Summary note:
In this project, we successfully restored a Digital Equipment Corporation (DEC) PDP-8/L minicomputer and interfaced it to a modern laptop. During its restoration, we repaired the power supply, replaced a defunct cooling fan, fixed the front panel, repaired the core memory, created a library of basic programs on an emulator in PDP-8 assembly language (PAL), ran extensive diagnostics on both the CPU logic and memory stack, and designed an RS-232 to current loop interface to allow the PDP-8 to communicate with the terminal of a modern laptop.
