LC-SCSI

Low-cost SCSI emulator project based around the STM32.

Status: Planning - check the wiki

Aims:

• Emulate SCSI HDD Target, SCSI 1
• SD Card for storage
• Low Cost, target BOM <$10USD
• STM32/GD32 as the target controller
• simple code with lots of documentation
• allow me to replace SCSI HDDs in my legacy Macs with SD cards

What it's not:

• complete SCSI solution
• super-fast
• feature rich

Development Target

Using the NUCLEO-F401RE board, based around the STM32F401RE. This will be fine for development, but is an expensive micro. The STM32F401RCT6 is almost as capable and quite a bit cheaper (~$1.80 USD).

Other projects

If you need a solution today there are a couple of great options:

• SCSI2SD - http://www.codesrc.com/mediawiki/index.php/SCSI2SD

  Feature filled, high-speed and readily available.

• RaSCSI - http://www.geocities.jp/kugimoto0715/rascsi/

  Original built for X68000 machines, this one is based on the Raspberry PI as the host. Looks like it supports Target and Initiator modes.
