Commodore 7: common questions

What microcontroller does the Commodore 7 use?

The Commodore 7 is built around the SN74HC74DRG4 (SOIC14), from the PIC family.

How big is the Commodore 7 PCB?

The Commodore 7 measures 46.8 × 64.2 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Commodore 7?

48 components, from 31 distinct parts. The full bill of materials is listed on this page.

Where can I download the Commodore 7 design files?

From the parsa-novin/UGA-IREC repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Commodore 7 design in my own project?

The repository has no license, so all rights stay with parsa-novin. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Commodore 7 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug PIC firmware against it before you order a PCB.
