Re: Can anyone share HD images of Diamond Monster Fusion PCI?
Posted on 2021-02-05, 12:10
Hi. Can you read value of the r81? It's on the back side, to the right of the main IC, near c150. upd: nevermind, its 85X = 75 Ohm 1%.

Unbelievably, I obtained the SAME TYPE OF BOARD AGAIN (Hi/Lo, ver 2.01), in a complete computer, with a bootable hard disk and high density floppies, which both work. I'll be dumping the ROM at some point. PM me if interested ;) Thanks, but I already obtained one from Anonymous Coward. I even …

Searching for ET6100 BIOS
Posted on 2021-01-12, 11:52
Greetings. Recently I've found that ET6100 ICs are pretty cheap in china, so I've decided to upgrade one of my "out-of-trash & requires repairs" ET6000 boards with this chip. However I cannot find BIOS for ET6100 online. Can anyone dump it, preferably using a programmer?
Re: Any noticeable difference between the different Aureal Vortex 2 cards?

Aureal Vortex II AU8830 rev. A2 and B0 benchmarks B0 uses less CPU than A2. Some say MX300 has better analog path.
Re: ITI-714 Tseng ET4000W32i + VIPeR Fx
Posted on 2020-12-15, 06:12
Received it, at least it works as a regular ET4000w32i in DOS. Had to wire VGA jack to the lower right header & 0ws "jumper" directly from ISA to the main IC. Still no luck finding software & information about this card.
Re: VRAM options (Virge)
Posted on 2020-11-27, 17:57
You need to use EDO in Virge. IC41C16256, M11B416256, AS4C256K16E0 - these should be fast & cheap.
ITI-714 Tseng ET4000W32i + VIPeR Fx
Posted on 2020-11-17, 10:33
Greetings. I see this board (full name - Insync Technologies Inc ITI 714) for sale on a local auction. It's badly damaged (VGA is ripped off with part of the PCB), but it may be OK. Can't find any drivers and info, other than it's probably a ET4000 ISA card with S-video & composite capture via …
Re: Sound Blaster 1.x vs 2.0 -5V Requirement
Posted on 2020-11-09, 20:23
SB 1.x uses zener diodes to create filtered 5V for op-amps. On SB 2.0 op-amps are powered directly from 5V rails. Both sound ok though, maybe i'll try measuring their noise someday (i've got both snark barker and newly made sb 2.0).
Re: Can someone please identify this Graphics Card?

This GPU has native AGP & DVI, so it's FX-series, 5600 or 5700.
Re: HardMPU, anyone?
Posted on 2020-11-01, 07:31
Greetings. I've encountered a small problem with HardMPU - some of the boards I've made only work after a soft-reset. Otherwise it is not detected by configuration and games + no HardMPU line on MT-32 screen. As far as I understood that depends on the host system and board itself - currently I've …
Need help restoring AWE32
Posted on 2020-10-14, 09:54
Greetings. Long time ago someone donated me an AWE32 CT3990, probably already with problems. By the time I was able to test it only SB16 part of it worked, EMU8000 test ending in total system hang-up. Since EMU8000 chip was heating up I assumed that it was faulty, and bought a scrapped CT3910 - also …

Do you have any assembled kits available? I'm okay with a soldering iron, but I don't trust my hands with that level of micro-soldering yet. Sorry, but first batch is sold out, only 2 empty PCBs left. I'm thinking about ordering more parts/PCBs, maybe even partially machine pre-assembled, but I'm a …
Re: An idea about making MIDI daughterboards from existing sound cards
Posted on 2020-09-27, 20:22
Some thoughts after datasheet digging - ES690 won't work without ES1xxx, ES692 datasheet even has daughterboard schematics, but I can't find replacement for TDA1311 - its a pretty crappy DAC.
Re: An idea about making MIDI daughterboards from existing sound cards
Posted on 2020-09-26, 10:28
I see several ways here: 1) Just install one of these cards alongside with your main one, disable as much features as possible, leaving only MPU401. On some cards I think it is possible to disable it as well, feeding MIDI to gameport or wavetable. 2) Some cards may work without ISA slot, with some …
Re: Newly made ISA CL-GD5434

Ok, that didn't go as planned. These are captured images from my 5434 and Trident 9000b. Long story short - when trying to display 320x200 image (WinBios or 3dBench) with 720x400 or 720x350 resolution both look horrible. Lowering horizontal resolution to 640 pixels results in great image for both, …

Using an LCD monitor as a reference for output quality is a poor choice. Using an OSSC to capture over the VGA input (with appropriate 400p sampling mode selected) would be preferred I don't have an OSSC, but I do have a DVI/VGA capture card. It's currently unplugged, but I can try. I'm expecting …

I found a couple of GD5434 PCI cards in my stash and made BIOS dumps for you: Thanks for 1.24b BIOS, I'll check it later - the latest one I've got is 1.22. Count me in ! How much will be unpopulated PCB alone ? I need something that won't generate vertical stripes on LCD (in 320x200) - my Trident …

Ok, finally I've assembled one. And, surprise, it works! Few notes: 1) Performance on UMC 486SX is the same as AVGA2 - as I expected. (Note - my AVGA2 runs at maximum possible MCLK & agressive timings, i.e. as fast as it can) 2) I've tested it with Diamond Speedstar 64 & generic PCI BIOS (still …
