Daughter board Mounting Clarification

[kresty]

Those look amazing!!!!

Basically they had header pins on the backs that plugged into the sockets (so they replace a chip).

The originals were "found" circuit boards from old dead electronics. Most of those found boards were just sockets with chips (obviously), and they varied between droids (unclear to me which may have been screen used, I'm not sure that our "canonical" references are actually screen used.)

Anyhoo, what happened with boards like that sometimes is that they were built for multiple purposes &/or modified. Apparently someone decided that the circuit didn't have an appropriate chip or that it wasn't wired right or they could make it better or something, so they replaced the chip with a little daughterboard to correct whatever the deficiency was.
