[sdiy] backplane connector recommendation?

[Mike Pepper]

Actually, I'm also working on a project that needs to connect several
cards to a backplane. I was thinking of using ISA or PCI style PC
motherboard connectors. My only concern is finding a reliable
long-term supply. Jameco carries them, but they actually seem to be a
little scarce otherwise.

or here's the search for all of Jameco's card edge connectors

Any thoughts? Dave, would any of these work for your project? Some can
be had for under a dollar each, so the price is right.

Having worked on a lot of industrial controllers, the one that springs to
mind is the DIN 41612 series. they are very reliable, and if you only want a
small number of pins, just parallel the pins on the multi way ones. I have
bought both plug and socket on ebay for 40p each. There are eurocard sized
protoboards that they fit on, and loads of options including wire-wrap. You
can use a piece of stripboard for a backplane with the one or two row types.
I've thought for a while of using them in a digital/analogue hybrid I'm
messing with the design of. You can even buy ready made extender cards.
