    WTB Data east BAC06 chip. 40 eur -> 50 eur

    No I don't. But a lot of deco-games from that era (mid - late eighties) seem to have it. Pocket gal 2, bad dudes (aka Dragon Ninja), hippodrome (aka fighting fantasy), birdie try, heavy barell, robocop, midnight resistance, cobra command ...

    WTB Data east BAC06 chip. 40 eur -> 50 eur

    I am looking for a working deco BAC06-chip. It has to be the surface mounted version. A broken or working board with named chip is also of interest. I'm ready to raise my bid to 50 eur but shipping to Sweden (post code 35595) must be included in this price.

    FOUND Namco system 23 main board

    I have a broken time crisis 2. Need a new "main board pcb". Got a working mem board and rom board (TSS2 ver. B). So just the main board will be sufficient. MUST be system 23 (NOT super system 23, not gorgon) I'm ready to pay 150 us for a working board but that must include shipping to Sweden...

    Special PCB investigation (SCI-repair)

    The Guru-pcbs have arrived. I soldered a socket on top and square pin headers below. (I've ordered machined headers). Burned the rom on a 27c400. Power it up and is greeted with a hissing and corrupt sound. Not good. Remove the adapter but problem persists. Getting nervous but fix was easy...

    Special PCB investigation (SCI-repair)

    This was easy! I just changed all the tmm2063, put in a new ROM (C09-01) and now the game runs almost perfect. All weird behaviour that I feared was one of the many customs were just cheap ram. Sound is working. But some samples are corrupted. These are stored in 834100 mask roms and there is...

    Special PCB investigation (SCI-repair)

    So. I guess I can to answer my own question. NO. That RAM check in test menu is not reliable at all. Even though I've piggybacked all RAMs the game wouldn't start. But piggybacking doesn't work if there are pins stuck high. And there is always the risk of bad contact. Therefore I changed all...

    Special PCB investigation (SCI-repair)

    I'm stuck with my SCI. And would appreciate some help. There is no sound, graphical errors and lacking sprites ... But first things first... By replacing one TMM2063 RAM and a PAL (c09-19) the game boots. I see the taito logo and a scrolling machine typed letter. Then when it's supposed to...

    Fixing a Chase HQ S.C.I PCB (Taito Z system)

    Mypinballs. We seem to have same symptom. Today I got my SCI to boot. Problem was a faulty TMM2063 which I think is used for the main program. That is why my board booted over and over, it read empty or corrupt data. Have you tried to piggyback the RAMs at the main program ROMs? (Still some...

    Greeting from Sweden

    I've always loved arcade games. As a boy I never got any money to play though. But it is never too late to have a happy childhood.

    Fixing a Chase HQ S.C.I PCB (Taito Z system)

    I got a cab from Electrocoin. Their power wiring is Jamma except that there is 13v instead of 12 on the solder side on the plug.
