RetroBSD is a port of 2.11BSD Unix intended for embedded systems with fixed memory mapping. The current target is Microchip PIC32 microcontroller with 128 kbytes of RAM and 512 kbytes of Flash. PIC32 processor has MIPS M4K architecture, executable data memory and flexible RAM partitioning between user and kernel modes. The project is open source and hosted at RetroBSD.org

PIC32-Pinguino was used by RetroBSD developers since long time as it’s small and easy to use, but the Pinguino bords processor PIC32MX440 has not enough RAM to hold the RetroBSD, so we got number of requests to release PIC32-PINGUINO-MICRO with PIC32MX795F512H processor which is pin to pin compatible, so we run small batch of these boards and named them PIC32-RetroBSD, these surely can be used with Pinguino and MPIDE, but note that you must have additional PIC-KIT3 to re-flash the proper bootloader, as RetroBSD bootloader is different and we ship these boards with RetroBSD bootlaoder. Also you will need PIC32-RetroBSD-SD for the file system.

We are shipping today free PIC32-RetroBSD boards to the 9 RetroBSD developers.
