From the project
Tests of various "circuit as code" tools
An isolated USB interface for the Solartron 7075 DVM, described in SKiDL and laid out for KiCad 10. It plugs into the 50-way Cannon socket (SKB) of the 7075's Parallel BCD Interface Unit 70754 (service manual section 9). From there it reads the display data and status lines, drives all the remote-control inputs, and connects to a host over USB through an RP2354A.
