We hate 2020!

Just when we thought 2020 couldn't get any worse! We were about to re-open after many months of being closed but then disaster struck when a mains water pipe burst and flooded much of the ground floor of the museum.
Sadly re-opening has now been postponed. Read More >>>

Zenith MasterSport 386SL

This Zenith Data Systems laptop uses Intel's 20MHz 80386SL processor and comes with 2MB fixed RAM, upgradable to 8MB. The hard disk has a 60MB capacity. The screen, although monochrome, is VGA resolution.

The SL-variant of the 386 is designed to be used in portable computers and features low power usage, integrated cache and memory controllers, an AT-bus controller, and EMS 4.0 hardware. It is also the first of Intel's x86 range to incorporate System Management Mode (SMM) which allows system-level software (such as power management systems) to take control of the processor at any time, regardless of the processor's current operating mode. Later PC's would also use SMM to emulate the PS/2 keyboard interface, allowing USB keyboards to be used even with operating systems that were not designed to support them.

Manufacturer: Zenith Data Systems
Date: 1992
