Once upon a time, a long time ago, there was a conflict between a now
very old version of MacsBug and the StartUpScreen INIT that keeps the
StartupScreen around all the time.

Any version of MacsBug since 5.3 should work fine, and no, there is not
a bug that I am aware of in the Mac Plus ROMs that is related to this
issue.  Ideally you should be using MacsBug 5.5, which works on the Mac
Plus, Mac SE, and Mac II, and with any RAM size from 512K to 4 MB (8 MB
on a Mac II).
