Medley supports both Interlisp and Common Lisp. The system starts up with a single Exec window running a
read-eval-print loop (REPL) for executing Lisp. This Exec window can be either Interlisp- or Common Lisp-based.

Additional Exec windows based on either Interlisp or Common Lisp can be started at any time from the background menu.

Any custom Notefiles that you created on the "old" notecards.online,
will need to be moved manually. Please contact email@example.com for help.
