    NOS CPS-B-21's Available

    The B chips were also prone to failure. NOS should theoretically last as long as those installed at the time of manufacture - 15+ years. Purely speculative, but as long as some operational diligence is exercised (i.e. voltages ensured to be within range), they'll probably last longer.

    NOS CPS-B-21's Available

    Howdy all. I got notification from a chip supplier who I previously purchased some nos b-21's from, that they have more in stock. He's quoting $33 per piece, not including shipping. I still have a few on hand, dont really need to spend money needlessly, but putting it out to the community...

    Not sure what that means. Typically, select is mapped to coin. In the case of this adapter, it is neo pin 2.

    CPS A-Board Differences

    I don't recall offering any guarantees or warranties. Just summarizing the experience and opinions stated by others, including at least one MAME dev (who stated the 68k's overclock fine), and as well as my own experience. Any modding comes with the caveat of "proceed at your own risk" and...

    CPS A-Board Differences

    Not true. The 10mhz 68k' overclock just fine. Quite a few in the community report upgrading their 10mhz boards with no issue. Also @PascalP can you provide some video evidence of benefits seen on something like sf2:ww big combos on a 12mhz board? We saw that sf2hf runs faster on a 12mhz...

    ZN2 pcb problems

    Then get a logic probe and start probing for floating pins. Dont think I've seen schematics for these boards, so you'll have to use data sheets for off the shelf logic chips, and trace out any floaters on proprietary chips.

    Final Fight CPS1 problem with sound effects and musical mix and overdrive

    ^That. I've repaired quite a few A board sound issues by tracking down floating connections. Cold solder joints once or twice, but more frequently it is severed traces, the cause of which cannot be found and have to be repaired with wire.

    Another A-board failure, assistance requested!

    You might want to check the voltage from your power supply. Could be a root cause here. should be max 5.1v as measured at B board chips.

    CPS-1 'A' Board Repair - As Simple as Replacing the Custom

    Nothing too in depth or detailed about this repair. I started with replacement of the CPS-A-01, and that's all it took. Looks pretty bad on the surface, and like it could be any number of things, but as we know, it's almost always the custom chip that's at fault. The symptoms: Repaired...

    CPS1 graphics error

    Part of the problem could be the chunk missing off the corner of the C board custom. And/or whatever forceful impact caused that damage likely caused other damage But, as with every other thread on here asking about graphical problems, the most likely culprits are one or all of the following...

    Replacement for Ferrite Beads on C board?

    The fb looks to stil be in tact, so shouldn't be your issue. Do you have a known good set you can use to swap parts? Check the pal's. If those are good, and theres nos signs of nicked lines, it's probably the b-21 that has gone bad.

    You were testing CE? This is HF. :) But that makes it all the more interesting, in my opinion.

    CPS A-Board Differences

    @Nimmers - answering your question from the Australian roll call thread, which answer seems more appropriate here. Just captured sf2hf running on a 10mhz A board and a 12mhz A board, just simply letting the timer run with 1P and 2P idle. From the first visible frame of the round (following the...

    CPS A-Board Differences

    I believe this is absolutely correct. I tested the unthrottled credit roll sequence, on both 'A' boards. Great results! Also adding to the extremely interesting results is the winning podium sequence just before the credit roll sequence actually runs faster on a 12mhz board, as well. When...

    CPS A-Board Differences

    Heres something that might provide some quantifiable testing. When 1cc'ing sf2hf, you get the credit roll sequence at the end. Pressing any button during this sequence causes it to run very fast (I assume unthrottled). The game will then return to normal speed when the sequence ends and it...
