The SCSI2Pi project is a further development of PiSCSI, which provides open hardware and software for the Raspberry Pi (except for the Pi 5) in order to emulate SCSI devices. SCSI2Pi can either be operated as SCSI target or as SCSI initiator. This means it can act as a peripheral as well as a computer.
In order to improve the stability and the compatiblity with numerous client platforms and to support more SCSI device types I have re-implemented large parts of the SCSI emulation in modern C++. Atari computers are especially supported, e.g. by ICD compatibility and the SCSI2Pi client tools. SCSI2Pi can even be directly controlled with the Atari.

SCSI2Pi emulates several devices at the same time, like hard disks, CD-ROM drives, printers, a DaynaPort network adapter or a realtime clock. This way you can easily add SCSI devices or a memory card reader to your Atari. All emulated devices are ICD compatible, which is important for the MegaSTE or STs/STEs without an ICD compatible host adapter. This way there is no 1 GB limit for the capacity, all SCSI commands can be used and up to 8 emulated devices can be connected to the MegaSTE's internal host adapter at the same time.
SCSI2Pi also works with Linux-68k and Atari's System V Release 4 (ASV).
With the SCSI2Pi client tools the Atari can exploit the full SCSI2Pi functionality. Files can be printed via SCSI2Pi, the Pi or SCSI2Pi can be shut down, and a realtime clock with automatic daylight saving time adjustment is available. In addition, you can control SCSI2Pi with the Atari.
With the PiSCSI Control app multiple PiSCSI boards, the emulated devices, the image files and much more can be managed. The app can also shut down SCSI2Pi/PiSCSI and the Pi.
In the HDDRIVER forum there is a special area on HDDRIVER, the SCSI Control app and the SCSI2Pi client tools.
