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.


There are 2 models of BlueSCSI:


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

An assembled desktop BlueSCSI


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

LEDActivity and Power LEDs can be connectedNone

*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.


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.

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 ฮฉ resistors that protect the external LEDs. For a brighter light, you may use 220 ฮฉ resistors instead but, considering the age of the LEDs you will probably be powering, we don’t recommend it.

Where can I learn more about BlueSCSI?

The official project page on GitHub has all the information you need on BlueSCSI.

Which firmware version of BlueSCSI do you install?

We always ship the latest version of the firmware. Currently, it’s version 20220411, with the USB bootloader. This means that you will be able to upgrade your BlueSCSI yourself in the future, using a USB cable and the instructions found here.

Does BlueSCSI work on my machine?

We successfully tested BlueSCSI on these machines:

Many more machines are supported, including some samplers and Amiga. The full list can be found right here.

If your country is not in these lists, take a look at the other BlueSCSI sellers. Chances are that someone will be able to help you.

How long does it take, and what do I get?

We ship generally within a week of your order, sometimes less. In most cases, it takes from 3 to 5 business days to arrive. The padded envelope contains your order and instructions.

What’s your return policy?

Every fully assembled BlueSCSI is tested on actual hardware (a Macintosh IIci) before shipment. It must be able to boot the machine fully and perform sustained read and write tests. 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.

We do not offer returns on the kits. But if you need help or pointers, get in touch.

How can I get in touch with you?

If you have any question or request, get in touch on Twitter or by e-mail: bluescsi at (all together). You can sometimes find me on the Discord server for BlueSCSI.

I’ve seen people sell BlueSCSI online but they’re not listed on the official sellers page. Can I trust them?


However, BlueSCSI is an open source and open hardware community project. By selling BlueSCSI without permission, these resellers go against the terms of the license. They choose to profit from the work and the active collaboration of the community, without contributing themselves.

The official sellers are all active members of the community and, by supporting them, you support the project as a whole.

What’s this “Disk Jockey” thing I’ve heard about?

Disk Jockey is a macOS application I wrote in my spare time to help you create blank disk images for your BlueSCSI (or any other device or emulator that works with disk images). It has its own page explaining it all.
