 As sysvars is optimized for speed, being compact and system friendly, it is not an elaborate H/W detection tool, such as WhichAmiga. This means that there might be system combinations, where sysvars gets it wrong. Some known limititaions are listed below. Anyway, you can always file a bug report, if you think that sysvars can be optimized.
 
 ## Kickstart 1.3 and below
-- Sysvars currently detects CPUs above 68020 as 68020 and any FPUs as 68881.
 - Environment variables can only have global scope (i.e., they reside in ENV:). This means you must have ENV: mounted (e.g., to some folder on RAM:). This is not required for OS 2.0 and above.
 - Environment variables can only be used with the IF command (things like
   ``ECHO $CPU`` do not work. You must use ``IF $CPU GE 68010``).

 The tool is already quite useable, but there are still some things missing, which I want to fix in future versions (no particular order):
 
 - Add ``$RTG`` variable to enable/disable stuff like FBlit or swap screen mode configurations
-- For Os 1.3: add detection for CPUs > 68020 and at least the 68882

 - Make use of boards.library and identify.library if available for even more expansions.
 - Make a WinUAE/FS-UAE-based test suite for automated tests (CI/CD-like)
