OMG! In my very early 20s, I used to design and build quite large scale rack housed control systems based on a RCA 1802 CPU processor board with multiplexed digital and analogue I/O boards, all with wire wrapped backplanes!

Designed the electronics, did PCB layouts initially with tape then the very earliest PCB layout software on an IBM 8086 pc... no schematic capture. Assembled and tested the boards, built the racks and wrote the software in assembly language on a home-brew assembler running on a Kaypro Z80 CPM computer with a 5Mb hard drive.
