"Greg_" ??? You !?!? Oh, you don't know how much I would like to kill my
self right now !!! I have been looking this information all over the world,
and I have even tryed to contact Yamaha in USA without any help. Kari
Lammassaari (ACADEMY) has been looking this information too about 10 years,
and then you appear to be in this mailing list with us and with all this
information ! I could have asked this question here long time ago, but I
just didn't belive, that anybody has this information here, just this close.
AARGH !!!! Thank you, thank you, thank you, thank you, thank you !!!
You have just helped us a great step forward, finaly I can get some real
cool sounds out of my MSX tR !!! I think, that this is much better music
expansion, than some MSX-MUSIC or MSX-AUDIO. Maybe I can make some own music
editor or FM-Pac emulator or MBM replayer or...
Ok, I try to calm down... Because rest of you don't even know where this all
started, then here is the original message :
----------------------------------------------------------------------------
I was looking information about Yamaha FM-Sound Synthetsizer Unit II (SFG-05)
that was included also to Yamaha CX5M MSX computer and I founded out,
that you can maybe help me.
I have done some research, and I have allready founded out how to read
keyboard (YK-01 or YK-10), but I still don't know how to produse a sound
with this DX7 compatibble FM-Chip.
So, I would be wery grateful, if you could give any information about this
FM-BIOS or addresses #3FF0-#3FF6, that controlls I/O of this module.

This is no brobblem. I have this device allready, and I have monitored this
ROM quite a much. Anyway I have not getted any sense about it. (Too much CALL
commands jumping around etc.) :-(
BTW I have founded a small bug from the FM-BIOS, that makes life easy for
Panasonic MSX tR and MSX 2+ users. As you have maybe notised, both modules,
this and FM-PAC uses CALL MUSIC command. When you type CALL MUSIC in
these computers, FM-PAC handles this command, and it newer goes to this
sound unit. Anyway, if you type forexample CALL MUSICA then FM-PAC will not
regognize it as a command, and it will pass it trough to next device. This
FM-BIOS does not check this last letter at all, and the proggram will start !

Name of this chip is very important, for finding information. I did not have
even this !

I guessed these ones right, and I managet even to get some noice, but without
any reasonabble method. :-)

Yeah, this is very clear to me. If someone want's sources, I can send
them. Maybe they will be added to my www-page too in the future.
I'll try to do whole proggramming manual for this module, as soon as I have
enough time to get some sense about it.

Great ! I just can't view these .PDF files :-( Maybe I can go to look them to
my friend soon.

Pictures again :-( Well, anyway I'll download them just after sending this
message.
