Best PC104 for the "job"

Not too many PC 104 topics are floating around here, most likely cos most people still cannot afford them. Even for the old pos AMD 586, P133 modules sometimes they charge well over 600-800$. Kind of overkill for 20+ years old technology but let's get to the chase:

I looking for these machines from 2 perspectives:

1, The "most compatible", will run most retro OSes with full hardware support: Win9X/NT/2K/XP/Novell/Solaris/Linuxes etc.

So for this the most limiting factor I found is the embedded network card, some of them have some weird industrial ethernet which does not work with many OSes.
The second is booting issues, I use these all from the CF cards on them and some have weird setups like that shows up as SDB SDC so 2nd 3rd hdd which crap in many retro OSes.

2, The "most powerful" still can be used for retro purposes but you can run high end games on them like Quake3

Now for this the VGA (if there is any LoL) is the most limiting factor. Many of these PC104s are with these 500 Mhz AMD Geode processors are powerful enough to run the beforementioned retro OSes and many old games what it comes down to is the graphics card which is more often than not is dogeshit squared on these boards. Many doesn't even have any you need to buy the expensive external one for an additional 2000 euros 😁

What they do have is ISA/PCI ports so with an expansion card you can pretty much plug in anything PCI like good old Voodoo2 Voodoo3s.

I managed to get good results on some with the VBEM driver in 9x: https://bearwindows.zcm.com.au/vbe9x.htm
These were boards where the manufacturer didn't even provide 9x drivers anymore.

Feel free to share any experience with the PC104 boards you tried. Please keep the topic clean those who never owned/tried any don't comment. Huge advantage of these boards is many of them are completely silent, you don't need fan so they are zero noise, no mechanical hdd again because you use the CF, regardless that whether fully supported in hardware or not almost all retro OSes will run on them because they are X86 and the CF adapter == IDE and we there many can run with a 5V2A regular power adapter without needing a big bulky power supply.

I have an ICOP 6071 (though the firmware is branded Contradata), mainly on the basis of it being the only PC104 mobo you can find here in Italy (at all, and) for a 2-digit price 😀

The attachment s-l1600.jpg is no longer available

Lots of bells and whistles there - it's the very first Vortex86 so 586 class instead of 486, a floppy connector (surprisingly uncommon), 4 serial ports (wOw), VGA, AC97, USB, Ethernet (Realtek 8100B, which should be pretty common as far as support goes?)

I actually kinda regret using maybe 20% of its potential, as I have only wired the two PS/2 ports, VGA, one serial, the PC Speaker, a FDD and a 1200 MB mechanical hard drive 😀
Can't really comment on VBE compliance, it's just something I've never looked for, plain VGA text mode works and that's fine for my needs...
Feel free to ask if you want me to try something on it, though 😀
Also most every connector is 2mm (like 44 pin IDE), luckily the box includes adapters for almost every socket but the RJ45 one is nasty, being a cube with wires sticking out and no real way to mount it to anything!

Of course, barely 2 months after I bought it, another cheaper model came (and went), with more customary 2.54 mm connectors and onboard RJ45 but no integrated graphics, which I confirm to be a sore point (Monotech does make PC104 VGA cards for the NuXT, but that's across the world and I've never seen one in person either, and even using a PC104 to ISA adapter [which start at 130 € on ebay, I suspect it would cost less than 30 to make from scratch in the quantity of 1] wouldn't be particularly useful as nobody within 200 km of here seems to be selling ISA graphics cards of any grade) 😀 🙁

What I found rather interesting while researching these products is how both companies (Contradata and Seco) are based in Arezzo!

Thanks I might give your board a try but I looking for a bit more power under the hood than that 😁

Well here is some of my experience so far:

Advantec PC104 PCM3370 (good hw support)
CPU Intel Celeron 400Mhz 06B4/00
Realtek 8139C ethernet
256 mb ram
"S3 GraphicsTwister"

I would say this takes the cake for best hw support with that rtl card, no wonder that I use this for Novell server, many versions of Novell supports this.
Only problem with this that it's an eggcooker power hungry celeron, it needs both +12V and +5V power sources and active cooling.

MICROSPACE® MSM800SEL/SEV/BEV

vendor_id : AuthenticAMD
cpu family : 5
model : 10
model name : Geode(TM) Integrated Processor by AMD PCS
stepping : 2
microcode : 0x8b
cpu MHz : 499.612

Problem with this is unsupported ethernet plus I could not boot anything but Linux on it so far also netboot not even pxe but bootp...

This one maybe the best I used overall but difficult to find and expensive. Network is also 8139C. No win98 driver for the VGA, works fine with VBEM even up to Quake3.
