This is a replica Printed Circuit Board (PCB) derived from the Commodore VIC-20 8-bit computer.

The board was created to allow Commodore VIC-20 computers that have damaged or faulty PCBs to be successfully repaired. This can be achieved by moving all components from an original board to the replica board, or even replace some parts with more modern alternatives.

We currently have 1 x replica board model available:

• Assembly #250403

Assembly #250403

This board design was one of the later used by Commodore. It uses the 7-pin DIN style power connector as opposed to the earlier 2-pin 9VAC models.

Other Information

Over the past 30+ years, there have been many boards that have become damaged for various reasons such as poor storage conditions etc.

The replica boards are of the same dimensions of the original and can therefore be used as a direct replacement to the original PCBs.

Some improvements/modifications were made:

• Improved silkscreen, adding more descriptive connector labels, IC names and better placed component labels
• Manufactured using modern PCB manufacturing techniques and materials.
• Corrected factory "bodge" around the video area.
• Removed the need for link wire near FB4 component.
• Extra GND holes on DIN connectors to allow for a larger variety of replacements to be used.
• 9VAC wires that were originally connected across the board for power to the User Port have been replaced with 0.6mm traces so the wires are not required. The connections are still there if you would prefer to use the original style wires.

Prototype boards were tested to ensure no issues were encountered.

Optional Extras

Some replacement components can be purchased along with the boards:

• Resistor Packs, containing all required resistors for the specific model of board. All resistors are new metal film resistors.
• New replacement power switch - Recently manufactured new power switches available.

Other available component packs and addons will be added as they become available.
