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:

I designed this back in the late 70s .Third iteration, manual layout with tape... 8039 processor 2716 UV eprom. It's missing the twin LCD display that was above the eprom. Measured time/distance etc.https://www.dropbox.com/scl/fi/z5hx6cz3pbfl3hgj7f39j/

An actual socket? I remember the individual pin socket strips.
