   I have obtained some %c-modem software from sources suggested here   
   (although which ones do what is not that clear) and plan to try those.   
   Thanks to those that offered suggestions.   
      
   If none of those work to expectations, I will write a solution   
   as I have burned enough time on this problem already.   
      
      
   One option I am considering is to write something that cuts nine sector   
   by 512 byte 250K rate MFM diskettes directly on the Model 4 which can be   
   read on a PC system by software there, and knows how to span large files   
   across multiple pieces of media.   
      
   Another would be to write a serial port file transfer.  It's not hard   
   assuming you have reasonable tools and access/control of the serial   
   UARTs on both ends.   
      
   I also noted recently that the floppy driver in FreeBSD claims it can be   
   configured to read/write 18x256 250K MFM floppies, so I might just write   
   a tool under UNIX that can read/write the LDOS/LS-DOS/TRSDOS-1.x diskette   
   formats directly.  Then all I will need is a very simple tool on the   
   Model 4 side to break the large files apart.  "cat" can put them back   
   together on the UNIX end.  I haven't played with this yet, but to   
   write something in "C" that can read a LDOS/LS-DOS filesystem should   
   take a quiet evening or two, most of which would be spent on research.   
   This is the most elegant solution, since it could preserve file   
   dates/times and other directory information.
