Emulate SCSI devices with an SD memory card.

We are Canada's authorized reseller of ZuluSCSI and SCSI2SD products.

2022.11.05: The new ZuluSCSI RP2040 now outperforms the older SCSI2SD v5 and v6 devices, and is compatible with more systems. We anticipate the manufacturer will discontinue the original SCSI2SD devices soon, if they have not already. Long live the ZuluSCSI!

Optional Floppy Power Header

ZuluSCSI runs off of bus termination power, supplied by your host computer.

Certain older machines do not supply bus termination power, such as certain Macintoshes.

If you know your machine does not provide terminator power, or are worried about compatibility, add this option to your ZuluSCSI order and we will solder this 4-pin power connector onto your unit before shipping.
