taito fast io and 6 buttons

[lolosaka]

hello guys,
please help me, im looking for some information:
i bought the "taito fast io universal pcb" (j9100633a )
but unfortunately, i can use only 4 buttons.
then a friends explained me, that is normal.
j9100633a is the board hardware, and the sticker k91x1234c is the firmware revision, this depend of the game made for.
and we cant change the firmware so far.
so im looking for the good one now. if someone know which firmware is ok i will be very thankful.

Also, i know the "taito fast io amp" (j9100634a) is the easiest solution but price of this board is too high..

thanks a lot

Refer to this post https://www.arcade-projects.com/threads/fast-i-o-pcbs.8109/#post-251921

I went through this last year.

Long story short, the K91X1252A is the only universal fastio pcb that allows 6 buttons (that I'm aware of). The 1234* is only 4 buttons.

If you need 6 buttons, you're best to search for 1252A or the FastIO with the JAMMA edge.
