Logitech MultiScope
MultiScope Debugger for OS/2

Logitech added an optional run-time debugger as an option to their system in late 1984. Previously it had been shipped with a source level debugger, much like the mouse system people were almost more interested in the run-time debugger for use with other development systems than with the Modula-2 system. After a couple of years the company introduced it as a separate product in the form of the Multiscope debugger. At the time the only other run-time debuggers available for the IBM PC were hardware based and thus expensive, the software based Multiscope therefore sold in large quantities.

The first prerelease was shown in 1989.
