PC/104 Architecture
Any one familiar with it: PC/104+ in particular? Im looking to install a PCI adapter card but theres a massive difference between supporting PCI and actually installing one successfully.

Im waiting for a touchscreen industrial PC to arrive, I havent seen it yet. Im not familiar with modular architecture and whilst I know that 104+ is compatible with PCI architecture: I dont understand how exactly you fit a PCI expansion card, if you can. Im guessing that an adapter board fits into the 104+ connecter on the system board?

The signal feeds signals up through the stack, so aslong as the PC/104-Plus peripheral cards in the stack do not exceed four module slices you will be fine, else you will need a bridge. All moduels are controlled by the motherboard controller.
You sure its not PCI-104 or PCI/104-Express? 104Plus is very old.

The PC/104 spec defines the size of the board (about 3.5" square) and the 0.1" pitch connector at one end. This connector carries power and a set of signals which are electrically the same as the old ISA bus.
PC/104 Plus builds on this spec, adding a second connector - the 2mm pitch one along the opposite edge of the board. Electrically this carries a PCI bus, though the connector obviously can't accommodate a PCI card in the desktop PC sense. You might be able to source an adapter card but I've not come across one - normally you'd use a PC/104 Plus version of whatever card it is you need.

Looks as though you need to spend a while on Google to find an adapter then!
I can't see how it would work mechanically, though, the whole point of PC/104 being that it's much smaller than a desktop motherboard. I've found adapters to install a mini-PCI card on PC/104, and to install a PC/104 card in a desktop PCI slot, and even PC/104 into CompactPCI which is something else again. But no PC/104 card with a desktop-sized PCI slot, sadly.
If you did find one then I can't see why you'd have any real problem making it work - you might just have to set a link to specify where IDSEL comes from, that's all.

Why would a company buy 104+? Homebase for example use pci on their touch screen computer tills/SAP integration. Its really old and limited support, seems a bad move unless there are techs on site?
It must be PCI?

Depends entirely on what you're doing. For example, here is a ruggedised enclosure designed for vehicle mounting, which can accommodate a PC/104 stack. It's a much more robust form factor than, say, mini-ITX or any other format that uses edge connectors. Here is another, built like a tank and designed to be installed in one.
