ebay item #8760295547, prototyping board
Card edge connector with 44 contacts, 22 per side, 0.156" spacing
Is this STD bus? I'm not planning on buying it, I was just
curious :)
This 44-pin protoboard system was popularized by Vector and you could buy
"backplanes" (either bare or bussed) as well as several different types of
proto
boards up through the 90's. They were on the shelves at Radio Shack for a couple
decades. I think the boards are still available but the backplanes
are not ready-made anymore.
These were largely used for special-purpose one-off hardware designs, although
certainly some did use them in bussed systems. 44 pins is a little sparse for a bus
for an 8-bit-data-16-but-address system (although doable). Even the 100-pin S-100
bus didn't have enough grounds!
