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 >>>

Cambridge Z88 in prototype Optimus Case

The Cambridge Computer Z88 was an A4-size, lightweight, portable Z80-based computer with a built-in combined word processing/spreadsheet/database application called Pipedream, along with several other apps/utilities, such as a Z80-version of BBC BASIC.

The machine was designed by Sir Clive Sinclair and released by his company Cambridge Computer in 1987 (Sir Clive having been unable to market the computer as the Sinclair Z88 after selling Sinclair Research's computer business to Amstrad in 1986).

The Z88 is a portable computer based on a low-power CMOS version of the popular Z80 microprocessor. It comes with 32 KB of internal pseudo-static RAM and 128 KiB of ROM containing the Operating System (called OZ), but can be expanded up to 3.5 MB of RAM, of which the contents are preserved thanks to the batteries. An integrated capacitor prevents the Z88 from losing its data for a limited amount of time while changing the batteries.

This Z88 has a unique case which is a prototype designed by Optimus. This was kindly donated by Daniel Bangham from Wood, Wind & Reed of Cambridge.

Manufacturer: Cambridge Computers
Date: 1988
