I have a query out to the cited Apple folks and a number of others, and Steve here cited two more: *From: Steve Wozniak* Date: Wed, Feb 24, 2021 at 1:05 PM Subject: Re: Apple II DOS question Cc: Randy Wigginton, Andy Hertzfeld *All I can say is that this was a LONG time ago, before this practice which is common today. I never heard anyone complain about this form of copy protection. Our platform back then was a step lower, largely hardware, and our open source approach made it easy for others to understand and modify things.* I'll keep you all posted re: other replies.

Hi Laine,
When I was at Personal Software (subsequently VisiCorp), we had Apple boot disks. That was in the early '80s. Maybe some of the staff from that period can help you - - try Visi- people Dan Fylstra, Brad Templeton, Bob Frankston, Dan Bricklin and others. Most of them are easy to find but let me know if you have difficulty. Of course, Woz probably knows and Daniel Kottke as well.
Good luck,
Liza

Hi all,
Some of you may know, I've been spending my pandemic days chipping away at a software history of the Apple II (under contract with U of Chicago, hopefully forthcoming… 2023?). Anyway, I finally had a question that neither I nor my extended network of retro computing enthusiasts seems to be able to answer--and was wondering if anyone at SIGCIS might have some insight here.
I'm looking for any information available on when Apple began permitting publishers/developers to put DOS on the floppy disks of their own products, thus allowing programs to boot without need for a System Master. My understanding is that this development happened either with DOS 3.2 or DOS 3.3, but I can't actually verify when this occurred at all.
The reason this is coming up is because I'm currently working on a chapter focused on the disk copy program *Locksmith* and copy protection. Allowing developers to put DOS on their commercial disks would seem to be an extremely important development for creating increasingly sophisticated copy protection schemes. Since DOS controlled how data on a disk was read, all devs/publishers had to do to create an uncopyable disk was store the data to the disk in an unconventional format, and then ensure they modified the DOS on their disk to be able to read it. While the disk would run just fine, it couldn't be copied by the System Master COPY/COPYA subroutines, which assumed a standard organization for data on the disk. So while not intended to allow developers to enhance their copy protection schemes, that was certainly one of the knock on effects of allowing DOS on disk.
Cheers to anyone who followed any of that. If anyone has a sense of how this industry level transition came about, or is even just certain of which DOS version it can be attributed to, I'd be incredibly grateful.
