My sincere thanks to those who answered my question on the transfer of
graphic files between PC and Macs. Generated from everybody's answer,
there are several ways to do this:

1) Use Apple File Exchange or MacLink to transfer from or to Mac
2) upload from one platform to VMS or UNIX then download to another 
   platform
3) direct copy to and from Mac using DOS Mounter or AccessPC
4) direct copy between Mac and PC if you have Novell network since
   two platforms can access the same hard disk

Three formats are best for this purpose: GIF, EPS, TIF. 
Below are responses I received.

I work on both platforms.  In a addition I was a beta (and alpha) tester for
the new release of Adobe Illustrator v4 for Windows.  They jumped the number
to 4 to placate the PC people whom they had been neglecting. My experience is 
that several PC applications have trouble with eps because it is not that 
common a format on the PC side as some others.  This is particularly true if 
you are saving your eps files in anything but Illustrator v1.1 format.  

Illustrator formats later than 1.1 will NOT be recognized because these later 
formats were not released on the PC until this May.  No one has had time to 
update their applications to recognize these versions yet.  If you wish to 
save an Illustrator file from the Mac as eps for use on a PC:

	1.   Name the file filename.eps (whatever name you choose but with
             the .eps file extension ...you likely know this first step)
	     Be certain not to exceed 8 characters for the file name.

	2.   Select eps format and v1.1 (NOT illustrator 88 or 3)

	3.   If you select to include the IBM compatible preview (which is
	     an embedded TIFF file) be aware that some applications have
	     trouble with how Adobe constructs such a file.  Its ok to 
	     skip this step.  You won't see a nice screen view in WordPerfect
	     but you should get a box with an X through it when you place the
	     image ...this shows the image size taken by the illustration.

Regarding TIFF files, there are a zillion versions of them.  The standard ones
are uncompressed or implement LZW, pack-bits or some other compression scheme
which is standard.  TIFF comes in so many flavors I dare not say much more for
fear that I will be contradicted by at least some of them.  The keepers of
the TIFF format (the putative standards police) are Aldus and Microsoft.  Its
best you contact them for the best info.  A good coversion utility on the PC
side is Hijaak PS for DOS or Hijaak for Windows, published by Inline Systems.
I use both the DOS and Windows versions on my PC.  However they are not cheap.
Either lists for $249.  The documentation in the DOS version includes some
fantastic info on most common PC and Mac graphics formats.  Either the DOS or
Windows versions recognize Mac formats of TIFF and will convert them to any
particular targeted PC TIFF format.  If Hijaak does not know that TIFF format
yet, present it with a file already in that version of TIFF and it will analyze
the monster and establish a new conversion template for that version.

To put a TIFF file into a format a Unix box can upload you will need to 
UUENCODE the file.  I don't believe you can load it directly (i.e. it is not
an ASCII text file the way a postscript file is).  There are utilities avail-
able for either the Mac or the PC to do this.  One problem though; I am unaware
of any Unix applications which can use such an encoded TIFF file.  The most 
you could do is FTP it to an archive site for others to download and use on 
their Macs or PCs.

Finally, if you are going to do much of this sort of thing I suggest you get
AccessPC or DOS Mounter.  Both of these inits do much better jobs of writing
to MS-DOS formatted disks than Apple File Exchange.  They are reliable, which
AFE is not, and will mount the disk directly on your desktop like a Mac disk.
They also allow direct copying of Mac files to a PC disk as if it were a Mac
formatted disk ...just drag and drop.

I think you should use the binary setting of FTP if you want it to work 
properly.  Try using a different translator in AFE (like MacBinary to 
Binary) also, and see if that works.  Finally, if you are SAVING them as IBM 
Format files, just try running DOS Mounter on your machine, and copy the 
files WITHOUT a conversion program onto the disk and then take it to the PC.

I hope this helps.

Use FTP to transfer the TIFF files from the Mac to the UNIX machine, and
use 'binary' mode, and it will work fine.  We do it all the time here.
Don't have any experience going UNIX --> PC, but imagine a binary file 
transfer would work as well.  EPS files are usually all ASCII, so 'ascii' 
transfer mode should work.  Try 'binary' mode if not.

If you transfer from the UNIX to Mac, remember to set the type and creator
of the TIFF file or applications won't recognize it as a TIFF file
(type == TIFF, creator == 8BIM).

Both files will be binary in nature. The only case where the eps 
file won't be binary is when you selected no preview in Illustrator

The Apple file exchange should have worked if you used the "default translation"
which is just a binary copy. One thing is the naming. the EPS file
should have a name in 8.3 format with the .3 as eps and the tif in 8.3 as 
tif. (This is not mandatory and some programs just check the first
few bytes of the file to determine the format but I highly recommend it.
It is magic in MANY programs!)

Normally, when you do uploading/downloading, it is best to set it to
binary, so that when a binary file is transferred, the file would not
screw up.  So, if you upload (using binary mode) from Mac to Unix, then
download from Unix to PC (using binary mode), the trasfer should be 
alright.  Note that binary mode can also be used to transfer text.

Hope this helps.
