Has anyone copied the firmware out of the 8051 on the PRO RX50 controller? I'd like to have a look at it and see how hard it would be to add format capability.

In the Soviet clone Elektronika-85, both formatting and support for the second side were added.

Interesting. I wonder if the cloning is similar enough that its code would be useful for this project. Are you aware of any sites that would have information about the Elektronika-85's diskette controller? If it uses an 8051 and an FDC1793, I may be able to use its code. That would be a sort of Zen justice....
 
Electronicа-85 was made in Voronezh, they made one-on-one clones there, so they used (originally) 8051 in it, and then its Soviet clone. I will try to find out about firmware with formatting function and firmware with support for two sides - with a good degree of probability they have been readed.
 
I found a firmware, guaranteed with the function of formatting and working with two sides. I'm trying to clarify - with what program the floppy disks were formatted.
 
Checking to see how this is going, I have an extra floppy controller with a bad 8051 myself....
