SpaceSalmon
Space Salmon is the second generation (by some counting) rocket flight computer developed by SSI. It was preceded by the Skybass flight computer.
SpaceSalmon built on the previous generation SkyBass flight computer. Unlike SkyBass, which was a rectangular PCB that mounted vertically I'm the vehicle, Space Salmon was built onto a circular disk-shaped PCB, which fit into the rocket horizontally. This disk stacking arrangement (known coloqially as "Stack Boi") was intended to compactify the avionics and reduce mechanical weight.
The avionics stack used two 12-pin headers for electrical connection between boards. The A-Stack carried power, arming, and data bus lines, while the B-Stack carried charge activation lines downward to the bulkhead.
