I think this was the same board used in the powerflex. It was a pretty neat upgrade, but the 486 was kind of crippled without L2 cache, and 16-bit memory at 12MHz. I guess the one saving grace is that you still get the 486's onboard L1 cache.

Did ST ever get access to the MII? I only seem to remember them doing up to the 6x86L. I think they got dropped after Cyrix was bought by NatSemi.

If you have a lot of SIMMs to test, there are SIMM testers that can tell you. They're expensive though. Just read the datasheet. It's not that hard.

Ha, that's interesting. I could kind of understand why intel wouldn't want people to know about this, since they would lose money with buyers opting for a slower second CPU. But if that were the case, you'd think they try to disable this feature completely. So what's the deal with matching s-specs …

The TI and Cyrix 486SLC chips should be identical except for the branding. Unless they were manufactured after 1993, I wouldn't expect them to overclock very well. Unless your your chip is exceptional, 40MHz is probably the best you'll be able to pull off.

I used to be a diehard ATi guy. The Rage Pro and Rage IIC really turned me off of their products. I would say the Rage Pro marks the point where ATi stopped focusing on professional products and started catering to "gamers". My previous card was a Rage II+, which I really liked as a 2D card. I …

Nope. Because in the 90s I remember hearing stories of people blowing out the cache trying to overclock to 80MHz. SRx2 is not exactly cheap anymore, so I count myself lucky that 66MHz is even possible.

So you think the SLC 25/50 will have an upper limit of 55MHz just because that's all the TI version can do? I'm more optimistic about the Cyrix. It has far less cache, so it should be easier to overclock. With the Cyrix branded chips in particular, I would also think that the date of manufacturer …

I just looked into it. AMD had the 40MHz DX, but sadly no 50.

That has to be a misprint or something. The article clearly stated that the base 33MHz 386 was under $1000. What the hell is in that multimedia system that's worth nearly $2000? I'm pretty sure the multimedia kits weren't THAT expensive.

Weird. You usually only see HiNT used on those mini-EISA boards. This one was made really late too.

I always like the boards that have a socketted 386SX. Although it looks to be manufactured in late 1991, the sticker indicates it was sold in 1993, which is pretty darn late for a 386SX-20. This is also the first time I've seen the TI chipset used on a 386SX. It might be interesting to see if this …

I wouldn't be so sure about that crystal being needed. Isn't the chip in U9 a clockgen? It might be that this card can be sold with either a clockgen or an oscillator.

I've definitely seen the Cyrix DX-50. I always found it amusing that Cyrix ever bothered with these. The Intel version was never that popular outside of engineering and academia, and seeing as how the market for the DX-50 was already basically dead in 1993 it didn't make any sense to clone it. I …

I guess if you ever bought one of those ZEOS 386SX-20s with 0WS memory, you'd be pretty much screwed if you wanted to add more RAM. You could either get ripped off by the dealer, or you could buy regular 60ns stuff and add a WS, killing your performance.
