STSC's APL*PLUS for the Macintosh (formerly sold as PortAPL) has a built-in
APL terminal emulator for an APL workstation. In addition to having an APL
terminal emulator built-in, APL*PLUS, a comprehensive APL system in its own
right, also includes a LaserWriter APL font which can be used for printing
documents with APL characters in them.
There is also a version that runs on the Macintosh SE.
