Over the years I've upgraded my Mac 512, first by getting the 128K
ROMs and then by adding a Dove memory upgrade.  As a result, I now
have a 2Mb 512Ke.  I received System 6.0 a few days ago and I am
very disappointed to discover that it doesn't work on my machine.
Any attempt to touch the serial ports causes a crash, and although
it installs the Sound Manager, the SystemBeep is always "Simple Beep",
even when I've selected something else using the control panel.

The same floppy runs fine on a Mac+ at work.  My guess is that
some of the patched-in code depends upon the small amount of hardware
that differentiates a Mac+ from a Mac 512Ke (e.g. the larger parameter
RAM).

I'd appreciate any suggestions for a workaround.
