About the VIC-20-Reloaded PCB
VIC-20-Reloaded is an open source PCB design by RichCini, published on GitHub. It is a 2-layer board measuring 263.1 × 136.6 mm, with 130 components from 69 distinct parts.
Other key parts include the 74LS08 and 2016. By type, the board carries 41 capacitors, 28 resistors, 18 inductors, 11 connectors, 3 ICs and 2 transistors.
From the project
Reimaging of the original VIC-20cr ("cost-reduced") main board in a smaller footprint.
Prior Release (1.1-002D): An error was introduced in this version as a result of rearranging the data bus lines lines on IC UF8 (74LS245). D4 (pin 4) and D5 (pin 5) were reversed. There is a picture (ECO001) which indicates a convenient place to cut two traces and cross-wire them. Will be fixed in the next version.
