BlueSCSI & ArdSCSino are hardware that reproduces SCSI devices (hard disks) with an Arduino STM32F103C (aka Blue Pill.)
BlueSCSI created by erichelgeson is a fork of
ArdSCSino-stm32 which adds:
Mac specific functionality
Enable/Disable Passive SCSI termination
An alternative power source if not able to be powered by the SCSI bus
Open Hardware (KiCad & Gerbers)
ArdSCSino-stm32 created by ztto is the STM32 version of
ArdSCSino created by Tambo (TNB Seisakusho)

If your computer is not listed below - it may be compatible but there is no guarantee it will work. This device is designed and tested to work with pre-PowerPC Macs.
To enable termination place the two jumpers on the TERM block. Termination should be enabled if it is the last device in the SCSI chain, otherwise remove the jumpers if it is not.
Older Version Specific Troubleshooting
Blinky! There are now resistors and pin outs for Power and Activity LED’s
Resistor nets flipped all the same way
50 pin allows for right angle connector
SD Card facing out the back - gives some better options for mounting and access
New bracket that uses less filament and has mounting options for most cases
Better mounting holes on the PCB
New artwork by @Stephen
Plugs directly into the DB25 port of your Mac.
Removed unnecessary components.
Termination is always on.
If you do not need termination you can socket or not install the resistor nets (this would be an unusual case)
Fixed issue with diode footprint being too small
Fixed issue with external power and
