5.4 How do you transfer Apple files to/from other personal computers?
Normally, you cannot stick a 5.25" disk in a non-Apple II machine and
have it read it. This is because the disk writing formats are
different at a hardware level, and no software exists (or will exist)
to let a PC read an Apple II 5.25" drive. However, with rarer addon
hardware, you can bridge the gap. This has been an insolvable problem
for nearly 15 years; if it could be solved in software, such a thing
would exist.
That being said, here's a list of ways that do work:
5.5 How do I transfer DOS 3.3, Pascal, CP/M files?
Unless you have a null modem (see below) and a comm program for the OS
in question, you'll most likely have to use a real Apple II to
transfer the files to an OS that a lot more systems can read, such as
ProDOS.
The ProDOS system software, the DOS 3.3 FST (optional part of GS
System 6.0 and 6.0.1), and Copy ][+ can all read and convert files on
DOS 3.3 disks to ProDOS disks; all but the DOS 3.3 FST can write from
ProDOS to DOS 3.3 disks. All data files should translate fine, but any
program requiring a specific OS will probably not run under the wrong
OS.
For translating between ProDOS, CPM, Pascal and DOS 3.3, try the
program Chameleon. You have to use the 'force disk as ProDOS' option
to copy to/from your hard drive.

Once the file is on a ProDOS disk, you generally have a lot more
transfer options available.
5.6 How do I transfer files by [null] modem?
This is probably the most accessible option; it can be done by an
Apple and any other computer as long as both have serial ports,
cable(s) to go between them, and communications software on both
sides.
Modems allow you to transfer computer data over phone lines; a null
modem essentially yanks the middleman of a phone. Null modem cables
(which are identical to serial printer cables) are essentially a cable
which plugs into the serial port of two computers, and is wired such
that when one computer sends, the other receives, and vice versa. With
a communications program that supports file transfer on both ends, you
can send files from one side to the other. There are a few companies
selling null modem cables and the like; see the appropriate section of
this FAQ- 10.2 for their info.
For those who haven't picked a program to download with, here are the
better Apple II programs listed alphabetically; for other systems,
you'll have to find a comparable program. All of the non-commercial
programs are available from FTP sites. If you don't have a comm
program already, your best bet is to have someone mail you one on a
disk or buy ProTerm. (See resources).
