   No I don't mind, although there is a commercial copyright in it. 
   IE: free for personal use, copyrighted for commercial use.

   The unit is pretty much already all assembler, at least all the 
   OS detection code is.

   Any competent programmer could read the pascal code for getting 
   the OS/2 FP version and setting the correct timeslice drop code, 
   and convert it as needed.
