T-04YBSC-x

That's what were talking about !


This is the support page of Tiido's KickÄss Yamaha Based Sound Card. Here you will find the necessary drivers and software to make the best use of this card aswell as few utilities to get things going on more esoteric configurations. I really hate web stuff so this will be pretty simple lol.

T-04YBSC is intended to be the ultimate YMF71x (OPL3-SA2x, OPL3-SA3x) based sound card out there, made with no compromises on sound quality. I got fed up with all the crummy YMF71x based cards out there and designed my own based on reverse engineering and experimentation to characterize the chips and figure out most optimal circuit and layout for them. I also wrote my own software to make use of everything in most nicest way, vastly improving on all existing solutions. Many roadblocks were on they way but I have bypassed or smashed through most of them :)

Some of the hardware features :
* Windows Sound System, mostly CS4231 compatible.
* Sound Blaster Pro 2.0, supporting most features of the real deal.
* One MPU-401 UART wired to WaveBlaster header and GamePort.
* Second MPU-401 UART wired to YMF721 based MIDI ROMpler.
* Two OPL3L, one in YMF719 and one in YMF721. Compatible with OPL2 and OPL3.
* Covox Speech Thing support. Uses YMF719 Microphone line.
* Secondary IDE port with PIO based access for stuff like CD-ROM drives.
* WaveBlaster header that can accomodate all the goodies.
* Fully functional GamePort with MIDI I/O and a polyfuse on the 5V line.
* Dedicated headphone output with a proper amplifier, can drive even 4 ohms.
* AC97 compatible front panel audio connector (lacks microphone support).
* Proper Line-Out with near 5Vpp output capability.
* Proper Line-In capable of 5Vpp signal input.
* PC-Speaker input. Repurposes Mono-In line of YMF719.
* Software controlled component and system resources management.
* YMFDEC, a custom CPLD that allows software control of various components.




If you are using SETYMF with some random YMF71x based card or you've found good use for some of the other utilities or maybe you just feel generous, please consider making a donation so I can continue working on more new hardware and/or software :)



Drivers and software

SETYMF utility for controlling the card in MS-DOS
Initialization Resources configuration Mixer and sound tests
This is the main thing needed for this card, all the power at your fingertips ! Be sure to read SETYMF.TXT for all the necessary info about features and usage. You can use this program with other YMF71x based sound cards also, albeit with some limitations.

Yamaha's Windows 95/98/98SE/ME driver package
This is the driver for whole Windown 9x family. It also includes a very decent softysynth that works only on Pentium and higher and a not so nice one that needs 386 or higher. If you plan to use it on a 486 you'll have to rename VSGM.486 to VSGM.VXD prior to the installation process (back up the original VSGM.VXD perhaps too). You will still need SETYMF to be ran prior to Windows to get full benefits that Yamaha's SETUPSA cannot provide.

Yamaha's Windows NT driver package
This is for NT line of Windows prior to Win2K which has built in WDM driver for YMF71x. I have not personally tested this but following README should get you going.
YOU WILL NOT GET FULL USE OF THE CARD UNDER NT BASED OS DUE TO INABILITY TO RUN SETYMF.EXE PRIOR TO LOADING WINDOWS !!!

Yamaha's Windows 3.x/WfW 3.x driver package
This is what you'll want to use with Win3.x and WfW 3.x, it only works in Enhanced mode. For real-mode you should use SETYMF and Windows' own Sound Blaster, Adlib and MPU-401 drivers.

Yamaha's OS/2 driver package
I have not personally tested it (I should sometime) but this is what you're supposed to use with OS/2. Follow the README and you should do fine.
It should be possible to run SETYMF.EXE under OS/2 as there's some level of DOS compatibility.

