Boards in 3 GitHub repositories, designed in KiCad, that use the CDP1802E by Texas Instruments (- Microcontrollers (MCU/MPU/SOC)). See how each wires it, with its parts, size, README and files; the CDP1802E’s symbol, footprint and pinout are on its own page.
tebl/RC1802-Cosmac-ELF
With the RC6502-project for making an Apple 1 replica done I wanted to do something different, so I started designing a simple version of the RCA 1802-based Cosmac ELF instead.
tebl/RetroShield1802-PCB
Arduino Mega 2560 shield adding secondary 1802 processor to run the latest 1802-based software (most may be from the 70s).
