Using a Raspberry Pi Zero SCSI adapter to bring legacy and retro systems into the future #PiDay #RaspberryPi #SCSI
Via James Sanders on techrepublic.com – hard drives for early computers are decades old and prone to failure, prompting a need for modern storage adapters.
RaSCSI uses the Raspberry Pi as an SCSI target device emulator. RaSCSI was designed by Japanese hardware hacker GIMONS, with physical devices produced by Akihabara electronics shop Kenchan. GIMONS provides the documentation for others to produce the physical hardware needed, making it possible to create your own, provided you have working knowledge of electrical design. Of note, earlier variants use the full-size Raspberry Pi, though the Kenchan variant is the first to use the smaller Raspberry Pi Zero.
The RaSCSI is capable of acting as a virtual SASI/SCSI disk, permitting the use of floppy disk, CD ISO, and virtual hard disk images loaded from an SD card. The system is interoperable with classic Macintosh, Windows systems, and Japan-exclusive home computers, including the Sharp X68000, NEC PC-98, Fujitsu FM-TOWNS, and MSX.
Source code for the RaSCSI server software (which runs on the Raspberry Pi) and X68000-specific components for file system and tap device relays are available here.
