clb , this "CTR Terminator" project seems interesting, but why you're planning only ISA version of the add-in card? For example I have no ISA videocards (currently I own one VC512TM Trident TVGA9000i-1 and one OAK OTI-067) with so called "feature connector", but I found this 26pin connector on my …

Here it is - sharing results from my attempt to make DIY pass-through cable for Voodo 1/2 card. I used about 0.5 m "Category 5" network cable (this build needs five twisted pairs wires, so two pieces of about 20-25 cm of Cat 5 cable), a couple of telephone wires, aluminium foil shielding from the …

Driver optimizations for non-actual videocards may be obliterated even if this newer version driver still supports older generations videocards. Тhis may be done deliberately and …

It depends, physics still apply. A good low ESR capacitor for higher ripple current 3300µF 16 V still measures 16mm x 22mm: https://www.digikey.com/en/products/detail/rubycon/16ZLJ3300M16X20/3564416?s=N4IgTCBcDaIIwDYBaAZAUgZgwBmwWUQA0xsQBdAXyA I doubt the original 1500µF 6.3V were that large... …

if the capacitors are in parallel then you can replace two 1500 with one 3300 True, the caps are in parallel but I'd like not to change the mobo appearance. What "appearance"? Even the manufacturers like Gigabyte used this "trick" to spare some parts from their motherboards 20 years ago. I have one …

Do all CRTs harm your eyes? Isn't it related to refresh rate? Yep, my eyes have always been overly sensitive to the flickering from CRT monitors and cheap LCD displays with backlight PWM-regulation. Definitely I don't think that ever again I'll need even a quality CRT "crate" (like some of those …

This is Palit Daytona nVidia GeForce4 MX440-8X 64MB DDR 128bit. I have exactly the same videocard and it is declared as with 128bit memory bus, but better off check with GPU-Z. The DDR chips on my card are PMI HP58C2128164SAT-6 and I can't find datasheet for them.

Oh yeah, forgot about the tabs I put on the interposer. That would work for sure. You could quite easily just stack the PCB, the socket and the interstitial socket, and just use it like that without any soldering as a heatsink retention clip.

You laugh, but it was quite common back in the 486/Pentium era for the heatsink to be attached with thermal tape to the CPU. I know that, but these CPUs are with factory glued heatsinks. But for the sake of a mobo with a crippled socket to cripple a processor... no thanks! Of course, this is my …
