Product Information
Specification

The COMIX-35is an open-source clone of the 1980s COMX-35 8-bit home computer.

It uses the RCA 1802 microprocessor which is strange and slow but holds the distinction of being the first CMOS microprocessor.

The "35" is because the original computer has 32K of main memory + 3K of video RAM.
