Re: Voodoo 1 vs. Voodoo 2 on a 486

Multitexturing happens on the Voodoo card, it doesn't matter for the CPU or the bus. The Voodoo 1 needs 2 passes for multitexturing, while the Voodoo 2 only needs one pass. While, in theory, you could get more frames in games that use multitexturing, in reality it won't happen since a slow CPU …

Re: Resurrecting an old IBM Valuepoint 486 machine. How can I get it to contribute to World Community Grid?

I probed the VRM connector using a multimeter and I think I know how it's wired up. The connector has 20 pins total. The 10 pins towards the front of the computer are the input pins. The 10 pins aft are the output pins. The little jumper block that's installed just connects the input and output pins …

Do you know the exact value point model you have or a part number of the motherboard or VRM? That block does suggest it can support 3.3 but quick google I'm finding machines the 5v support only so not sure how it works either. Not sure of the motherboard model, but its a Valuepoint 466DX2/Dp. Best …

Re: Resurrecting an old IBM Valuepoint 486 machine. How can I get it to contribute to World Community Grid?

I used to run SETI@Home on my Pentium 3 back in 99. I remember Intel had a build with SSE support but it wasn't allowed because SSE is single precision. I wonder if a P3 could complete a unit in a useful manner these days. I can't remember if there were any 5v chips at 100MHz..... Certainly there …

Re: Resurrecting an old IBM Valuepoint 486 machine. How can I get it to contribute to World Community Grid?

Here's the machine I am working with, looks like an Opti 82C802G chipset. Need you guys' help though! The installed chip is apparently a 486DX4-100 (per the sticker on the side). Now, this machine came with a DX2-66, so I know it originally was set up for 5V operation. I am concerned I will fry this …

Re: Resurrecting an old IBM Valuepoint 486 machine. How can I get it to contribute to World Community Grid?

Well, thanks for the tips so far. I'm just waiting on a PS/2 keyboard to get started. Even in the likely event WCG fails, I'll be able to relive the glory days of DOS games like Whiplash - I think there's even a 3dFX version that can use the Voodoo card. (If you haven't played Whiplash, you haven't …

The minimum RAM requirements are 200MB according to https://www.worldcommunitygrid.org/help/viewTopic.do?shortName=minimumreq Additionally, I would not be surprised if the x86 client application requires instructions that your 5x86 does not have . Other than the "can it be done?" factor, is there a …

Resurrecting an old IBM Valuepoint 486 machine. How can I get it to contribute to World Community Grid?

Not sure if this is possible, but my goal is to get this machine to complete a task from World Community Grid (a distributing computing project, think SETI@Home). Each task is single threaded (A modern chip like the Ryzen will run a bunch of them in parallel). But the tasks are good for a week …
