как я понимаю стремиться надо к 1.04

     Rainbow TOS (TOS 1.04)
     -----------

     TOS 1.04 or Rainbow TOS, as it is commonly known is the latest
     version of TOS available for 520/1040/MEGA owners. It has been
     available as a dealer upgrade for awhile now. It has much more 
     robust Disk I/O, Autorunning of GEM programs at boot up, 
     a fix for the 40 folder limit, and much more. Most of all is 
     it much faster than previous versions of the Operating System.

       Formats:   2 chip ROMs (a 1MB Prom DIL-Chip), 6 chip ROMs (a 256KB Prom 
                  DIL-Chip-available as Upgrade!) 

      Machines:   Stacy

     Utilities:   TOS14FIX.PRG, POOLFIX3.PRG, CACHEXXX.PRG, FOLDRXXX.PRG 

                  TOS14FIX.PRG solves some small problems in the AES (for
                  additional information, please see the documentation that
                  accompanies the TOS14FIX.PRG program).
    
                  POOLFIX3.PRG fixes a bug in GEMDOS. Documentation that
                  accompanies the POOLFIX3.PRG program explains (in detail)
                  the problem that it fixes.

                  CACHEXXX.PRG is a new program that adds GEMDOS buffers
                  to your system. The caching of data and disk directories
                  by GEMDOS (when this program is used) will result in 
                  your system running much faster! This program is highly
                  recommended and requires TOS 1.04 or higher for full 
                  benefits!             

                  FOLDRXXX.PRG is explained above.


        Notes:   Please use the utilities available and if you haven't 
                 upgraded to this version of TOS yet.. please consider
                 doing so. It's a very worthwhile upgrade.

                 There are some disk-based versions of _early_ developer
                 only releases of TOS 1.04 floating around on BBS systems 
                 here in the United States and abroad. Please don't use 
                 them! They are bad news! They have some very nasty bugs 
                 and have been known to corrupt data!
