I only have one Apple II disk in my collection, which is AppleWorks 2.0 (1987 edition). [...] Besides the one Apple II disk, I have the owner's manual for the 5.25" external floppy. That's about it.
Ah, you need more than a disk... you need an Apple II and a disk drive.
(he said he also had a Lisa, but he cannot find it. :?: )
Wouldn't that be fun?
I saw the disk images on Apple3.org (a great website, BTW). How would I go about transferring the disk image from a June 2010 MacBook Pro to a 1980 Apple III? I doubt I still have blank 5.25" disks lying around.
Well, you would need to find or buy some Single or Double Sided/Double Density (DS/DD) not High Density (HD) floppies. Then, with a serial cable in hand, you can bootstrap the
III and transfer disk transfer software to it, then transfer more disks. The process is outlined here:
