Version 4.06 fixes some system exclusive bugs and adds a few features.
You can download it here
Unzip the file, and put the two .bin files on the root level of a USB drive. Boot the DSS-1 into test mode holding the DATA A up/down buttons until you are asked to upgrade the OS. You may have to disconnect the USB device in the other port in order for the upgrade to be recognized.
Change list is included in the .zip file
Huge thanks to Jim Babb for continuing to support and enhance the DSS-1 after almost 35 years. For those of you who don’t know, Jim is the creator and programmer of the upgrade from 1987 along with Paul Kreter.
Thank you so much for this site! I was thinking it was time to part with my DSS-1 since it has not been working for a few years drive works but will not download info into drive? do you know anything about these floppy drives?
Awesome Tom. Thanks for doing this update.
A note: after updating to this OS, my default system (on the USB A internal drive) is not loading automatically. Upon starting my DSS-1, it just goes to the SYSTEM screen. Any way to fix that?
Also, I was hoping for an auto-loop selection fix. Is that in the works at all?
Still love this thing!
