Thanks. I like the idea of putting a separate SECC2 column to the center. More so than filling the space with Xeons. It is a pity there is no space for SECC 400 & 450 though :( Will need to source the SECC2 variants of 400 Mhz & 450 MHz PIIs which I currently don't have in my collection. Also not …

I decided to display my PII CPU collection on a wall. My better half picked a frame and place in our house where this project will be tolerated. So I have just and only 50cmx50cm of space which I would like to fill with Slot 1 stuff from my collection. I started putting together a layout. I thought …

Picked two early PCI high-end twin cards. (1) Spea V7 Mirage P64V Turbo with S3 868 and DRAM and (2) V7 Mercury P64V with S3 968 and VRAM always wanted to check what is the difference between VRAM and DRAM.

So I have some NOS 486 motherboards that only support 5v. So I have some 50mhz Intel 486 CPU’s But it would be nice if I could go faster at least 66mhz. Or 100mhz. What CPU alternatives are there available ? Can you list the best performance options ? We are hijacking the thread a bit IMHO. Perhaps …

got it cheap from a local seller with a free DX4 that was actually dead. I know about overdrives. I actually own a DX4ODPR75. The beauty of this is that it can convert a range of 3.3-3.45V CPUs, incl. potentially AMD DX4-120 or 5x86 P75 or DX2 variants with WB cache. The fastest dual-voltage AMD …

Bought this 5V -> 3.3V voltage adaptor. Finally I can install a DX4-100 in my favourite 5V-only 486 motherboard. The BIOS reports it as DX-50, but works fine. Filename DSC_7561.jpg File size 1.2 MiB Views 1095 views

I bought a nice looking Promise VLB EIDE controller for my 486 project. DSC_7545.jpg I installed it on to the motherboard, powered on and suddenly one of tantalum capacitors literally exploded. The capacitor sits between +12V line and GND on the ISA part of the card. The 12V line then continues to …

DX4 overdrive?

my precious is back :) it is not "new", but it died. i was very sad, it is very hard to find a late et4000w32p in this condition. i have send it to a friend, and he watched it under the microscope. the original soldering of the main chip was not perfect, they get off, and resolder again. it works …

Yes I did. Glad it is in a good hands. Did you get it working?

Finally traced down the ultimate ISA video card: Filename m64.jpg File size 1.83 MiB Views 2108 views Now that I have it I am thinking about where to use it. Probably an overkill for a 386 system. For 486/Pentium systems VLB/PCI cards are suited better... This is a misfit. 😕

Thanks. I've been googling this back and forth I found this :blush: https://www.vogons.org/viewtopic.php?f=25&t=55420 According to that post, which shows pretty much identical board, my board seems to be from Dell Optiplex 560/L. It is incredibly difficult to find anything about that computer. …

Yes. ATX is indeed a few years newer than this. I actually found this page: http://www.smps.us/power-connectors.html and it looks like it could be the same thing as "DELL PENTIUM II and III" connector mentioned on that page. At least the non-connected pin 19 is non-connected and I can measure …

I've always wanted to build an original P5 based 1993 Pentium system. I know it is not the most practical retro computer. But I want to have some fun with the FDIV bug and refresh some early 90's games. After some effort, I finally sourced a suitable board. I got it cheaply off eBay and it is new …
