The Zenith MinisPort (styled as minisPORT) is a subnotebook based on an 80C88 CMOS CPU running at two software selectable speeds: 4.77 MHz or 8 MHz.

It was released in 1989 by Zenith Data Systems (ZDS).

It had 1 (model ZL-1) or 2 MB (model ZL-2) of RAM, ran MS-DOS 3.3 Plus from ROM, had a 640×200 LCD display and CGA and composite monochrome outputs.

The MinisPort was one of the first actual subnotebooks, apart from a contemporary NEC model.
