Speedometer lets you measure the CPU and Disk performance of your old
Macintosh.

Download contains both Speedometer 2.5 and the very first version,
too, named MacSpeed 1.0. A bonus little fun (and annoying) app named
Radar Command is also included ? don't worry, it's harmless.

DL#1 is a StuffIt 1.5.1 archive. DL#2 is a DSK image of the same,
which is Mini vMac friendly.

Compatibility
Architecture: 68k

Maximum requirements: Mac OS 9.2.2, OS X Classic mode untested.

Minimum requirements: Seems to require a Mac Plus with System 6.
(MacSpeed 1.0 mentions the base speed is relative to that of a Mac SE
with 20MB SCSI HDD. Copyright date is from 1989. Speedometer 2.5's
Manual mentions the Mac Xl also works, but no mention of the 512K,
512Ke or 128K machines.)

On a Mac512 with 64K ROMs and internal HyperDrive 10, I would get
repeated ID=02 System Bombs when trying to launch any of the apps.
Even in Mini vMac, if you run System 3.x & Finder 5.x, you may see a
missing menubar and the inability to return to the Finder. It would be
nice if the author had specified minimum system requirements.
