AT-SLOW
(ver 4.10)
Shareware made Abandoned Freeware


AT-SLOW is a slowdown TSR for playing old games and adding an 
Exit to DOS for programs that don't allow it.  This registered 
Freeware version contains several enhancements and additions that 
were not available in the previous shareware versions.

AT-SLOW uses the AT's (286 and above) real time clock found at 
interrupt 70h to slowdown software speed.  Using the real time 
clock's interrupt has two advantages over the usual use of the 
normal PC's timer:
   
  1 - The high resolution timer can occur up to 8192 times a second
      (as opposed to 18.2 with the normal timer). This provides a 
      much smoother slowdown than with the normal timer. This also 
      provides a higher degree of performance reduction.

  2 - Since this slowdown uses interrupt 70h, and only AT's actually 
      used this interrupt, programs don't know to re-vector it. So
      programs that don't work with normal slowdown programs 
      should work with AT-SLOW.
