  1. HELP ID ME ! - Irem M62 Sub Board

    It has been done already, here.

  2. CPS1 boards from AliExpress

    They aren't unobtanium either, very easy to find.

  3. CPS1 boards from AliExpress

    Wrong amp and fake chip circled. If it's works and you're happy then great but bootlegs for less money work too or playing it in mame also works. Guess I'm just a purist and would be swapping both those parts for originals if it were my board. :) You might find some sounds don't sound quite...

  4. CPS1 boards from AliExpress

    The wrong amplifier is bodged in place and they've replaced the surface mount sound chip with a fake one on your A board.

  5. Mario Bros intro screen…blooming issue?

    I think they all do it, mine certainly does.

  6. Question for the monitor experts

    How important is low resistance on tube ground (aquadag) to the neckboard / frame? I am trying to track down a video noise issue on a Sanyo 20ez and noticed the ground strapping wires on the tube are a little corroded and it's done some damage to the aquadag on the tube. Using a meter it's still...

  7. Why isn't there a triple Donkey Kong FPGA?

    It's very easy to get around Nintendo copywrite issues if you make it free / open source. :)

  8. Who would you like to see come back to KLOV/Hobby?

    John (Blkdog7), Adam (OneCircuit) and Arcade Impossible all seemed to vanish at the same time, I suspect they killed a hooker in Vegas and made a pact to keep their heads down after that.

  9. Does anyone have a DEAD 3D1000 or 3D1001 from a PP-7A or PP-7B - I'd like to take one apart and try to reverse engineer it

    We need to get the 3D1000 done now. ;)

  10. Does anyone have a DEAD 3D1000 or 3D1001 from a PP-7A or PP-7B - I'd like to take one apart and try to reverse engineer it

    The caps and resistors are surface mount (and tiny) :LOL: but yeah I copied the original design.

  11. Does anyone have a DEAD 3D1000 or 3D1001 from a PP-7A or PP-7B - I'd like to take one apart and try to reverse engineer it

    Pcbs finally arrived and I assembled one, I decided to use my DK power supply because it needs recapping anyway. I open it up and...... what the hell is this 3D-1001B? B? hmm it has pin 1 on the right unlike the A which has it on the left.... maybe the same as A with reversed pinout? I guess...

  12. Nintendo (Sanyo 20ez) Monitor waves...

    @DIYPinball did you fix this? was it the LA5112? I've got the exact same problem.

  13. Sanyo 20EZ purity issue?

    Oh nice, what did you use to display the last image? TPG?

  14. Sanyo 20EZ purity issue?

    I've just fully recapped a Sanyo 20EZ and replaced all the pots and it looks so much better than it did but I've noticed what looks like a purity issue in the bottom right corner. The first picture of Mario is what he looks like in bottom left, top left and top right corner but in the bottom...

  15. Mario Bros Hum

    Any updates on this? sounds like a mario bros board issue if multiple people have found popeye pcbs don't have the hum in the same cabinet. I had a 4 stack DK with terrible hum and it was very much the board at fault as outside the cabinet on the bench with a switcher it still had hum.
