Thanks! I appreciate the comment.

Something I'd like to do is write up an article on what it takes to emulate an Apple 2. Getting the disk to work was surprisingly complicated--the Apple does all the low level track formatting in software which means the emulator has to take the logical disk image and generate a bitstream that the emulated software expects so it can turn it back into logical bytes in memory. That required getting a lot of details right about the bit format, rotation speed of the disk, etc.
