Y’all might also want to follow what Disk Blitz (creator of the AppleSauce disk imaging tool) has been saying and doing around the Nabu:


He’s gotten a good understanding of the on disk format and how the Nabu recognizes its disks.

Thanks for the post @ajacocks We've been discussing this in the "Bad disk Image" thread and @diskblitz posted there as well. It was just delayed because his post needed moderation. I think we can trust him :)

Good news. I got a set of boards from @Klyball and after building it, I have successfully booted NABU CP/M from my NABU disk drive. There is still some more testing required as @Klyball built in a 34 pin floppy connector so you don't need the NABU floppy drive but 360K floppy drives should work. That is why more testing is required.

Sorry for the green unreadable background but that's NABU CP/M and the reproduction card is sitting on a box because I forgot about the two standoffs needed :) I'll provide a better update hopefully tomorrow.

I don't speak Z80 (do speak 8086) but I absolutely need to make a COLOR command once I can use this ;p

Certainly NABU CP/M supports large floppies, and even hard drives. Well, I have different floppy controller that can do DSDD 1.2MB in my development and CABSERVE machines. I bet they're not much different from the consumer floppy controllers besides the actual interface to the cable. I actually have a few floppies in that format that I haven't analyzed yet. The development machines used the NABU 1600 Mass Storage Unit which had a 10MB hard drive, and DSDD floppy. We typically divided it into two 5 MB partitons (E and F). The boot drive had all the utilities and some of the common development files. F in different USER spaces held the different projects I was working on.

In theory a 720k will work if the software has the option for 80 track the controller supports DSDD and the side select line is utilized, I don't have a unit to test with yet

Woot maybe I can get one come new years... Hope there are some left. I had bills and xmas, plus trying to restore a car (Merkur Xr4ti), so was just wrong time when they popped up.
