Really? Virge DX is twice as fast as Rage II+ in DOS? I'm surprised that fact wasn't more prominent back in 1996/97. I seem to recall both the Virge series and the Rage II cards getting good reviews in PC Magazine. The thing about the Virge cards is that the memory clock and the core clock can vary …

I always assumed that the "87DLC" FPUs were just rebrands of the 387 FPUs, but who really knows. What we do know is that they perform pretty much the same, but it's possible there are bug and compatibility fixes. Unless we find some company memos or contact a former employee we'll likely never know …

TI 486DLC chips also seem to be far more common the Cyrix branded type. I don't know that ET4000 is really much better than a VGAWonder (if it's a plus, XL or XL24). On an ISA bus, most of the later cards seemed equally slow to me. Even if the Tseng is slightly faster, the VGA Wonder can store …

Count your blessings we have access to any 386 BIOS images at all, mostly thanks to two Russian guys. Trying to find 386 BIOS images in the 90s was like an exercise in futility. Forget about MR-BIOS. Be lucky if you find anything at all. There are only a handful of MR-BIOS images available. …

The chipset on the original motherboard is from "Solutions". It is not partially a UMC chipset. That extra chip with the UMC logo is the 85C206 system chip, which is a clone of the one from Chips and Technologies. No matter which brand of 85C206 you have they are all functionally identical and can …

Hmm...I'm really interested in DOS benchmarks for your Trio32 VLB. I wonder what kind of meaningful tests could be done. I'd especially like to compare against a Trio64.

In my opinion, finding a good S3 868 or Trio64 based VLB card will be almost as impossible as finding a good 4MB card. Might depend on the location though. Europe seemed to get more of the 868 based cards. The Trio64 used to be super common for VLB but I hardly see them anymore.

That looks like an Intel board. There are others based on this chipset, but many are OEM.

You don't need to do anything else to slow down the 386 CPU, but you will need to make adjustments to memory timings and clock dividers in the BIOS to make sure other devices on the motherboard aren't underperforming.

It's interesting, and I'd like to know the reason why your boards don't have a 66MHz bus setting. Maybe the yields on Neptune were low at 66MHz and Intel sold off the rejects for use at 50/60MHz only? The Neptune was obviously designed with 66MHz in mind, and it was pretty clear that the Pentium …

I own a Neptune, but that only supports P75 and P90. I'm pretty sure if it supported the P90, it should also support the P100 as those two chips were released at the same time. The P75 came out a bit later. Perhaps your board doesn't like 66MHz bus speeds? Anyway, I am quite certain that at least …

I'm also really interested in building a P100 or p133 system, but I feel it needs to have a motherboard that was available when the P133 represented the fastest available option from Intel. Probably either the Neptune or a 430FX. I'm probably going to go with a dual Neptune.

I doubt that any PCI card on a 486 can even get close to 133MB/sec. I would guess more like 20MB/sec at best.

A few people have already done this. The best upgrade for your card is something like a make it 486, which would upgrade your 8MHz 286 to a 16MHz 486SLC (clock doubled).

One of the most interesting of the NEC V series is the V33A. It can address up to 16MB like a 286. Unfortunately, I don't know that it was ever used in a PC. It's not a 286 clone, and I don't think it has a protected mode. BTW, according to that wiki page, the Vadem VG330 (a portable?) has a V30MX …

Maybe when equipped with a 15MHz CPU, the bus was decoupled. Are there any specific settings for the 15MHz version in the Juko ST manual?
