# Prophet-600 CPU Upgrade
|
|
|
|
This repo. is for the CPU upgrade module I am designing for the Sequential Circuits, Inc. Prophet-600 synthesizer. The firmware for this module is [Imogen's P600FW v2022](https://www.image-et-son.com/), a newer and updated version of the famous [GliGli P600FW](https://gligli.github.io/p600fw/) mod. What's different is this board replaces the need for a modified Teensey++ 2.0, as it has the same AT90USB1286 microcontroller wired to all the same pins, except for the ones that need to be modified as per the original instructions.

Information about the original Teensey++ 2.0 board this is replacing: [https://www.pjrc.com/store/teensypp.html](https://www.pjrc.com/store/teensypp.html).

My plan is to build up one of these boards so that I can upgrade my Prophet-600 and get some better use out of it making music.

# Board Revisions
|
|
|
|
## Revision 1.0 - March 2025
|
|
- Created the board based off the original Teensey++ 2.0 pin out and GliGli's modification instructions
|
|
- The board uses (for the most part) SMD components. The USB port is hybrid and the pin headers had to be through-hole.
|
|
- Board component choice is based off of the components used on the MacroPad Project.
