the card I have is not branded, but it has "CMI8738 037D" chip on it - basically the chip looks exactly as the picture I am attaching (found that picture on Internet, it's not from my card, but the chip is the same). so, what I did on my test - set B) from my initial post to "1", i.e. set CMI8738 …

first (and maybe last, i.e. if we assume the datasheet is wrong) obstacle hit - it doesn't allow me to write to "PCI Configuration address 40H", at least on my CMI8738 revision 037D chip. so, anyone, any idea?

Let's Dig deeper: ok, a little more specific and technical information (for the more technically advanced users here). So, in the datasheets of other audio chipmakers of that time period, always the setting is called "DDMA base Address" (you can google for that and see datasheets for ALS300, Solo …

hi All, I am not sure from where to start this, but let's start from somewhere and without flooding you with too much information for the time being, but only with the essentials ... So, in CMI8738 datasheet "CMI8738_spec_v06_reg.doc" that is floating around Internet, there seems to be 2 very …

Pentium MMX 200 SL27J 5.4.3 - 2.5x, 3.0x just for the record with that one I can get it working on: 120Mhz, 150MHx, 180MHz and of course 200MHz. Pictures of the CPU and screenshots from SpeedSys are attached. On 120Mhz with cache disabled it goes does to 386DX 40Mhz. So, those are the modes - 4 …

So, I've just found out that Cobra generates noise not only when my electric heater is turned on and off by the digital thermostat, but even when I turn on and off the lights 2 rooms away - and yes I can hear that noise with my own ears when leave the doors of the rooms open - its volume is that …

So I'll have a CMI 8338 ISA, a FM801 PCI and a XG PCI card for my DOS SPDIF experiments soon. :) I guess you meant to type CMI 8330, otherwise my collection is exactly the same plus PCI CMI 8738, chip revision 37 - that revision is the only one that can mix OPL3 via the Digital Output. (It's off- …

the software, does it "recognize" the card as the version with SP/DIF, does it show the SP/DIF settings Yamaha Driver Control Panel Always provides the S/PDIF settings, no matter if it's soldered or not on the board - there is no check - the attached svreenshot is from unmodified card. Also, if …

SOLVED (thanks to a friend not on this forum who told me SPDIF connector model and corresponding Capacitor value from his noname Yamaha card) or How To Add S/PDIF Output on Cobra: A) S/PDIF Connector model is TX178S - that's Toshiba, hence "JAPAN" on the top of the connector. [EDIT] Oh, now this is …

the part is "AMP MICRO-EDGE SIMM CONNECTOR" - attaching PDF that contains table with all part numbers for it. so, you can search for "AMP 822058" or "AMP 822113", etc where those numbers are from the aforementioned table. Please, note some of the part numbers in the table correspond to 72-pin, not …

I have a variation of the same card in my retro machine (Aopen AW744) https://i.postimg.cc/59wDHpH9/20180525-155756.jpg Except that for SPDIF mine has the optical output onboard. I cannot send private messages (I guess disabled for new members), but please, could you tell us: 1) what is written on …

So, no one knows what are the values of the missing components like R58, etc? OK, I finally found some relevant information on the above question: A) the full-featured card (by that I mean the one that has the components for SPDIF Optical Output and SPDIF Optical/Coaxial Digital Input populated on …

@yawetaG: there is FM synth block inside most (if not even all) revisions of CMI8738, but there is not much research from the community and the information is very confusing and even contradictory. you can see the post from the great and real expert "nukeykt" that I quoted few posts ago: https:// …

Sorry, but i don't remember much about these drivers anymore. IIRC only modification i did for CMI driver itself was enabling FM_EN register bit by default. For OPL3 driver i've made various tweaks to mimic Windows 98 SB16 driver. Not sure i still have source code for it though. i recommend you try …

I've got the OPL3 synth working by modifying CMI8738 driver. I used this driver : http://code.google.com/p/cmediadrivers/ . The attachment archive is containing modified drivers(You must install this driver before),opl3 midi synth and other helpful tools. cmiopl.zip OPL3 MIDI synth based on WDK …

@all what are your thoughts on the following, as potential way to connect (digitally) YMF289B to EMU8000 (and respectively to its SPDIF output JP3) on CT3990 card: so, according to the information here: https://www.vogons.org/viewtopic.php?f=62&t=50071&start=60#p702925 on AWE32 with real OPL3, i.e. …
