Hello,

i recently got a Panasonic A1FX MSX2+.
This model lacks of FM chip and other circuitery, but there is room on the board for the missing ICs.
Does anybody tried to add FM sound to this model?
Are the schematics available anywhere?
Maybe somebody can take some pics of a WX or a WSX PCB?

Hey!
It is allways nice to hear that MSX is still alive in Korea.

Thank you for the pics, but i am afraid that Turbo R board is different from Panasonic MSX2+.
I am looking for schematics or somebody who installed the "missing" parts to make FM work. I wonder if the FM chip and sound mixing circuitry is enough or it needs more chips...

By the way, do you have any tape of any game in "korean edition". In Spain (i am spanish) there is a group that is doing "tape preservation" and are looking for rare tapes...

I found MSX2+, Turbo-R FM-SOUND chip is that YM2413(OPLL).
Chip maker is YAMAHA.

it's not only the chip used in 2+ and turbo r. but also the one used in the FM-PAC. Or actually all msx-music extentions

actuall does the chip exist in turbo-r ? Is it not embedded in something else in turbo-r, like turbo-r dont have any original psg-chip.
