ATI Graphics Xpression (Mach64 DRAM). Need to find a donor card with 4bit DRAM chips to fil the bus before testing.

More TIGA stuff. I think it is Spea HiLite. 2 MB VRAM + 1 MB DRAM.

Thought that, too, in the first place. But after looking up some datasheets it looks more like AHOLD which is kind of necessary for function afaik. No, that is A27, so an address line. Nothing will work without this pin. Looks like AHOLD to me too actualy (given we are looking from pin side of the …
Re: VLB video card memory

Yes no benefits. 2nd MB would only enable support of 1024x768 with 64k colours instead of 256 and 1280x1024 with 16 colours. However, both with unusable interlaced refresh rates (due to slow RAMDAC) which look ugly on CRT and rarely work with LCD screens. So there is no point. Often memory sockets …
Re: Dell Dimension 486SX 25 processor swap to 486DX. How do I change the bus speed?

The 4 pins on lower right side of the clock generator specify CPU frequency (multiplied by 2). Filename Screenshot 2023-01-11 at 13.30.58.png File size 214.39 KiB Views 319 views So my guess that they are either wired through some jumpers or hardcoded. Should be easy to find it out.
Re: ECS Local Bus VGA card artifacting
Posted on 2023-01-06, 11:32
Hard to tell. I'd assume it must be something in the RAM interface rather that analogue path or clock, given it forms some sort of regular pattern. I suppose you tried to remove all socketed chips from sockets, clean connector, run it with half of RAM to simplify the problem. Perhaps you could use a …
Re: S3 86C805-P Which vendor?
Posted on 2023-01-05, 11:05
In general it is better to use vendor driver. That FCC id lead to obscure company "Full Yes Industrial Corp" - https://fcc.report/FCC-ID/KC7-S3805/ Many branded card drivers will refuse to install without having original BIOS. You should be able to use generic "S3 Flat Model Windows Driver" which …

I was finally able to play with this board. It has a ton of settings in BIOS some of which are uncommon and not obvious if they improve performance or not. Found it faster with L2 cache in flow-through than pipeline mode (there is a jumper next to the CPU). With some tuning I was able almost to …
Re: Open case high-end 486 VL Bus reference system
Posted on 2022-12-17, 16:10
That may be true but it's still interesting to see the numbers. More data the better and your setup may squeeze an extra fps or % in a test and become the ultimate VLB board. or maybe not, from what I've read VLB/PCI combo boards are usually a bit of a compromise but it does give you an even …
Re: Open case high-end 486 VL Bus reference system

Yes. I've seen WJG6260's tests. I think performance of VL-Bus cards in DOS PCB/3DB/Doom/etc. is now quite well undestood (and frankly nothing to write home about). Basically ARK1000 slighly faster in DOS than anything else with late S3 and Tseng chips following and Cirrus Logic/Trident/ATI all in …
Open case high-end 486 VL Bus reference system
Posted on 2022-12-17, 00:18
Over the years I accumulated quite a few of different vintage VL-Bus graphics cards. I started benchmarking them on my Vl-Bus NexGen 586 system . I thought it was a good idea as NexGen system is a 5th generation platform which should perform favourably against 486 removing many bottlenecks. …

Thanks for the manual. I also happen to own one mb with ALD chipset and PB cache. https://dependency-injection.com/wp-content/uploads/2022/04/DSC_1558-1.jpeg Will wait for your findings, but II found it actually slower than other 486 PCI motherboards I own (such as PC Chips 919 or MSI4144). IMHO …

I might add something with them. But, most likely will trace down a SB 1.0 to have a period-correct representation of CMS.

I can't believe it took me 2 years to finish this project. But I finally completed my Sound Blaster display unit installation. I ended up picking these models: CT1320C - Sound Blaster 1.5 (simply because I don't own CT1310/CT1320A) so it represents the very first SB models CT1350 - Sound Blaster 2.0 …

Re: 486 dx4-100 outperforms P100
Posted on 2022-10-23, 21:01
Yes. There is nothing wrong. Many simpler benchmarks and games like Doom run faster on a tuned late 486. The Pentium architecture with superscalar execution units, branch prediction, deeper pipelines, split-cache architecture, etc.needs certain complexity of software to show it muscles. P100 is …
