The DX-50 predates the VLB era, and considering the VLB bus, depending on the indivdual cards, sometimes has problems even running at 40 MHz, you can see why it is hopeless running at 50 MHz. I think that was one of the reasons for the introduction of the DX2-50.
I had a 486DX-50 system with VLB back in 1991. My Promise IDE card and Diamond Stealth (S3 Vision) VLB cards worked fine at 50 MHz.
I stand corrected.
Can't imagine what that thing must've cost in 1991!
Allright, I give: what's the reverse PCI slot at the bottom of this thing? I'm aware of 3.3V PCI slots but they're not offset towards the back of the board like that one is. It looks like you could stick a normal PCI card up-side-down in there if you took off the end plate?
Nah... IIRC they were proprietary and used for modems and such. Like AMR/CMR.

Sorry, but since I've done alot of research into building a DX-50 system, that can't be correct.
VLB wasnt released until 1992, and didn't really become common until 1993. https://en.wikipedia.org/wiki/VESA_Local_Bus
S3 Vision series wasn't out until 1993 as well.
*Some* of the S3vision boards (the ones that use DRAM) can work at 50MHz. I heard S3 968 does not handle it well. I am too affraid to fry my card trying.
EDIT: And I think you may be misremembering, unless it was a cut-down special; a quick Google search doesn't turn up any obvious 32MB 8500s.
I have also never heard of a 32MB 8500. Only 64MB or 128MB.
9000 OTOH does come with 32MB, especially the mobile variant. The memory interface is reduced to 64-bit in that case.
Yep, the Mobility Radeon 9000s have 32MB of RAM in the Dell Latitude D600s I've owned.
I always wondered if having one of these cards in my system could make it ideal for using a Playstation 1 emulator and ROM's. Not that there aren't better 3D cards which could do everything the PowerVR cards can do, but at least you could use it in it's genuine role. I'm not sure how the speed of one of these cards compares to the on-board PowerVR in the Playstation. But obviously, these cards are driven harder, the faster your processor/motherboard combination is. I don't know if the card can be driven without error over an overclocked PCI bus, but since even modern motherboards can be found with 5V PCI buses, it could be fun to do new benchmarks and overclock experiments with it.

I think you might be mistaken here, as far as I know the Power VR was used by Dreamcast and that was PCX2, the Sony Playstation had no connection to the Power VR.

I made a mistake on the Diamond card. It is actually a Diamond Stealth 64 DRAM VLB, a Trio64-based card. I still have it (along with the Promise card). Here is a link to a thread on it: Diamond Stealth 64 DRAM VLB + memory upgrade = burning smell!
My memory may be fuzzy, but I'm almost positive this was 1991. I remember because that's when I started grad school, and I had some money to buy a cutting-edge system. Possible that I bought it in 1992. When I have some time, I will check the Diamond and Promise cards for dates.

It's ASUS' proprietary ACR (Advanced Communication Riser). From the manual it supports "modem, audio, LAN" risers. It appears you have the option between enabling that slot or using the USB#3 header on the motherboard via jumper.
Apologies to oerk and everyone else, but I think my memory is failing me in my old age. I couldn't have obtained a VLB motherboard until at least 1992 and maybe 1993. I suspect that the Diamond card is from 1993 or 1994, given that the Trio64 was the successor to the Vision series, correct? The only thing that I am certain about is that I ran a DX-50 on my VLB board. Sorry for all the confusion.

Its what I tend to call an "Extended AT" case, for those four extra expansion slots above the keyboard, exactly what you need for such amazing boards as an Supermicro P6DGH or an Asus P/I P65UP8. Along with that it has a standard power supply mount, two 80mm fan mounts, one in the front for expansion cards and one in the back. There's two external 3.5" bays, five 5.25" bays, and three internal 3.5" bays, a 3 digit CPU speed indicator, and IMO, the best power switch in existence 🤣
Sadly, as much as I would like one I can't find the board I would like to put into it: A Supermicro P6DGH, a dual slot 1, 440GX monster that could very well be the fastest AT board ever made... (Although, http://www.interloper.com/products/product-de … rch_str=bsearch does sell a P6DLH, which is limited to a 440LX chipset and the slower FSB and lack of AGP that comes with it) I did pick up a brand new motherboard to fit into the case until I could track one down!
I got a brand new, open box, Tyan Tsunami AT ( S1830 ) off of eBay for $75 on an offer. http://www.ebay.com/itm/231621384263 The person selling them has another 48 more and seems very willing to take offers along with their lowering the price fairly regularly, for anyone who wants one.
Anyway, specs on the board: 440BX chipset w/ 100mhz FSB support, 1x AGP, 4xPCI, 4xISA, and will take 1GB of SDRAM, and I have every reason to believe will accept my 1.4ghz Tualatin Celeron with my Powerleap slotket. It also doesn't lose any of the built-in I/O you get with ATX 440BX boards, and has the connectors for PS/2 mouse, dual serial, parallel, and even USB on the board, ready for connectors to be mounted to the case. A very solid board and I look forward to putting it to use!

Ick, just looked up some info on those. What a horrible design choice for an apparently useless slot. My first assumption would be that it's there to put something like an internal drive controller or watchdog board in upside-down and a normal card in the same slot space. I'm guessing Bad Things Would Happen if I did that.

This item should arrive tomorrow. The only retro item I've been actively hunting for is a wavetable daughtercard at a reasonable price. This is the Diamond Monster MIDI 4MB. I've read generally positive things about this board on Vogons.
One question I have: Can this daughtercard also be used with an ISA soundcard with wavetable header, such as the SB16?

I don't know that yet. Have been puzzeled about this too. Hmmm... I just have not had time testing all of my haul yet.
As you can see. It was some giant one I made. Like 5 motherboards and other stuff. Including that P-166 AT system,
wich was complete and in working condition.

Don't eat stuff off a 15 year old never cleaned cpu cooler.
Those cakes make you sick....
Recieved my STB Voodoo2 today. It even came with a manual and a driverdisc.
I swapped an AWE64 for it, as I had too many of those and was missing a single V2-12mb for SLI.

I wouldn't pay 75$ for an AT slot 1 motherboard, even if it comes with a box - but that's just me. I usually pick up slot 1 AT mobos for about 10 euro, and that's as far as I'm willing to pay for them. I'd rather use my AT cases for AT motherboards, like a super socket 7 witch can mostly be found in AT format (around here anyway) a socket 4 or a socket 3 board.
