     The best way to transfer files from PC or Mac is via a NULL modem
connection. You have a telecom terminal program, like Spectrum, running
on the GS and a telecom terminal program, like Hyperterm, running on the
PC. You set baud rate the same on each, connect a modem cable from each
to a NULL modem connector, and send your .DSK (or .SHK, etc.) files via
Z-modem from the PC to the GS.

     Once on the GS, you can convert .DSK files to diskette using
DSK2FILE or ASIMOV. (Make sure the 5.25" diskettes you use are
formatted.)

Note: Most of the files you download from Asimov will be .DSK files
which have been compressed to .gz files. (The file name will end with
".gz".)  You can uncompress .gz-compressed .DSK files on your PC using
WinZip to obtain genuine .DSK image files. 


     If you do not have a telecom program on your GS, then, ADT could be
useful as a 'getting started' step-- i.e. you could use it to transfer a
disk image of a telecom utilities disk from PC to Apple II.

     Assuming the downloaded copy of ADT is okay, the big problem is
likely to be getting PC to send the ADT DMP file to your Apple without
inserting characters. For example, using Hyperterm on the PC you would
want to make sure that, in the ASCII Settings, "Send line enders" is not
checked.

     A check that the transfer went well is to go to the monitor and
look at the beginning and end of the file:


0803:4C 0E 08 05 00
0808:01 05 01 00 00 00 D8 20
...
1208:60 01 00 01 EF D8 00 00
1210:00 00 00 00 00 00 00


If the beginning looks okay but the stuff at $1208-$1216 is different--
like, the 60 01 00 01 EF D8 ... ends up at $1268 ...--, then, your PC
telecom program is likely to be sending extra characters.

     For sure, the ADT directions are not as clear as they could be.
Getting ADT going may take some experimentation.

     In case you are interested in 'getting started' alternatives to ADT
for transferring Apple2 programs and/or disk image files, below are some
excerpts from the new Csa2 FAQs:
