I did not get a response so I opened a PayPal dispute selecting the “Item not as described” reason. The seller then contacted me asking if he could reimburse me 500 USD which I felt wasn’t enough and so I declined, telling him I’d accept $700 (shame on me). After providing PayPal with the details, …

Artex, do you want to post the photos and videos in the OP? I'll just toss in a few right now to ease the suspense. I must have sent 3 dozen during the repair. If you took photos of how the chip looked when you received it, that would be nice to see. I couldn't believe that the previous owner could …

Presumably, yes, especially on older 386 boards. The DRx2 does have the FLUSH circuit built in, which I believe is wired for such motherboards with a serial cache controller.

Personally, my favourites for pure 386 boards are the Chaintech 340SCD and the AMI Mark V Baby Screamer.

Not sure I follow your sentence grammar, but to rephrase, the motherboards which contain a 386/486 hybrid chipset tend to have built-in BIOS support and sometimes hardware support (the FLUSH circuit) for 386 CPUs which contain L1 cache, such as the DLC, SXL, SXL2, and DRx2. Even such, it is still …

Well, I also like 386-486 combination boards without VLB if there is no evidence of a 486 socket. You'd never know the chipset was an early 486 chipset. The benefit of these boards is that they often have built-in BIOS support for the DLC and SXL's L1 cache.

Seems like I've seen a few VLB-containing ALi-based boards which sport a PGA132 ("386 socket") and no PGA168 ("486 socket"). One had the solder pads for the 486 socket, while the other didn't. Even the solder pads would offend me. I am also interested in finding a VLB-386 system with no signs of a …

10 euro for a Diamond-branded S3 868 is, alone, a fabulous deal. Its always nice when the seller doesn't know what they have.

That sounds like a hearty exercise regime! So you are running a Tueleron at 14x on a socket 8 board? Impressive. It would be neat to see such a setup in a dual CPU platform. It would also be interesting to benchmark the Tueleron 933 against a more conventional Tueleron system. Is the system stable …

I'm not entirely sure if said individual is intentionally trolling, or if he is just particularly emotional and overly passionate, perhaps subconsciously, about wanting to 'be right' that it fogs any incoming information.

Not sure. Did the older versions of AutoCAD use the Weitek? I have never hunted down a Weitek FPU because of how specialised they are said to be. For collection purposes, it would be neat to have one though. I wonder if there is any hack to get the Weitek to work as a standard FPU, albiet, probably …

Are these programs freeware or shareware? If so, could you include them? I'm pretty sure I tested the motherboards with the AMD 386DX and the SIS and CHIPS were still quite a bit faster than the others in memory throughput, not just in speedsys, but also cachechk.

There are certainly deals to be had, but they are becomming harder and harder to scores for older rare hardware. A TI486SXL2-66/PGA132 sold for $20 on eBay recently. This occured because the seller didn't know what he had and just so happened that nobody else saw it, which is hard to believe because …

The thing here is only about the 2 cards, bcuz i have seen many people to talk that HD4670 is the fastest card, while it is not, and the HD3850 is the fastest AGP card, it was about that. I appreciate your sense commitment to the bottom line; I am the same way, especially with older systems. I am …

This post will be a bit of a brain dump upon reading this thread to-date. VLB slots on a 386 board only seem to be of performance benefit when using clock doubled CPUs. I recall there were some results in the 386 Speedsys post. If you are looking for a 386/486 hybrid board, most of them have the 486 …

Lots of drama in here; feels like modern politics. My line of thought is similar to Tetrium's. 92 fps vs. 61 fps, and 33 fps vs. 26 fps in a game wouldn't matter to me either way. I haven't heard the argument that synthetic benchmarks are more credible than actual game play though. I think a broader …
