Bored of reading introductions? The question is at the bottom!
I am in the process of tidying up my stash of old parts in which are a couple of ISA/PCI backplanes, and I am toying with the idea of an SBC build to put under my desk and retire my old thin client.
One of the boards has some potential for getting my soldering iron out and playing around a bit further.
As you can hopefully see from the picture it has 5 ISA slots, one with the PCI slot behind for an SBC board, and another I could solder another PCI slot behind, then two PCI slots, which have the space behind for making into PCI-X.
Power is standard AT, but with two additional pins a quick test of which with the multi-meter shows that is on the 3.3v rail of the PCI slots.
The question I have is, between the standard ISA and standard PCI slots is two back-to-back PCI sockets, any ideas?
They are the opposite way round making them for 3.3V cards, but their alignment seems wrong, was there ever double PCI SBC cards? Had a quick google search for back-to-back PCI / PCI SBC this morning, but can only find the PCI-E equivalents.
