One extra surprise: Boards with this chipset tend to come with a proprietary COAST-like cache module with async cache. This one does too but with a little surprise:

love that, can you post photos of the module outside the board? Is it fully reusing COAST slot or is it something weirder?

Something like this?

Edit: those chip codes on the back aren't legible, this should be better:

It's not reusing coast, I think it pre-dates COAST on the PC, see the 1994 date - COAST was used in Mac before then but wasn't used on PC until 1995 and i430FX. Also see the width, 105mm at the connector, where COAST was min 110mm.

A bit concerned about the "P54C 3.3V" bit - makes me suspect I can't use this module if I have a P5 5V installed...

I was about to mention just that ... I'm afraid you can't 😔

Couple 486 boards.

SPRING CIRCLE SS486 REV. P2C

ASUS ISA-486SV2 (rev 3.10)

VLB board will probably be more fun to play with, but I uhhh, forgot about the whole "no onboard I/O" thing. 😅 Have to put that one aside until I can acquire an ISA or VLB IDE card.

If you wanna go somewhat fast on the VLB board you might have to pull half the cache, some slugs in it.

OMG is that MR BIOS the one that came with the board? If so, please dump the contents! As far as I know no one has been able to find MR BIOS for 486 SiS chipsets!!

EDIT: look like someone else has the same board and dumped the BIOS already in this post.

..who does that, matching 25ns cache with 20ns cache.

Grabbed a "blue" Intel 486 SX759 Overdrive today for my 486 VLB build. Never seen a blue one before. Not sure how rare they are but I love the color.

Well, it's not that common with this original blue Intel heatsink, at least. I've seen them for sale only once or twice in the last years.
Besides that it's really just a regular 486DX2-66 (but a nice one 😀).

Added a few CPUs to my collection, a rare 2Ghz 423 Willamette, and two AMD 486 CPUs, a DX2-66 and a DX5-133 both have 16Kb Write Back L1 cache so should be quite fast in their respective classes. The 2Ghz 423 is one of my WANT to haves as now I own both the slowest and fastest 423 cpus, itll be fun to see just how much better the 2Ghz is over the lowly 1.3Ghz on the same hardware.

I'd be reading that comparison for sure! 😀

The 2GHz Willamette s423 is almost unobtanium, price-vise; I'd want one as well, but not ready to pay those prices they are going for at the moment.

yeah, Grabbed this one at 100 USD which isnt the craziest price I have paid for a rare CPU, normally see these going for 150 odd sometimes higher.

Wow, I didn't know they would've gone up that much price-wise.
I bought one about three years ago for 5,60 EUR incl. shipping in the bay. Like all slower ones I have which all stayed below 7 EUR.

The 2Ghz models dont seem to show up on evilbay much and when they do they are either auction only, silly expensive BIN and normally dont post outside the US. I got lucky with this one only being 100 USD BIN with international postage.

I was wondering that though, because V3s seemed to be headed for $200 but they seem nearer $100 now, and you can get some fixer upper or take a chance deals at $80 or so.

First signs of an upcoming massive decline in Voodoo prices...
Time to get rid of all your hoarded 3dfx stuff at payable prices before no one wants them any more!

No, honestly, if you think about it, in ten or may be 20 years, who will want or even know about 3dfx stuff?
Who will collect that or even pay money for it? Who cares after this generation that once grew up with it?
It may not be now or tomorrow but the time will come when prices go down again. Don't you think?

By that time itll be Core2 and GTX 200/400 that will be silly expensive, and following that Sandybridge and GTX 500/600.

On a side note I'm selling some things on eBay these days at decent prices, that is about half of what these items with absurd long-term high prices try to sell for and lower than similar items recently sold. And I make a point of testing all the hardware and giving the buyer a video from it so everyone is happy, this takes real time. Well, I still get angry messages from potential buyers telling me that I should basically give them the hardware for free blablabla and that shipping costs are too high...it's insane, I don't make up shipping costs or eBay fees. Sometimes this makes me want to just throw the hardware away and not deal with that.

Bought my second Cyrix processor.

You are right, there aren't many and mostly slower ones.
Still these prices are crazy for a Socket 423 CPU, imho.

People are like that. Each and every day. Sadly.
You can offer things for very low prices (not just computer hardware) and they still try to make a bargain for every cent of it. If you don't follow you won't sell.
But throwing away still usable things also can't be the solution...

Since this thread is about bought (retro) hardware I can add this:

The 5k86-P90 was on my wanted list for a long time. I missed one only some weeks ago (was sold within minutes) but this time luck was on my side.
As a nice addition it came with a Pentium MMX Overdrive which aren't seen that often, too.
Unfortunately the overdrive has a somewhat broken heatsink and a missing fan but it still works.
Since it doesn't throttle without a fan this doesn't need any workaround (separate cooling provided).
In the worst case a socket 3 overdrive's fan works like a charm on it.

P60 non-goldcap edition. Still on the way. Hope it arrives in one piece.

Cyrix didn't have any fabrication plants, so they partnered with IBM, Texas Instruments and SGS Thomson (STMicroelectronics).

Today I received a new (at least new for me) server! Let's get acquainted with the:

Acer Altos 900

Quick specs are:
Pentium 150MHz cpu
S3 Trio 64 pci video card
16 MB ram
WD 4.3GB scsi hdd
1.44 MB fdd
Some Tandberg tapestreamer 5000MB

Nice looking system 😀

Looks like someone has swapped motherboards though....the Altos 900 should have an EISA-based Acer M5 board rather than the ISA-based M3 ( http://www.uktsupport.co.uk/acer/mb/acm3.htm )

Maybe submit a pic of your ALI cpu board to The Retro Web as they don't have that one for the M3 ( https://theretroweb.com/motherboards/s/acer-m3 )

The CPU itself say's "it's ST", so who are we to doubt that it is indeed an ST? 😆

BTW, judging by the small "badum tss" I'm pretty sure PD2JK was also joking.
