And adding Microware's name to the copyright message...   LOL

Ah, ok.  I must have missed out on the Disk 1.0 ROM altogether.  I bought Level 1 in, I think, 1982 and I must have bought a newer controller too because I was booting OS9 from the get go with 'DOS'.  Although I do remember one of the first things I did to my original disk controller was to modify it with a 28-pin EPROM so perhaps I 'upgraded' to 1.1 without knowing it!
