Thank you for sharing. My PCB paraphenalia: pads, handtape, and other masking materials; have sat unused for decades. My project for today is to migrate from a PAKRATT PK-232 to an All-in-one-Cable (AIOC). A company named Advanced Electronic Applications built the PK-232 back in 1987. Its PCB brims with chips:

The AIOC fully replicates PK-232 functionality, and adds many more modes. It's essentially a STM32F302 surrounded by I/O interface components. Here's a picture of the component side:

And a picture of the other side:

Danke,