Updates and such

10.09.2018 * SETYMF has been updated to stop blocking IO used by YMF721 on my card on other YMF71x cards.
28.08.2018 * SETYMF has been updated to allow writing of custom PnP ID to a card.
* Two utilities for reading and writing PnP EEPROM have been made.
* Checksumming is not yet implemented so CTCx will still complain.
19.08.2018 * Seems that there are problems with CTCM/CTCU with the card. Apparently it finds checksums of 0 as errors while they're meant to show that checksum is a don't care, thus violating PnP spec a bit. I will look into adding checksumming to make things function with CTCM/CTCU.
12.08.2018 * SETYMF has a cosmetic problem fixed in it, the version was shown wrong inside the program. 0.4b is most recent !
* First report of a card in new home !
29.07.2018 * SETYMF has a small error fixed in it, YMFDEC wasn't updated properly when YMF721 settings got changed.
* Added a recording from DB60XG.
25.07.2018 * SETYMF is now much more friendly to random YMF71x cards.
24.07.2018 * I have finished building and testing all the prototype cards.
* I'm currently updating SETYMF to be more friendly to normal YMF71x cards.
23.07.2018 * Added more photos of the building process.
* Updated NT and OS/2 driver description texts.
* I finished cooking all the prototypes. After sleep there's lot of soldering ahead lol.
22.07.2018 * Most cards are laid and cooked, tomorrow goes into soldering connectors and whatnot.
* Updated Win9x driver installation instructions.
21.07.2018 * Added ROTT and Tyrian recordings.

Funstuff

Here are all the machines the card has been tested on with positive results :
* Portwell RUBY-9719VG2AR (C2D)
* Chaintech 6VIA5T-D100A (PIII-S)
* MSI MS-6368 ver 5 (PIII-S)
* Abit AB-BH6 (slot1) [had to set PnP OS Installed to YES or card didn't work properly]
* Intel SE440BX2 (slot1)
* Compaq Deskpro something (Slot1 celeron)
* QDI Titatium IB (Pentium MMX)
* Chaintech 5VLM0-D150 (Pentium MMX)
* Chaintech 5VGM1-C130 (Pentium)
* LuckyStar LS-P54CE Rev:G1 (Pentium)
* PCM-SC520 PC104 module (AMD 5x86 based) [requires SC520ISA to be ran before SETYMF]
* Intel Classic PCI/Expandable Desktop aka Ninja (486)
* SER 386AD-III (AMD386DX based board)
* 8517 Rev 2.1 (AMD386SX based board)
* Siemens PCD 2M (286)

Boards where the testing resulted in negative results :
* DCA Hippo VL+ (486) - the card basically resets after some random amount of time
* Abit AN4R2 (486) - the card basically resets after some random amount of time
* PCM-SX-33-8M-ST PC104 module (386SX based) - many IO locations seem not to work and card exhibits reset bug

I have become to call that the "reset bug". I have also noticed it on some other YMF71x based cards on those machines but not on others, I have not found any electrical difference between the cards and it seems when I transplant the chips from one card to another the problem doesn't move with the chip. I have done things like isolating bus signals and other things after setting up the card and yet I seem to be getting these "resets". Manifestation is that the mixer appears to reset to default state (very quiet with most inputs muted), IRQs seem to stop happening and whatever was last playing ends up looped on SB side or goes silent, games seem to go super slow too. IO assignments seem to stay intact and stuff like MIDI and Adlib music continue playing albeit very quietly. It seems to only happen on ISA/VLB based 486 machines, I haven't had it happen on 386 and 286 machines (Except the 386 based PC104 module). Also when ISA bus is behind a bridge like on all Pentiums and 486 machines with PCI slots there are no problems whatsoever so my only guess is that some bus cycle on the ISA bus will confuse the card or something. I have been unable to see any timing violations on oscilloscope on those machines compared to 386 and 286. Bus speed and amount of wait states seems not to play any role either.
So for the time being the card will not work properly on 486 hardware without PCI slots, I have not figured out why and whoever does will get a free card !

Here's a few photos and other bits about the building process for your (in)convenience :P
Mostly completed PCB design of this wonderful card ~
