   I'm using many DOS's with my I/III/4 TRS-80s, whatever is required by   
   the software. If it's TRSDOS 1.3 I just let it waste space using only   
   the first 40 tracks on side 0... With 3.5" It is actually not necessary   
   to use a "skip mode" or whatever, just letting it use the first 40   
   tracks makes it somewhat compatible between all DOS's, as it used to be.   
   With my own stuff, compilers etc. I use DOSPLUS or LDOS/LS-DOS. It is of   
   course then I need the space and 720K works nicely for most. It is often   
   the number of files that limit what I can have on one floppy...   
      
   CF, compact flash interface would be nice if it could be made to work   
   with LDOS/LS-DOS and DOSPLUS. Isn't it IDE interface? So, maybe it could   
   work with an IDE interface similar to the one by Larry Quinn/Larry   
   Campanell, where there at least is a driver for DOSPLUS.   
      
   Note 1: "skip mode" is what you need on a 5.25" 80 track drive to read a   
   stock 40 or 35 track media. My old 80 track 5.25" drives have a switch   
   that makes the drives do the "skip mode" automatically (40/80 track type).   
      
   Note 2: It was earlier mentioned about a special dual sided format that   
   saw each side as a separate drive. I used this. At first I used   
   Smal-LDOS 5.1.3, the shop where I bought this didn't know what I later   
   discovered, so they wired the EI to do it so that :0 had :2 on the back   
   and :1 had :3 on the back. What I later discovered was the I could have   
   run the the DD driver (even without a DD kit) and it would be able to do   
   real cylinder type dual sided (when I undid the mods), just not DD. I   
   always had a straight cable without any pulled pins.
