    ANNOUNCEMENT - MMS1 - A 16 in 1 MULTI FOR JALECO MEGASYSTEM1(A) FROM CAIUS + HAMMY

    Looked for any trace damage with the scope and the multimeter and everything is ok. Since the game starts if I slightly lift the CPU from one side I think it's a bad contact between the header and the CPU. Maybe I'll try the 12mhz CPU on those headers before desoldering them again now that I...

    ANNOUNCEMENT - MMS1 - A 16 in 1 MULTI FOR JALECO MEGASYSTEM1(A) FROM CAIUS + HAMMY

    Since I don't have any other components yet I decided to desolder the CPU ant put some headers in the meantime. Unfortunately the old CPU pins are not very straight (like all desoldered components) so the CPU probably isn't making good contacts and the game doesn't boot.. If I lift a bit the CPU...

    ANNOUNCEMENT - MMS1 - A 16 in 1 MULTI FOR JALECO MEGASYSTEM1(A) FROM CAIUS + HAMMY

    Initially I wasn't thinking that the other CPU is for the sound and there is no point on upgrading that too :)

    ANNOUNCEMENT - MMS1 - A 16 in 1 MULTI FOR JALECO MEGASYSTEM1(A) FROM CAIUS + HAMMY

    is there already a suggested HW list to overclock the MM1 or still in testing? we'd need (other that the EPROMs for the multi): 2 x MC68000P12 2 x sockets for the CPUs ?? x 10 Mhz Crystal? are there other parts? how many crystals do I need? I'm not going to order now since there is no rush at...

    Retro Hardware Capacitors LISTS

    Maybe someone before you already recapped the board partially but with different values, can you see if the solder joints are from the fabric or not?

    Jaleco Mega System 1, testmode?

    The p1 button 2 was always pressed due to a broken JK-03, I've bought and installed 3 repros from @caius and now I'm able to pass the screen by pressing p1 button 1 and run all the tests!

    Jaleco Mega System 1, testmode?

    I got this board today and trying to figure how to enter in the test menu to see if everything is working (the game seems to run fine from the attract mode). I've tried some combos at startup but only holding the service button I get the squares pattern but nothing else. Am I missin something?

    My F3 sometimes doesn't power ON

    sorry for the late reply. I've used panasonic and nichihon for the recap. I've tried to move a little bit the potentiometer and now it seems to boot every time (need more tests but tried to boot like 10 times, one every 10 minutes and it always booted)

    My F3 sometimes doesn't power ON

    I'll try to measure it but it has the glue on it, (don't know if it's present from the production line or not). I never touched it since I already knew that wasn't an audio potentiometer when I bought my 1st f3.

    My F3 sometimes doesn't power ON

    Hello, I'd like to ask if there is a possible solution for a long time problem with my F3 setup. I have a recapped Taito F3 motherboard with the multi that sometimes if I power it up it does nothing (no fan spinning, no video, nothing). If I discharge the board and the PSU (without changing any...

    Namco NA1/NA2 Repair Tips

    I want to share this little repair log since I was finally able to fix my headphones audio on my NA2. First thing I swapped the potentiometers with the ones suggested by @Hammy and the old ones were very very rusted. Unfortunately with the new potentiometer the HP audio wasn't still back. Next...

    ZN1 Bios <V2> board arrives!

    I'm sorry but I was misunderstood I don't mean the gnet games. But since the gnet is composed by 3 PCBs and the main board is a Sony ZN2 (if I'm not wrong) I was asking if the mainboard can be used with the proper romboard for a future product from you :)
