SGS Thomson made quite a few 486 chips back in the day, I remember having a DX2-66 - and that is what this probably is, a regular DX2-66 with 33MHz bus.

If it's like this: https://www.youtube.com/watch?v=OAhbsVbVLoI, it's probably single-clocked on a 66MHz bus. The description of the product says DX-66.

edit: It definitely is. Same STPC chip which contains the CPU.

wow guys.
Never heard of them before.

Any clue about, besides the clock, how do they compare vs Intel 486 DXs in terms of performance in different areas, architecture, etc.?
Compatibility? MS-DOS, Windows 3.xx, etc.

How would you hook somehow a good SVGA to that thing/module?
The diagram mentions a "PCI BUS" to which the Ethernet port is connected:
https://www.artisantg.com/info/ATGmgxkf.pdf

Then, I wonder, Vogons' experts could be able to grab iron, solder, and wires, and to "manually" interface an "external" piece of PCI slot (like a PCI riser or things like that) to the existing PCI BUS, so to also have a couple of slots besides the Ethernet port, would that be possible?

Thanks

I expanded the question above, showing the link to the product diagram mentioning a "PCI BUS".

Thomson second-sourced for Cyrix, so it should be a relatively normally performing single clocked Cx486 (but on a 66MHz bus). I couldn't find the Cx486DX-33 in the Ultimate 486 Benchmark Comparison to compare speeds with, say, a 486DX2-66, but the DX2 comparison from Cyrix to Intel isn't a big gap. Their DX-33s shouldn't have a big gap either. It probably ought to be about Intel DX2-66 level, maybe a tiny bit over. Compatibility should be pretty good since it'll be meant to be running legacy industrial control software anyway.

The SVGA it has might actually be pretty good. It seems like according to its datasheet it attaches over PCI and has decent 2D acceleration. It also might? do MPEG decoding but I can't puzzle it out. If you wanted your own card anyway you might be able to find adapters for the PC/104 Plus interface it has on the top/bottom. They have full ISA and PCI bus signals. There's no reason a PCB couldn't be made up to break it out into proper slot connectors. I'd kill for one for my 386 PC/104 SBC.

oh its an advantech pc/104 module. pc/104 is basically an isa bus slot more or less. from 2006.

advantech make HEAPS of isa sbc + picmg boards and pc/104 modules.

wow interesting!

But:

• Isn't the PC/104 connector interfaced with the ISA bus?
https://www.artisantg.com/info/ATGmgxkf.pdf
A PC/104 to "slot" adapter would ISA-bottleneck the video card, right?

• Where did you read on the datasheet that it attaches over the PCI?

• Wow, how I wish I was able to make that PCB thing!

• You're right, I didn't look closely enough at the board itself. It lacks the "Plus" connector that would carry PCI. It only has the ISA PC/104. It probably would bottleneck an SVGA card.

• I couldn't find anywhere on the datasheet for the SBC itself that said it attaches over PCI, but I found the datasheet for the SVGA chip itself and it says it'll do either PCI or AGP. I don't think it's attached over AGP.

• It might not be that hard to lay out. Now that I've already given the idea away for free it might be my first experiment in board layout. 😜

Wow, I wouldn't even know where to start!

And where in the world did you find the name of the SVGA chip???

I think somewhere on the board's page or its datasheet it mentioned a "C&T 69000", which would be a Chips and Technologies 69000 SVGA chip

Also, this is the manufacturer. There's good stuff here it seems:

PC/104 I/O modules provide IDE to CompactFlash module, ISA Bridge module, and ISA module in PC/104 form factor:

Embedded Single Board Computers:

PCI to ISA Bridge Module:
http://www.advantech.com/products/1-2jklug/pc … 7a-30bcd6aee42a

That IDE I/O module looks pretty useful. The SBC has a 44-pin laptop-size EIDE interface anyway, but the I/O supports CF and full-size 40 pin IDE. SBC itself could take a 44-pin IDE DOM SSD though, shouldn't even need a molex power connector for it.

PCI to ISA wouldn't work with this one. It's to use PC/104 modules on a SBC that only has the PCI/104 interface. (which differs from PC/104 Plus in that it lacks ISA signalling and only has PCI)

It's making me want to build another compact PC from SBCs. I have one made from a 5x86 SBC with an ISA interface and backplane, but now I want to roll my own backplane board and make it extra small. Amiga size maybe.

Am I inspiring you with your project eh? 😁
Yes, the mini-computer already has a slot for a CF card SSD, which is interfaced with its PCI!!! Very good!

FFS I need to just stare at the board for a bit and stop overlooking things. Completely missed the already-present CF card slot. There's a pin header for a proper (but 2.5") IDE cable on the other side though. I'll probably use the board I already have, a PCM-3336, if I actually do anything.

oh yes sure, I forgot to mention. The IDE connector is also PCI-interfaced

Looks like there's USB in the mix. I think the Advantech board might have a separate SVGA? Non-SoC video looks like it might be optional.

SoC = "System on Chip", normally.

Here's another one that looks interesting (because Am5x86 CPU):

And here's one with full Socket 7 CPU support up to 400 MHz and a 4 Mb PCI integrated video card:
