Thank you again for your work!!

Pity he does not feel our nostalgia and excitement to keep these beautiful machine running, and surely he missed some details (eg no microdrive for spectrum), but anyway here https://floppydays.libsyn.com/floppy-days-85-interview-with-john-grant-developer-of-zx80-os-basic you can find an interesting...
