     First, it may help to know that that the programs which create
images need to work with diskettes which are not copy-protected. This is
no barrier for your own programs; it will be a problem for most
commercial games.

     One thing you can do is deprotect your game diskettes. This
requires information specific to the game and, sometimes, the particular
release. You can find deprotect info in places like issues of Computist
magazine.

     Usually, a better strategem is to check out the disk images on
Asimov and Uni-kl.de. URLs are ...

Asimov- #1 archive of Apple II games and utilities in
  emulator DSK and file formats; plus emulators and emu info 
  ftp://ftp.apple.asimov.net/pub/apple_II/

Asimov Mirrors- sites which mirror Asimov
  ftp://apple.cabi.net/pub/apple_II/
  ftp://mirror.aarnet.edu.au/pub/apple_II/
  ftp://mirror.apple.asimov.net/pub/apple_II/

Asimov-GS- major archive of IIgs software
  ftp://apple.cabi.net/pub/applegs/

Uni-kl.de Apple2 U. Kaiserslautern- II/IIgs games, utilities, and
  emulator wares
  ftp://ftp.uni-kl.de/pub/apple2/


     Most disk image (.dsk) files are stored in compressed .gz form. On
your PC, the first step for a .gz file is to uncompress it using WinZip.
This should produce a 143,360 byte length .dsk file for most 5.25"
diskettes.

     A .dsk file can be used as a virtual disk for emulators like
AppleWin on the PC. To get it into a form usable on your Apple II, the
.dsk file must be transferred to the Apple II and converted to regular
diskette form.

     The usual way to transfer files from PC to Apple II is via NULL
modem.

004- How do I transfer files between computers using NULL modem?

     You will need a NULL modem connector and each computer needs a
modem cable and telecom program.  A IIe or II+ will also need a serial
card.

  ____________                                        ____________ 
 |  PC or Mac |                                      |  Apple II  |
 |  running a |                                      |  running a |
 |  telecom   | <--modem--> [NULL modem] <--modem--> |  telecom   |
 |  program   |    cable    [connector ]    cable    |  program   |
 |____________|                                      |____________|


    "NULL modem" means "no modem". A NULL modem connector is just a pair
of connectors wired 'back to back' with a few lines switched so that
each computer views the other pretty much as though it were a modem.
NULL modem connectors can be found at Radio Shack for a few dollars or
you can make your own. 

     On the Apple II side, you can choose from several good telecom
programs. Since you would like to be able to do z-modem transfers, good
choices include Intrec's ProTerm-A2 3.1 (Enhanced IIe -- IIgs), MGR
Software's Modem MGR (II+ -- IIgs), AnsiTerm (IIgs), and Spectrum
(IIgs).  You can also choose from many freeware and shareware programs.
Generally, these support x-modem but do not support z-modem. 

     If you're running under a current version of Windows, HyperTerm
works very nicely on the PC side. (For sending Text files from PC to
Apple under HT, be sure to uncheck "send line enders" in the ASCII
settings.)  If there is a choice of terminal emulations, it seems best
to stick with something simple, such as "TTY". A good NULL modemming
program for running under DOS is Telemate, commonly available as
shareware. Many other telecom programs are available and work fine under
current Windows, old Windows, and DOS. Similarly, there is a good
selection of Mac telecom wares.  

     To do transfers, you just connect the modem cable from each machine
to the NULL modem connector. If your PC or Mac has a spare COM port, the
connection can remain in place without disrupting normal net connections
through the other COM port. For a GS, the modem  cable should be a "high
speed" type which allows hardware handshaking and this option should be
set in the GS telecom software. The same is true for other Apple II's
running at 9600 baud or above.

     Set the same format (8-N-1) and baud rate on each telecom program.
(The format will, almost always, already be set to 8 bits-No parity-1
Stop bit.)  A good first-try speed setting is 9600 baud. If errors
indicate this is too fast for either machine, you can move down to 2400
baud. An accelerated GS running Spectrum can connect with modern PC's
running HyperTerm at 56k baud or better.

Note: Spectrum (and most other newer Apple II telecom programs) do not
require that you modify Control Panel settings for speed and
handshaking. Since Spectrum directly accesses the GS serial port, speed,
etc. settings are done in the program. (By the way, this frees-up Slot 2
-- the GS modem firmware Slot-- for any peripheral card which needs to
have its Slot set to "Your Card" in the Control Panel.)

     Place each program in terminal mode-- often, this is the default
mode. Or, the particular telecom program may have menu items or buttons
you select for specific kinds of transfers.

     Next, you will usually select the function (send or receive) on
each machine and the protocol. The protocol should be the same on both
machines. Z-modem is the best choice for most single or multiple file
transfers. Text files can be an exception (see the next question). A
plain ASCII transfer will circumvent most problems but is slower; and,
you may need to send and receive/capture files one-by-one instead of in
batches.

     Finally, you will select the file or files to send or "Open".

     Usually, it is best to start Receive on the target machine before
starting Send on the source machine. If you find that one telecom
program or the other does not give you enough time to start Send-- i.e.
it keeps "timing out"-- change the program's "Time Out",  "Inactivity
Delay", etc. setting.


Note: Some telecom programs may expect an end-of-send signal which the
sending program does not supply.  Pressing CTRL-X or RETURN on the Apple
II or ESC on the PC often seems to work okay for terminating the Send.

From: Jeff Blakeney

     You don't need to manually tell Spectrum or other modern telecom
programs to receive a file each time you do a Z-modem transfer. Just
make sure that you have Auto Receives turned ON. In Spectrum the setting
is in the Settings/File Transfer/Receive Options... dialog.

     A good way to convert .dsk files to diskette form is to use a
program named "DSK2FILE". It is available on most A2 archive sites. You
can download it from ...

 DSK2FILE (recommend version 4.3 or later) at ...
  http://keaggy.intmed.mcw.edu/dsk2file.html
  ftp://ground.ecn.uiowa.edu/apple2/Emulators/
  ftp://ground.ecn.uiowa.edu/2/apple2/apple8/Utils/
  ftp://ftp.apple.asimov.net/pub/apple_II/utility/

On a 128k Apple II (like a IIc) DSK2FILE can create diskettes from .dsk
image files; and, it can create .dsk image files from diskettes which
are not copy protected. Like most Apple II software, DSK2FILE will be in
.shk ("ShrinkIt") from when downloaded. This saves a lot of space on
archive sites. To uncompress a typical .shk file, you can use regular
8-bit ShrinkIt. You can find ShrinkIt at ...

ftp://ground.ecn.uiowa.edu/2/apple2/useful.stuff .


So, once you have the basic software and NULL modem connector, the usual
procedure for getting a disk image from Asimov or Uni_kl.de to diskette
form on your IIc is ...


1. Download the .dsk.gz file from an ftp site (like Asimov)

2. On the PC, use WinZip to uncompress a .gz file to plain .dsk form.

3. Use a NULL modem connection to transfer the .dsk file from the PC to
your Apple II.

4. On your Apple II, use DSK2FILE to convert the .dsk file to diskette
form.
Note: the target diskette must be formatted. Usually, it should be
formatted for DOS 3.3. It is okay to use the DOS 3.3 INIT command to
format the target diskette; or, you can use Copy II Plus to do a plain
format.


     A similar procedure in reverse will work for converting
non-copy-protected diskettes to .dsk files and getting them to your PC
for use with an emulator such as AppleWin ...

1. Use DSK2FILE to convert the diskette to a .dsk file.

2. Use a NULL modem connection to transfer the .dsk file from your Apple
II to PC.
