Yep, I am mostly reading. Rarely post. But I follow the Apple 2 boards very often.

Glad to know that he used his Apple II knowledge for creating an emulator later.

Yes, the article in the Computer Za Vas says the same.

I know later Boyan Mitov created controllers for 3 inch floppy disks with real time clocks, which for sure supported ProDOS, but I forgot to ask him about US-DOS. This was back in 1993.

I was excited that the Apple still had development back then, even looking for possibilities to transfer my Pravetz collection to the Amiga.

Version 2.0 of US-DOS would be cool, if it is still available somewhere.
