The A600 PiStorm is a special version only for use with smt 68000 processors like the one in the Amiga 600.
It presses/clips over the processor, disabling it, replacing it with an emulated, accelerated 68000 via a Raspberry Pi.
The Raspberry Pi is NOT included in this listing, but a Pi Zero 2W (shown) or Pi 3A+ are the recommended versions that fit.
Acceleration and CPU upgrade (up to 68040) is not all it does though.
Using EMU68, it also emulates SCSI drives/partitions on the inserted SD Card, Picasso GFX card over HDMI, over 300MB of Fast Ram, Kick switching, DF0/DF1 boot swapping etc.
These partitions can also be loaded in the WINUAE emulator to make installing and transferring of software must easier/faster than the old floppy disks.
Each pistorm comes flashed with the standard firmware suitable for EMU68, but it's not hard to change this using the Pi itself and a clean 32 bit OS install.

My recommendation is to seek out Caffeine OS, a preconfigured image you write to a 32Gb SD card or larger.
I am also selling a 1MB chip RAM upgrade with RTC (real time clock) in another listing.
