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
PETdisk kits are available for $25. This includes the PETdisk printed circuit board along with all components, including a programmed ATMega8 microcontroller with the PETdisk firmware. Assembly generally takes under an hour.
When firmware updates are available, you can reprogram your PETdisk with the new code using a simple serial programmer. Plans are in place for a bootloader which will allow you to upgrade your firmware directly from the SD card – watch for more details when this becomes a reality.

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!!!!
