Thanks! Turbo button works well on the fly, it decreases the speed to 33 MHz, so is on my AM386Dx40 area... I also want to connect the Turbo SW and Turbo Led to the display and the display to the board and to change the HI, LO to 66, 33 MHz for appropriate use of the Turbo feature and the display. I …

I'm aware of the ATX power supply and the converter! I can buy a 400w ATX PSU brand new with vintage look and dual socket (input. output) on the back, but I must use Sata to Molex power adaptor and Sata to FDD to add power connections for my devices.. It's a good solution... Fortunately all my AT …

Thank you for your answers... I made it to work by increasing the length of the power switch plastic rod using a piece of drinking straw. Now it aligns to the hole of the button. 😀

I build recently an i486Dx2 66 MHz (always wanted it back on 1993 - 1995) VLB machine and used an old desktop case (with LED Mhz display, turbo, reset button and keylock) which needed some refurbishment. The plastics were on terrible yellowish state so firstly I made a retrobright effort without big …

Today arrived my first ever VLB VGA card, but my VLB full system didn't arrived yet to test it. So, I have a question, the card has 8 chips of GM71C4256A-70 DRAM installed. This means that the full amount of RAM is 2MB?

AM486DX4 120 MHz That is a sweet CPU, and a somewhat rare one. Most people settle with a 100 and clock it to 120. I have one real 120 in my collection. Yes I know that! Just bought it two years ago along with the motherboard, RAM and an S3 Trio64 PCI for only 50.00 €! I was thinking it to downclock …

Very good motherboard for 486Dx4+ machines. I think that they are more stable than the VLB 486 motherboards. I have one with the ALi m1489/m1487 chipset (I didn't noticed that it's slower than other chipsets of its era) and a AM486DX4 120 MHz and 32MB RAM installed, S3 Virge Dx 4 MB PCI with Windows …
