The codename for this adapter or video output capability on the Portable appears to have been "Topanga".

This expansion system allowed the Portable to be "docked" and connected to an external chassis containing two SE PDS slots.

It used a PDS card installed in the Portable to connect the Portable's PDS bus to the expansion chassis.

From BYTE magazine's November 1990 issue:

If you want to use a large-screen monochrome monitor with the Mac Portable, or connect the Portable to a mainframe computer system, you can use Second Wave's ExpanSE Home BaSE, a two-slot Mac SE card chassis.
The chassis serves as a base station for the Mac Portable, housing two standard Mac SE 68000 Processor Direct Slot cards. The Portable sits on top of and connects to the chassis through an included interface card and two cable assemblies.
Price: $995

In the December 1990 issue of MacWorld, a seller listed the price as $895.
