Title: SCSI HDD Replacement
Post by: pshoey on April 25, 2025, 08:00:36 AM
Modern tech comes to our antique machines!!

Now it is possible to replace the SCSI drive with a new board that emulates SCSI devices from an SD card.

ZuluSCSI is able to do just that. It is an open source project.

Copy an image of the drive to an SD card and the Odyssey just boots up as normal.

Here is the link to buy the board: https://shop.rabbitholecomputing.com/products/zuluscsi-blaster

I am not connected to the project at all, just a happy user.

edit: added pic of the board in an Odyssey

Here is the final product. Installed using a 2.5 to 3.5 hdd adapter installed in the original hdd sledge.

Exciting news!  Just to confirm, the odyssey does boot up properly with this device?  Previous attempts at using other drives have not been successful because they were incapable of passing security checks at boot.

Yes, simply copy the complete 4GB SCSI disk image to a file, copy that to the SD card and name it as HD0.img and set the file to read only.

I don't have an Odyssey but am curious about the method to copy the hard drive image.

On a PC I typically have to use Rufus or Acronis to copy a hard drive image and in doing so I have booted off of the software so the drive is not active (ie no open swap files etc)... alternatively I would slave this to my PC using a USB adapter.

I certainly applaud this innovation.....

I wrote my own disk image utility to create a raw sector by sector dump of the drive - all the commercial image tools have their own formats and I didn't want to get locked into having to use one of them.
