The stuff you guys find in dumpsters are the stuff of envy.. Makes me wonder which dumpsters I should check out for these kinds of hauls. Surely not residential dumpsters?

Got around to finally replacing a barrel battery on my 486 system with a NiMh cordless phone battery 😁

If you haven't already, go here: http://www.falconfly.de/voodoo2.htm Looks like some (3-4) of the 'legs' of on the corner of one of the 3dfx chips has been severed. So that's likely why. Going to see if I can attempt a repair. If not, I will just eBay it. Share a photo of the damage? Unless traces …

Well, no, I have not really tested the EXT BAT headers for current - should I do this with the power plugged in and the board powered? I think it's much easier to just solder headers onto the old battery connectors. I'll do that :) Aaaand, done: http://image.bolterandchainsword.com/uploads/gallery/ …

Fitted my Voodoo 3 with a spare 60mm fan (actually did this a while ago..) http://image.bolterandchainsword.com/uploads/gallery/album_11505/med_gallery_60983_11505_528203.jpg And fitted my GF4 Ti 4200 with a 40mm fan (this one came with a big ass case fan bolted on it and a Ti 4400 firmware flashed …

Ok, so I clipped off the barrel battery and have the replacement battery fitted with an extension (made using header pins and dupont jumper wires, and some electric tape) so that it can be glued to the case bottom. All is well. Except the question of how to charge this thing? http://image. …

Aren't 1055T's still more than most computer users need? IMO those are still high-entry level CPUs even for gaming. 6 Thuban Cores at 2.8GHZ. I'd tend to agree with the Thuban 6x being quite adequate for even modern rigs. Actually, my Phenom II 3.2GHz (4x core) is still enough for most of my gaming …

I would say the Elan Vital T10 screams PII era to me. I have P166MMX in it but I am considering moving a PIII450 into it.

Spent all my free time at work trying to figure out my build plans.. What's throwing a spanner in the plans is that I have no Voodoo 1. What I currently have: P166MMX, 64MB, Matrox Mystique 220, Voodoo 2 (GPU too fast but can do Quake respectably, probably main PC for retrogaming) PIII-450, 256 MB, …

How about phone battery packs like these? They look very suitable for fixing to the case and connecting to the external header:

Couldn't find NiCd rechargables available fast, so settled for NiMh rechargable AAAs, thanks.

FWIW, using AAA NiCds would match the voltage of the original cell. It would be especially good if the external header supports charging. Would using non rechargable alkaline AAA batteries cause issues if the ext battery header supports recharging? Should I use rechargeable AAA just to be safe? …

The battery currently on the board is a GP60BNKx3 NiCd so I'm guessing it's rechargable, I'll remove it by chopping its legs off and find something suitable and rechargable to connect via the ext battery header, probably a 18650 3.7V rechargable and its holder fixed onto a suitable part of the case …

This is a copy paste from member appiah4's other thread touchng the same topic. Notice that the pin number order is as it was shown in the picture in the other thread, to get it right you need to rotate the picture in this thread 90 degrees to the right. This is one of the reasons I really dislike …

The battery header is both a battery header for an external battery and where you clear the BIOS settngs. The jumper closes the circuit and connects the onboard battery to the BIOS chip. If you remove the jumper you dsconnect the onboard battery and clear the BIOS settings. Do not move the jumper …

Thanks; I was hoping the 4 pin below the battery was an External Battery connector but I guess it's not.. Never saw a 4 pin CMOS clear jumper before. I could try experimenting with the upper right FSB jumpers.. How safe would it be to run this board at 40MHz? I've seen U5SX 486-33 and U5SX 486-33F/ …
