Let's continue with pictures !  Wink

TAITO Missile-X :



PCB is a TTL-only board. There's no CPU.
This is my biggest TTL-only board !
All chips references where obfuscated using "heavy duty" black pen.
Small boards on the left are analog sound boards.
Board with heat sink is power regulator.



Board(s) being repaired (as usual) :

A friend gave me those "4 bit hex display" DIL311 from Texas Instrument  Kiss
They're connected to the 3 x 4-bits-latches of CCPU's main accumulator "A"

Here are some pictures...  Smiley

Missile Command :



Missile Command PCB repairing : dumping fuse-PROM @ L6


Missile Command PCB repairing : logic analyzer in action...
(stupid old 2732 EPROM that have a 1-day data life !!!)
Home-made PCB is some electronic tool to have analyzer trigger at some point in the 6502 code execution without monitoring the address bus (not enough analyzer channels).



Other pictures to come  arrow ...

Hello.

I just registered here.
No (sticky) thread "present yourself here" was found, so this post is to introduce myself.

I'm Fabrice, 39 years old, living in France.
Some of you may already know me, I'm present on the french gamoover.net forum.
No, I won't tell you I'm an arcade addict, you already guessed it !
I own about 10 ~  15 arcade games + some PCBs.
To be honest, I confess I prefer/spend more time repairing my games than playing !
I know it's crazy, but that's me...

Some of my games :

  • my beloved SEGA Quartet (a 4-players game)
    restored back to Quartet, was converted to something else

  • SEGA Space Ship (vector game, clone of Cinematronics space War)
    fixed PCB + screen
    AFAIK, my cabinet is the only one known ; I dumped the ROMs and updated Mame source code to add the game

  • VECTORBEAM Speed Freak
    fixed screen

  • ATARI HORROR GAMES Shark Jaws
    fixed screen + PCB

  • MIDWAY Wheels
    fixed screen + PCB

  • TAITO Missile-X (B&W, TTL)
    fixed PCB

  • ATARI Breakout
    fixed screen + PCB

  • ATARI Missile Command
    fixed PCB (electronic designer was really a tortured psychopath)

  • an ELAUT ufo catcher
    fixed PCB

  • DATA EAST pinball
    fixed missing columns & rows on VFD screen

  • ROCK-OLA jukebox
    fixed hardware: gripper + carousel

  • ...

I'm currently little busy, preparing my wedding (april).  Grin
I wish you a happy new year 2013 !

EDIT: forgot my Missile Command cabinet...
