CL-GD5434 stocks are high and prices are low (7$), so there is no need to salvage it from PCI cards. Most expensive parts at this moment are PCB (since it's gonna be 4-layer) and 2mb of FPM DRAM (might be cheaper if it'll work with EDO). As for Trio64-based ISA card - I'm pretty sure that's …

Is there anyone interested in newly made ISA CL-GD5434 card (similar to STB Nitro 64 or Diamond Speedstar 64)? Performance-wise it won't be faster than Tseng ET4000, Trident 8900D or AVGA2, since they are all bottlenecked by ISA bus, but still it will be a high-end ISA VGA with GUI acceleration. …

I'd vote only for one additional feature - S/PDIF TTL header (like on creative cards) or an optical out instead of RCA jack. And a DIY kit - complete or board with main components only.

Is there any reference in datasheets or other tech docs for the capacitor on SN76489 pin 7 to 9? SN76946 datasheet only recommends 10R & 0.1uF RC from output to ground.

Finally I've completed my Snark Barker, with "line" out wired before the volume pot. It sounds better with less noise, and the volume level is ok. Looks bit messy though. The SAA1099 chips are pretty hot - is this normal?

Edit: to answer Jager's question, the config EEPROM contents in the Dell utility starts at offset 6436 and ends at offset 6599. If the utility (somehow) can be properly expanded to fit the entire 512 bytes, then the CT3670 and CT3990 config data can fit there at least. I have necessary eeprom …

Looking at the exe I've attached I think that the actual firmware is right at the beginning of the file. Maybe it can be altered? Also it is also possible to program 93c46/66 eeprom via LPT port, but you need soldering skills. (in russian http://www.sblive.narod.ru/UpToRealLive/UpToRealLive.htm) So …

That's the only software I'm aware of. It's from DELL website, extracted from AWEFlsh.exe, and it updates on-board eeprom, making any AWE card into, presumably, CT4502. Edit: There is also sb2awe, capable of writing anything into boards eeprom, but it's pretty hard to find.

From board manual: "DIM1 and DIM2 only support 3.3V (unbuffered) EDO and SDRAM modules." Not sure how this supposed to work, since there is no voltage converter near RAM slots and I measured 5V over empty slot. Probably SDRAM should be 5V-tolerant, I've read about such modules, but mine are 3.3V- …

Just a thought - tapping to the volume pot bypassing the TEA2025 should give a less noisy line-level output, am I wrong?

https://gona.mactar.hu/DOS_TESTS/ S3 should be good, matrox is pretty bad in DOS

V30 For 3.25' drives just use a generic Winbond or similar multi i/o card with floppy drive support and fit 1.44drive. It will boot as 720k but using a small tsr called 2M you can access a 1.44meg disk. That's also plan "B", I'll try to use only 8-bit cards in my V30. And, to my knowledge, 1.44M 8- …

Or should I call this none-on-one, since it's several kits intended for a single test bench rig and none of them are 100% complete? :blah: 10 years ago or so I've collected some old hardware, and now I'm testing if it actually works. And, indeed, most of it works perfectly, with one pretty sad …

the datapath is usable as a display - later, when I finish with the good usability of my tool - i want to focus to minimize the input lag. They are quite similar hardware-wise, so I think lowest possible input lag might be close enough. Meanwhile I've got an answer from a tech support regarding …

Foresight Imaging Accustream Express 170 Got this board relatively cheap (less than 100 USD). On paper this looks like a perfect solution - it can capture nearly everything - DVI, HDMI, VGA (RGB & YpBpR) up to 1080p60, PCI-e, Win10 drivers, pass-through. More recent versions of this board have …

Refund is an obvious way to go, but if you'll end up keeping them you can try to fix them by cleaning the contact pads underneath the board. Unscrew the PCB (only PCB!) and gently clean the pads that touches the drive head contacts using alcohol and soft pencil eraser. Then use erase and scan …

Started sorting and repairing my old HDDs. Note for Quantum Fireball users (EX in my case) - Panasonic AN8428GAK motor comb IC can overheat. This leads to drive stalling and randomly parking. With a small radiator, some airflow and complete mhdd erase I ended up with a fully operational drive (only …

Greetings. Can you please share ROMs contents of this board? Mine is basically the same (minus half 44256 slots), but with a strange BIOS (same sticker, but with v1.07 written by hand). Both halves that should be even/odd are almost identical, and I think that's why my board appears to be dead (no …
