Following are some results of testing the SupraTurbo 28 with the benchmark
program AIBB5.0.  The machine used for testing was an Amiga 2000 with 4MB of 
FAST RAM (on a SupraRam 2000 card).  An Amiga 500 with some FAST RAM would get 
the same results.  Note that, just like any other accelerator, the SupraTurbo 
28 requires you to have some RAM in addition to CHIP RAM in order to see much 
acceleration at all.
  I left the comparison machine at the default which is an A500 with no FAST
RAM.  If you have AIBB and you can compare these results to the results
you see with the other comparison machines if you would like.  I only did the
non-floating-point tests.  The results for the Floating-point tests were
similar unless you had AIBB use code which was WRITTEN for a co-processor.
Programs which are written to take advantage of a math co-processor will of
course run much faster on machines which have a math co-processor (which the
SupraTurbo 28 does not).

     IMath                           3.08
 
     MemTest                         2.78 
 
     TGTest                          1.69 
 
  Note that the TGTest does not benefit much from acceleration.  Even an Amiga
3000 at 25 MHz only gets a rating of 2.28 on that test.
