Zenith model number ZWL-183-92, ZWL-183-93
The Z-183 Laptop computer is a portable, fully PC-compatible computer. It offers full computing capabilities in a small, lightweight package. In performance and power the Laptop computer most closely resembles the Z-158 computer with some obvious differences. The video system uses an advanced LCD controller rather than the more common 6845. The Laptop computer also uses the low-power 8OC88 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 200. This display uses a twisted-pneumatic LCD display with an advanced video controller.
A 78-key, full function PC-compatible keyboard that duplicates the functions of the standard 84-key PC keyboard. This keyboard uses severa[ operational modes to provide maximum PC compatibility
RGB and composite monochrome video outputs.
One serial communications port (DB-25) and one parallel port (DB-25).
A real-time clock.
A rechargeable Nicad battery (1.5 A/Hr rated) for portable operation.
One or two internal 720K, 3.5-inch floppy disk drives. An optional internal 10M or 20M, 3.5-
