCB layout for the German Version. [TeamEurope] -vk100: minor cleanups to variable names, documented as much of the address info of the sync and direction proms as I could figure so far. [Lord Nightmare] -vk100: vector timing callback rate is now definitely correct; the tech manual had an annoying error which made this hard to figure out. [Lord Nightmare] -vk100: figured out bits 3,2,1 of SOPS register and implemented blinking and documented serial multiplexer based on these findings. Also fixed a stupid bug in the display code which broke the reverse video bit. [Lord Nightmare] -vk100: properly hooked up dipswitches through the SYSTAT_A register bit d2. Got rid of some dead palette code. [Lord Nightmare] -vk100: Fixed the weird ordering of the dipswitches, so everything now controls what it should. [Lord Nightmare] -vk100: Add the two previously-missing PROMs (not hooked up yet); Update notes a bit, correct location for the main roms according to tech manual (it turns out you count from the lower right corner upward, not upper right downward). [Lord Nightmare, Balrog, Andy V.] -vk100: Comment wrangling and some analysis of the newly dumped proms. Still some work to be done here especially on the vector prom. [Lord Nightmare] -vidbrain: Fixed graphics corruption in Lemonade Stand. [Sean Riddle] -vidbrain: Fixed memory map, improved colors. [Sean Riddle] -mc1502: preliminary floppy support. Still not functional [shattered] -pc: fixes the sound in Arkanoid, which doesn't use the 8253 at all.

Note the intv1 exec.bin still needs to be split to the two separate roms that the real hardware used. [Lord Nightmare] -intellivision: enabled the c000-cfff area for cart rom access; while no commercial carts used this afaik, at least one homebrew cart does and won't work without it. (actually this was in the previous commit by accident) Corrected the manufacturer/name of the Sears Super Video Arcade. [Lord Nightmare] -thomson: Performance improvements and bug-fixes: more efficient bank switching, fixed video update (Mach 3, Sparce Racer, HCL), fixed game PIA port B, fixed side-effect in debugger, fixed MO6 cassette.

[Curt Coder] -sc3000: Moved the fake BIOS to cartridge software list. SC-3000 does not have an internal BIOS, instead a BASIC or other cartridge needs to be plugged in manually. E.g. "mess sc3000 basic3" [Curt Coder] -vip: Connected the byte I/O and expansion ports. Refactored the VP550, VP590, and VP595 to implement the expansion slot interface. [Curt Coder] -vip: Added beeper on/off switch, and VP585 board. [Curt Coder] -ti99: gromport redesigned, now offering three slot options "single" (default) / "multi" / "gkracker" determining the set of cartridge slots (cart or cart1/2/3/4). Cartridge insertion may be set to trigger RESET or not. TI consoles now have a dedicated RESET line, connected to the RESET input of the CPU and VDP. [Michael Zapf] -DEC VK100/GIGI documentation update; document two missing proms, correct (I hope) IC locations (until we can get schematics) using the DEC system of counting from the top right corner downward and shifting one column to the left at the end, and documented the (sometimes barely/illegible) markings on the proms.
