SB 2.0 CT1350 capacitors

Greetings. I'm trying to assemble one of these cards from scratch, and I need some help with capacitors, especially electrolytic ones, since their values cannot be seen on photos. Only capacitance (in uF for bigger ones or code, like 104 or 331 for small ones) is needed.

Re: Newly made ISA CL-GD5434

I know a 4MB version has been written off (and perhaps not all that useful), but wouldn't it still be nice to leave a few solder pads to allow the end user to add 4MB if they want? It's not written off, just not in the first revision. If you can solder SOJ IC-s you'll be able to double-stack them. …

Re: Newly made ISA CL-GD5434

Ok, looks like I've routed everything. Now it's time to correct silkscreen, optimize and double-check everything else. And I've probably have lots of time for this - Utsource still can't send me IC's I've ordered. Few notes: 1) It's 2mb only for now. 1mb won't work due to schematic modifications …

Re: Newly made ISA CL-GD5434

Tiny update: I'm still working with basic PCB layout, progress is slow - I've got lot's of other work. If you want to help & have some knowledge in electronics I can send schematics so you can check it for obvious errors. Meanwhile I've discovered that VGA filter capacitors on my Matrox Millennium …

Re: Newly made ISA CL-GD5434

I am waiting for this to happen - 4mb is certainly not worth it , maybe keep it 2mb and sockets to upgrade to 4? higher resolutions and depth don't like iSA much but maybe some ISA 486DX2 could use them For 486DX2 any VLB VGA will be much better choice. SOJ40 sockets cost more than appropriate RAM, …

Re: Newly made ISA CL-GD5434

Perhaps you should use 4mb of memory with a gd543-4. Someone told that their ISA GD5424 was too slow to be of help to their 486. What type of machine would an ISA GD5434 actually accelerate? My target CPU is 386 or 486DLC. 4mb - probably as an option, but imo that's overkill - it's only needed for …

Re: Newly made ISA CL-GD5434

There is an example of a Trio64V graphics adapter for PCMCIA (NOT Cardbus), which is more or less ISA for laptops. It probably has a bridge chip to do this. A good GUI accelerator? Would a card like this work with a 286? Are there 286 compatible Windows drivers with support for the GD5434? Could …

Re: Newly made ISA CL-GD5434

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 …

Newly made ISA CL-GD5434

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. …

Re: AWE64 Gold CT4390 Firmware

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 …

Re: AWE64 Gold CT4390 Firmware

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 …

Re: AWE64 Gold CT4390 Firmware

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.
