Could be a Jetway P2 board of some kind. They commonly had white I/O connectors, I think.

Or a Lucky Star. Compare the looks with this board:

I really love these kind of controllers. Good catch.
I am actually looking for controllers like that too.

How about this one?

Thanks brostenten 😀

Might sound stupid, but I think chache controllers add a lot of flavour, really improving "cool factor" of any build, even though cache may not be useful at all if you use CF card. I want to get any ISA slot in my PC pupulated with something interesting and cache contoller does the thing 😀

Wow, I think you are spot on, except that what I got seems to be a Ver 3.0, and possibly a 6ABX2 instead.

It is in my watchlist. I just do not have the money right now.
No secret that I am hoping that it will be up for sale when I have money for it.
First. I need to source AT cases. And I have found something, somewere.
I only have to wait untill payday.

Yeah.... It is my exact same thought as well.
Another thing is that they might give better compatibility with newer drives.
Who knows.... They might or might not.

Another thing I am trying to save money for, are those IDE/SCSI converters.
I have seen one special one, that converts a 2.5 inch PATA to 68-Pin SCSI.
Having 68-pin, can then be converted to 50-pin, and the result is a cold-
running SCSI harddrives. They are however expensive. Really expensive. 🙁

I have two 9gb 10.000 and three 4gb 10.000 rpm IBM SCSI drives.
They are loud as a jet engine, and they get extremely hot.
So I am looking for a better solution, that run quiet and cold.
If only I knew how much those five drives are worth, I would set them
up for sale, in order to get enough money for a converter.

Well then I will edit out the link.

This is the wrong thread for links to non sold Ebay auctions anyhow so it's perhaps best you also edit out the Ebay link...(which also increases the chanse that the item dosn't get sold while you gather the funds ten fold).

True that. 😀

Here's a bit of a tip on how to score a SCSI converter on the cheap: keep a lookout for "SCSI" optical drives, which are actually IDE drives with a converter slapped on the back of it. Usually the seller doesn't know this and presto; you have a SCSI to IDE converter for the price of a SCSI optical drive. Compatibility might be an issue, but I gather that's the case with all converters.

I recently bid on one that went for ~20 EUR. Good price for a converter, but still too much for a cheapskate like me. 😉

I like the idea of shoving as much "memory" into a machine as I can. I've got 64MB in my DX2 right now, and I plan on maxing out my SB 32 and putting in a maxed out cache controller.

Sellers photos.

My new mobo does not have a game port header so I needed a sound card with one. As far as I know this and the audigy 4 pro are the best two cards with a game/joy stick port.

Finally own a 486 system backbone. Did I do good?

I have no idea how a UMC U5SX 486-33F performs compared to a i486DX33 but it can't be too bad I guess.

Obviously I can't use it with my DX4-100 CPU (my initial 486 build goal) but that's fine, I now have a Pentium MMX system to cover that era.. Now, to find an AT Case for this board 😀

That's a very interesting board. I guess it was designed to be as cheap as possible by a) making the footprint tiny b) including compatibility for 30-pin SIMMs so that upgraders didn't have to buy new RAM c) including support for 72-pin SIMMs for when you could afford to upgrade (but I've NEVER seen only 1 slot) d) integrating as many components as possible, even the keyboard controller e) no cache whatsoever. This, and the lack of option to install a co-pro (which could only have taken the form of a 487 anyway, which is a drop-in Intel DX that deactivates the SX) are the two factors which will make the performance of this system extremely sucky compared to other 486 possibilities. In fact, a 386DX/40 would probably outperform it easily.

BUT if this is your only 486-class system, it'll make a great platform for early VGA games and, like you say, you have an MMX system for Doom and the more demanding games of that era.

It's an extremely quirky all-UMC board. I like it!

Interesting read. I didn't expect that sucky performance when buying it to be honest, my research online seemed to indicate around 486SX2 levels of performance out of this, but alas, it is what it is. If I ever build something around it, it will be an MS-DOS 6.22 machine with a GOTEK HxC, 16-bit sound and good old ISA SVGA, something to play pre-1994, pre-CD-ROM games on. It should be fine for that, I would think.

Anyways, the board seems to be almost identical to this:http://www.amoretro.de/2012/09/mb457-v1-1-umc … -33mhz-cpu.html except that the one at the link has an Award BIOS and this has an AMI BIOS.

I suppose the barrel battery has to go right away? It can be replaced by a CR2032 battery holder?

I disagree. The UMC U5SX is actually faster clock-for-clock than an Intel SX, and the lack of L2 cache doesn't matter that much since it does have L1 cache. So, I actually expect this to perform better than an Intel 486DX33.

Pretty cool and interesting board, i also think it should be much faster than a 386. And the UMC chipset was fast.

Let's hope it runs with an 8MB 72-pin SIMM, I have no 30-pin SIMMs 😁

Got my self some soundblasters.

No idea what the CPU is (asked the seller and he quoted the sticker on the BIOS chip..) or how much RAM it has (did not ask after the first question) but he swears it works, so I paid around $20 for it, a floppy drive and 2 DVD/CD-RW combo drives. If anyone can ID the board from this lousy photo, humour me 😀

I want to turn it into a 99/00 gaming PC.. I want to add a Voodoo 3 to it, but I have none and finding one would be a hassle. The only Voodoo 2 I have is in my MMX build. I guess that means I may buy and use a TNT2 for the first time.. GeForce 256 is not an option, as it's almost as rare as the Voodoo 3 where I live. So the only other option is GeForce 2 MX 400 (which isn't time accurate but actually fairly decent for such a rig..)

I may end up getting both a TNT2 and an MX400..

This just arrived and I don't know whether to be happy or disappointed. The board is a Lucky Star 6P2BX2 which is ok and it has the 256mb PC133 ram but the cpu is not a P2 350 but actually a P3 450.. Which isn't bad and all but not very useful as I already have an ongoing Tualatin Celeron 1300 build so currently I have no idea what to do with this. I could stick an i740 and move my V2 from the MMX to this I suppose as it would much better suit the era.. but the Voodoo 2 feels just right in an MMX PC for me. This board/cpu is begging for a Voodoo 3, I hope I can find one..
