There was not much progress in 2011. I've been lately very busy with my work projects ( this and this one). But at least i've prepared a TO-DO list for 2012 ;) :

1. VEGA ( Olympia, 1982 )

I have recently got Vega PCB. Special thanks to Mark Frisbee for help.

Unfortunately board has few faults ( no sound, gfx glitches ) and inverted colors (like early Nintendo boards). Theres a couple solutions for the latter problem. I have decided to mod the pcb a bit and invert the digital signals before the DAC (made of resistors). Here's a video from attract mode:



So, next step is to emulate the game :)

2. TIME ATTACKER ( Shonan, 1980 )

Currently i'm making schematics of video section. It's similar to classic Pong discrete logic, but a bit more complicated (game has Z80 cpu). TA is a breakout clone, with special add-ons like oil zones and moving enemies ( btw : background color - blue or black - is selectable with a jumper on board ):



3. WHEELS & FIRE ( TCH, 199? )

Not much about this one. I'm in the middle of MAME driver rewrite process (based on game sources i got from the author).
