That would be a quick and definitely dirty test but not a good one.
The files created by DriveWire4 when running as root will linger
around and cause new, interesting issues when later you run it as a
normal user. Which you should...

So if you do run it as root, better nuke the DriveWire4 folder
afterwards and start from scratch again.

And why you shouldn't run DriveWire4 as root? It gives for example
access to your whole computer file system from the CoCo or over TCP if
running Becker... Not that there is much malware on a CoCo, but bugs
in software might cause damage.
