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:
