The Z88 was built by Cambridge Computers, Sir Clive Sinclair's company after Sinclair Research was taken over by Amstrad. This laptop is testament to Sir Clive's brilliant mind and originality.
Powered by 4 AA cells, the Z88 is built around the Zilog Z80 CPU, clocked at 3.28 MHz; it's outfitted with 32K of RAM (expandable) and 128K of ROM.
The operating system and built-in software is contained in ROM, so applications do not require system memory to run; extra applications can be loaded through the 3 cartridge ports under the machine; more memory can also be added through the same ports. The display is a 640 X 64 monochrome LCD screen capable of displaying 104 columns X 8 lines of text; 3 shades of gray are also displayable.
