Origin of 0.156" (3.96mm) pitch edge card connectors?
« on: March 18, 2019, 03:34:10 am »
Does anybody know where the once-common 0.156" pitch (3.96 mm) edge card connectors originally came from?

I remember in the late 1970s the 44 pin (22 per side) edge card connector was very common in microprocessor systems, etc.

Why that pitch? It seems like an odd number. Does anybody know how it originated?

  • If you can buy it for 4$ on eBay, why design it?*

*Except AC/DC adapters on eBay. Avoid them all!
