Sound Box SFS-T1 setup manual

Hello here!
I own a SFS-T1 sound box, here is the setup manual for SFS-T1 and SFS-T2 parts.
I don't have a lot information about this stuff and SFS-T2 is missing for working.
It seems to be a very early sound developpement system for Super Famicom since 89' year is indicated on it and working with NEWS computer.
All information about this stuff is very welcome ;-)

 

You have some pictures you like to share with us?

 

It looks like it would be pretty easy to interface to - it's just got 4 8 bit I/O ports on the connector (presumably corresponding to $2140-$2143 in the SNES memory map).

 

Yes I will share the photo to inside, it will be more interesting!

You're right, the interface seem to be very simple.
