    Try a decoupling cap next time, it sometimes helps with those issues.

    i used a pickit2 clone with pickit 2 v2.61 software and upon reading a 12f629 blank chip i was gettin 3FFF instead of 0FFF. i then tried other 3 different blank 12f629 and still all read as 3FFF. i then imported and wrote mm3 hex to one and it verified ok. so i guess its normal on pickit 2 v2.61 and 12f629 pic chips. today i installed one pic (mm3 usa hex) on a psone and all backups/imports boot fine

    The software is different so 3FFF may be perfectly fine. My guide was for PICPgm. Glad your chip is working :)

    Hello guys,
    I've programmed a Mayumi 4.0 for my PSOne. I soldered it in combination of some solder points.

    The chip actually works, but not always. Mostly after switching it on. The thing with the open lid does not change any behavior.

    Anyone got some tips for me how to fix this?

    Hello LeHaM,
    PAL
    PM41-2
    Mayumi 4.0 programmed with PicKit2 via MPLAB X
    12F508

    I have to admit I did this 2-3 month ago. I combined some install diagramms as there haven't been any for PM41-2

    Thanks for any help

    Are there any alternative solder points for 2 and 4? For Mayumi4.0

    What are the benefits of OneChip? Solder points are different, arent they?
