After my recent bad luck with an Am5x86 based SBC, I went looking for other 90s industrial PCs to replace it. This really weird Advantech unit was being sold locally, and while I paid quite a lot less than the asking price, I'm still not sure I'd call it a bargain. Still, it's very interesting!

This Advantech PPC-102 is just really weird, in lots of ways! It's got a Pentium-S 166Mhz, 32Mb 72-pin RAM, SiS 5571 chipset, Chips 1Mb dedicated VGA, ESS 1688 ISA sound onboard. The layout is really weird, with all of the I/O on a daughterboard. All of it sits behind a 10" TFT touchscreen!

Even weirder is the secondary IDE and floppy connectors on a separate daughterboard, so they can only be accessed externally! That daughterboard has a custom connector on the right, but a PCI connector on the left, with only the short part of it actually having contacts. Weirder still, it is labelled as "ISA Connector ", and in the manual as 8-bit ISA. What's going on here?!

When it collected it it was only working intermittently, but as soon as I had it open it was obvious the soldered coin battery was really badly corroded, and there was loads of baked on grime around the SIMM slots. I managed to replace the battery with a 2032 holder, and clean the first SIMM, and all seems to be working smoothly now!
It boots into Windows NT 4 and automatically runs a bespoke packaging control system, branded for Kraft Jacobs, with the product set to a type of Kenco Coffee granules!

I haven't been able to get the touchscreen to work yet. I'll try hunting down the original drivers (I think I managed to remove them by mistake when trying to get the mouse to work - turns out it just doesn't like new PS/2 mice), but the resistive touch screen is probably awful? It's also got a few scratches on it, and the manual exploded view suggests it's a distinct part from the screen, so removing it altogether might kill two birds with one stone?
Not really sure what I'll use this for, but it's certainly an interesting weird "little guy"!
