     You can find a ProDOS 8 program selector Startup program which will give
you some idea of your speed on Uni-kl.de at ...

ftp://ftp.uni-kl.de/pub/apple2/gs/utils/launchers/ .

The file is SpeedGS.shk. (Use ShrinkIt or GS-ShrinkIt to uncompress the file on
your IIgs.)


     Besides showing date and time, SpeedGS gives speed in terms of a
multiplier for "Normal" IIgs speed (which is very close to 1MHz).  For example,
when our 10Mhz ZipGSx board is active and set at max, the SpeedGS display shows
Speed as "x10". Setting the board to 7Mhz gives a Speed of "x7"; and, going to
the Control Panel and setting Speed = Normal results in Speed showing as "x1".

     To get a better idea of small changes in speed, you can remove "INT" in
front of the parenthesis in, I think, Line 5. (The actual speed value may be
off a bit; but, you will gain an extra significant digit for making
comparisons.)
