What is BlueSCSI?

BlueSCSI uses a Blue Pill (STM32) to appears as one or several SCSI hard drives to your vintage computer. You can use it to replace existing (and probably dying) SCSI drives, or as additional drives in your machine.

It stores its data on a microSD card readable by any Mac, Windows or Linux machine. This makes exchanging data with the modern world a breeze. Up to 7 drives can be set up on one microSD card.

Models

There are 2 models of BlueSCSI:

Desktop

An internal BlueSCSI that connects to the existing 50-pin SCSI cable inside your machine.

DB-25

An external BlueSCSI that connects to the SCSI port on the back of your machine.

	Desktop	DB-25
Storage	microSD card (not provided)	microSD card (not provided)
SCSI Termination	Enabled and disabled via jumpers on the board	Always active
Power*	Provided by the SCSI cable	Provided by the SCSI port
LED	Activity and Power LEDs can be connected	None

*If the machine doesn’t supply Termination Power (Mac Plus or Mac IIsi for example), the USB port on BlueSCSI can be used to provide an external power source. In addition, the Desktop version features a Berg connector that can be used for that purpose. See this page for compatibility information.

All the technical details are available on the official page for the project on GitHub.

Versions

We offer three versions of each model:

Fully Assembled

Set up your microSD card (not provided), connect your BlueSCSI to your computer and you’re done. Every assembled BlueSCSI is tested on actual hardware (a Macintosh IIci) before shipment. In the unlikely event your fully assembled BlueSCSI is not functional upon arrival, you have a 14 days window to return it and we’ll refund you.

Kit with Soldered microSD Card Slot

Everything you need to assemble your own, without the hassle of dealing with the slightly tricky mounting of the microSD Card slot. All soldering is done through-hole, so this is a great one to get if you have a little bit of soldering practice and want a fun and easy project to work on. The Desktop version comes with two 330 Ω resistors that protect the external LEDs. For a brighter light, you may use 220 Ω resistors instead but, considering the age of the LEDs you will probably be powering, we don’t recommend it.

Kit with Unsoldered microSD Card Slot

As above, but you’ll have to solder the microSD Card slot yourself.

In all cases, we are selling revision 1.1-a of BlueSCSI. The Blue Pill STM32 comes flashed with the latest firmware.

We ship for free from Belgium to all countries of the European Union via regular mail, generally within a week of your order, sometimes less. The padded envelope contains your order and instructions.

We do not offer returns on the kits.
