Zenith Supersport 286

ZWL-200-02, 20 MB HDD
ZWL-200-04, 40 MB HDD

This manual describes the SupersPort 286 Portable Computer, an 80286 based computer. The SupersPort 286 Portable Computer and the SupersPort Portable Computer, an 8088 based computer, appear almost identical except for the keyboard and LEDs. Be sure that the unit you are working on is the SupersPort 286.

The SupersPort 286 Portable Computer is a fully PC-compatible computer. It offers full computing capabilities in a small, lightweight package. In performance and power it most closely resembles the Z-286 computer with some obvious differences. The video system uses an advanced LCD controller rather than the more common 6845 controller. It also uses the low-power 8OC286 microprocessor and cannot accept expansion cards. Some of its other features are:

* A 25-row, 80-column liquid crystal display with a pixel resolution of 640 x 400. This display uses a double twisted-phneumatic LCD display with an advanced video controller.

* A 79-key keyboard that maintains full PC-compatibility with the standard 84-key keyboard and the 101-key advanced keyboard by using mode switching and multiple keys to duplicate the keypad and special function key operation.

* A keypad interface connector (5-pin DIN). The optional external keypad accessory provides the functionality of the 101 -key advanced keyboard.

* RGB video output from a 9-pin connector on the rear panel of the computer.

* One serial communications port (DB-9) and one parallel port (DB-25).

* An external floppy disk drive/tape backup connector (DB-25).
