I know what you mean. This is how i have it btw - minimally intrusive to the PCB - also very accessible.

Interesting topic. I run here 1.06 D03 with ics 9250cf-08 and dual 1000/256/133 slot 1 cpus. Two mods are applied to the board - one for higher ram voltage and another for additional fsb/pci frequency options. I have it completely stable at: - 140mhz FSB and 33.44mhz PCI with 3x256mb ram, it takes …

Alaris Cougar II, based on OPTi Premium 82C499 B chipset. Comes with soldered on-board IBM 486BL3 (blue lighting) processor, 486 Socket 2 (Intel Overdrive ready), Appian ADI/2 EIDE controller (Adaptec AVA-2625VL). An interesting and rare piece of retro hardware. Both boards are really well preserved …

Thanks Hezus. Btw i actually do not collect retro hardware. Hoarding is not my thing. I am more into building handful, but really good (to my liking at least), fully functional retro PCs. As for this "blog" here - out of interest i acquire specific items - things that i could only dream about back …

A while ago @ekb mentioned to me that the 286 VLSI system from page 1 may not be long-term stable, despite my initial claim for complete stability. He has the same board and was having hard time stabilizing it to survive 10 or more rounds of CheckIt3 memory test. I tried that here and yes - got …
Re: Can anyone confirm i'm buying the correct PC-133?
Posted on 2020-10-13, 23:42
I somehow always had bad experience with Micron memory - from the early SIPP/SIMM days all the way till always :) The best PC133 memory modules i encountered so far are based on Mosel Vitelic and NEC chips (specific models, of course). At least these are the ones that tick stably at 140MHz+ FSB with …

386 motherboard JUKO 386DX W/B based on OPTi 495SX. An interesting and great looking piece of hardware from year 1993. Board/chipset is very versatile. Offers both clock generator and crystal oscillator circuitry. Covers wide range of CPUs - from 386DX to 486DX#. Minimum supported frequency is 33MHz …

Thanks for the link. I remember reading it before. Spent some time this morning to try the SXL CPU on few 386 boards according to your notes in that link - DTK (Symphony), ASUS (SIS rabbit), FX-3000 (UMC) boards. Things didn't work out with the ASUS board. The Symphony board takes the processor to …

I didnt know that there is 66mhz 387 fpu 😀 I used the next flags: cyrix.exe -e -r -i1 -i2 But i know that i didn't spend enough time on it, so there is ground to be covered for sure. Do you have a good formula about the flags ? It felt that it is a case by case thing. Thanks.

Yes, sxl2 can tick with 55mhz, but without FPU and RAM reduced to 4mb. These limitations combined with the overall instability of the system exceed my tolerance threshold 😁 Still, it is interesting to see how far we can roll with 386 class hardware.

The initial post suggest that the clock generators were swapped, but ics9150 is pin incompatible with 9250. Or do I read it wrong ?

@The Serpent Ride Agreed. Hi kixs, My retro interests are mostly within the 1990-1996 time period and around 2/3/4 x86 hardware. Some of my findings: https://www.petershipkov.com/temp/retro_pc_im … rks/vlb_pci.png it is from this post: Re: 3 (+3 more) retro battle stations

Great information. Thanks for taking the time to put it together. Here is my thinking about S3 968 and 486. On a 486 class machine, considering a decent video card, when it comes down to non-accelerated DOS graphics - performance is hard CPU bound. As a result we are largely stuck in VGA modes. The …
Re: Diamond Stealth 64 Video VRAM VLB - Memory upgrade
Posted on 2020-08-24, 05:03
You have a point. Let me rephrase - s3 968 seems to 10% to 30% slower in DOS than many common video cards from that time period. Still, pretty ok in most cases for 486dx# class machine. Better ? 😁

The pci version is pretty good in windows (still quite slower than the mga), but is dismal in dos. Or at least thats what I see here. Is the view different from your tower ?
