    CPS1.5 conversion help

    First, if there is a guide someplace else(looked all over this forum) that may make it alot easier figuring this out, please post where it is. I have most of a Slammaster CPS1.5 pcb set except for the B board, in which I am going to use a SF2 (91635B-2) pcb in it's place. This Slammaster was...

    Knights of the Round C board question

    OK, so I was going through some old boards and found (2) Knights of the Round pcb's w/o C boards. Back in the day, I de-suicided them as rom 23 has been blanked and rewritten. I received my battery backed B-21's in the mail today so I thought I could throw one of them on this board. Anyway...

    PCB part identicification

    I have a Joe and Mac pcb that I received awhile back that doesn't boot. Infact it's kind of weird on my test rig. Upon powering up it shuts my test rig down, as if there is a power fault, or something. The pic shows (3) components (outlined in blue) that I am missing from the pcb I describe...

    What are the best TV's suited for our arcade cabs?

    I made friends with a local electronics recycle guy who happens to run into a number of old tube TV's. He's willing to put aside whatever I want, but what am I looking for when it comes to old TV's? Not including the Sony B/PVM's, I have heard Sony Trinitrons are up there. Other than that, if...

    Sound issues on Super Neo 29 cab

    I have a Super neo 29" that's practically new, so I don't know that it's something physically wrong with my cab, but my question is if there is different wiring within these MVS cabs that is different than a regular jamma cab in regards to audio? I have tried a number of pcb's with varying...

    Chinese eproms

    I recently received an order of AM27c4096 eproms from China. They look like new, but my guess would be they are not. I have seen how they can take them and make them look like new, etc. Anyway, my problem is that they will not write. I have erased them completely twice. I run a blank check and...

    SNK P.O.W audio amp identification

    I need to replace this 12 pin audio amp. The labeling stamped on the chip is pretty much wiped off, but 13001 is stamped on the pcb next to the chip. I can't find this chip or any information on it. Is there a proper part number/name for this part so that I could find a replacement? Perhaps...

    SF2 CPS1 B board player 1 button issue

    Can any of you board fixers tell which chip(s) on a SF2 Hyper Fighting B board has to do with the controls- more specifically the Player 1 button. Initially I swapped "A' and C" boards because I didn't know where the chip for controls were located, but narrowed it down to be on the "B" board...

    Sunset Rider from 4 player to 2 player

    OK, so I have a 4 player Sunset Riders pcb that I converted to a 2 player version by burning and swapping 2 eproms at location 8e and 8g. The thing I can't figure out is that I did this for another guy on his 4 player pcb, same eproms I did for mine, but his does not work. Apparently once...

    -5 volt in Blast City and Super Neo 29

    Can anyone suggest the best way to attain -5 volt in both of these cabinets? Neither of the harnesses have -5 on them, so I am assuming that the power supply doesn't output it? I have a number of pcb's that utilize -5 and sucks that I can't play those in these cabs .Thanks for any advice.

    Shinobi revival help

    I have a Shinobi pcb that I aquired and am assuming has died. I am still awaiting the arrival of my adaptor. In the meantime I was planning on taking care of the battery, etc. I planned on replacing the NEC block with a Z80 and the Hitachi FD1094A with a 68000. Now in all the research I did, the...

    Supergun + jamma harness extender=no audio

    I have one of those Retroelectronik gamer supergun units sold in the UK and for whatever reason, I don’t get audio when the jamma harness is connected on my test bench, but do when I plug the pcb directly into the supergun. I have tried 2 different harnesses with the same result. The harnesses...
