Late, cost reduced vic-20 schematic and board
This repository contains KiCad schematics and "rough" PCB layout for the cost reduced VIC-20, assembly #250403.
Originally hard forked from (this does not appear to be maintained).
The schematic for the Commodore VIC-20 (251027-01 Rev D) was taken from the schematics on zimmers.net with extra detail from the "Vic-20 friendly computer technical manual" and converted into KiCad (Version 8).
