The PETdisk is a simple storage device for the Commodore PET series of computers. PETdisk uses a microSD card for mass storage and uses the PET’s IEEE-488 port. Documentation, schematics, and source code will be provided here. Build your own from scratch, or order a PETdisk in kit form.

PETdisk Technical Specs and Firmware
The PETdisk is available as a kit, or fully assembled.
Assembled and tested PETdisks are available for $55 USD. These units are tested with my PET 2001 or 8032 before I send them out the door.
PETdisk kits are also available for $30. This includes the PETdisk printed circuit board along with all components, including a programmed ATMega168 microcontroller with the PETdisk firmware. Assembly generally takes under an hour, and requires some basic tools (soldering iron, utility knife). If you have issues with the assembly, I’ll try to help debug it. If problems persist you can send it back to me and I’ll attempt to analyze/repair it for you, but you would pay for the round-trip shipping in that case.
The PETdisk has a bootloader which updates its firmware directly from a file on the SD card, so when future updates are available you can easily get the latest features.

Wow – what a great device! Well done!
Hi,
I like a lot your project.
You have a plan for connect a IEEE-488 Centronics connector?
Example for my Commodore 8096SK ;-D (http://www.nightfallcrew.com/?s=8096)
Best regards.
Very cool computer you have there! Where can I get one?
Thanks very much, I think it wouldn’t be too difficult to add an IEEE-488 connector. Without a major redesign, I think the simplest way would be to create a small adapter board with a male IEEE-488 connector on one side and an edge connector on the other. This would plug into the back of the 8096SK, and then the PETdisk would plug into the edge connector. Send me an email at bitfixer@bitfixer.com if you’re interested and we can talk about this possibility!
Awesome stuff! I’m looking forward very much to building one. Thanks for sharing :¬)
This looks awsome!!! An excellent job well done. I have done internal work with the Commodore drives a long time ago. I am very curious how you implemented the drive emulation in the Atmel. It looks very well polished!!!!
Looking forward to having these at The Centre for Computing History for making our Commodore PET display that bit more interactive
Excellent Job!
This is exactly what makes restoring old computers fun and worthwhile, installing this clever little device is a brilliant use of modern technology, very pleased and well impressed, well done!
hi,
thanks, the long-awaited petdisk finally arrived last week.
i am so happy!
thank you very much for your work and enthusiasm!
greetings, mike.
I just bought a Commodore PET 4032 from someone on Kijiji. It came with the PETdisk kit. I must say, very cool!! This will working with my PET so much easier!
