That's right, unless you boot from a system disk, no dice. Older Apples
had built-in firmware for saving to audio cassette tape, but this one
doesn't. And booting from disk will erase any BASIC program in memory at
that time. So unless you FIRST boot from disk and THEN type in your
program, forget about saving it.

One more thing: The physical floppy disk format of your computer is the
same as that used by Macs for 400K and 800K disks. However the files are
structured in a different way. That means that normal Mac 400K MFS and
800K HFS floppies are still unreadable and unwritable in your //c+. On
the other hand, all old Macs, with operating systems System 7 through
Mac OS 9.2.2, and with a built-in floppy drive, would be able to read
and write "ProDOS" disks for your computer; you can select "ProDOS" when
formatting a floppy on these computers.

That can be a roundabout route to "sneaker-net" software to your new
//c+ if you don't get ADTPro to work - you can e.g. put a DiskCopy disk
image on a PC formatted 1.44MB disk on the PC, then write the image to
an 800K disk on the Mac which would then be bootable on the Apple //c+.
But generally ADTPro is far more convenient.
