In my book, XP and Vista aren't "retro" yet. I do not really have much to backup how I define it, but I did notice XP running on the computers at the local hospital. I also noticed a few months ago that the local Canadian Tyre was still using XP point-of-sale. These examples by no means constitute …

elianda, it would be interesting to retake this video and not use the MPEG-1 decoder card, but keep all other hardware/software constant. I'm sure it will just show the video skipping around, but would really highlight the impact of the decoder card. I really like seeing these old systems run with …

Looks like this mod has made its way to eBay sales. www.ebay.com/itm/152517809130 The description is a bit sketchy though - superglued the heatsink, missing fan pin, and not confident in strength of solder job.

I too would like to know where to procure an inexpensive socket 4 motherboard so that I can add the results to the 686 benchmarks. I almost had a decent one for $30, but it slipped away. If you are looking for just the socket 4 P66 CPU, CPUShack on the CPUWorld forum had a few extra as of about 8 …

I found that even the not-so-expensive SRAM testers can save a lot of frustration with bad SRAM. All the SRAM I've found for DIP 28 and DIP 32 have been 5 V. Normally, you'd use two ordinary diodes in series to drop 5 V down to 3.3 V, not resistors. The diodes act as mini regulators in their own …

Seems like only about 1 in 5 fans I lubricate does any good. What do you recommend for double-slot aftermarket GPU cooling solutions? I might loosen my requirement after a bit of searching around.

I don't really play games, with the exception of running them to see how well they work. I might play it for 10 minutes, then wanting to do hardware again. For me, I want to optimise every board as much as I can, so a working PS/2 mouse is just one more item to check off the list. Also, I hate …

I can't name even my top 3... Although I have many different 486 boards I haven't really judged them. The one I like and use most is Gigabyte GA-486AM/S with fully upgraded cache to 1MB. Otherwise I also like 386/486 hybrid boards. Which revision do you have? This board is easy to add variable …

Found this older thread with Google and was surprised that there was not much information. https://www.vogons.org/viewtopic.php?f=5&t=40902 I have a few worn graphics cards with noisy fans which I was going to chisel off. Could anyone recommend a link for a decent and quiet aftermarket heatsink fan …

I feel that this thread is too google search catching. I still need some boards on my top list. Not many people chimed in here, so I suspect others …

This is the first 486 VRM interposer module I've seen which contains 4 rows of pins. The only other is the POD. Anyone remember what the 4th row of pins is for?

Have you considered buying an SRAM tester? Most units also include a flash programmer. These units are usually around $50-200. There are more expensive units which actually measure the response time from the SRAM, but the prices are ridiculous.

For PCI boards, I would think the Asus PVI-486SP3, the Biostar MB-8433UUD and Chaintech 486SPM should all be on the list. There are lots of good VLB boards. The Asus Asus VL/I-486SV2GX4, Aopen VI15G and possibly ECS Elitegroup UM4980. For EISA boards. I would say the AIR 486EI, Nice SuperEISA and …

Lookup the pinouts for the 486DX4 to see what those pins are for. They may be non-connect (NC). It is pretty neat to see a Dell branded VRM module. It was probably intended for a Dell motherboard, but may work in others as well. LT1587 is very common for use as a CPU voltage regulator. It has a low …
