Cambridge Z88

The image is clickable

1988.

This small and lightly built computer came as the name suggest 1988. Despite the fact that it came rather late - IBM and Intel would have been a few years now - it was based on CMOS Z80 processor. A computer that Sir Clive Sinclair - known for a number of other computers with the name Sinclair and which Amstrad a few years earlier purchased the names to - has constructed.

Cambridge Z88 was about as big as an A4 sheet of paper, a few centimeters thick and weighed only 900 grams. A small portfolio was even enclosed to carry the computer in. Despite the small size, there were many built-in programs in the expandable ROM (up to 3MB). Eg word processing, spreadsheet, database, diary, calendar, clock and a tool for the exchange of data with a PC. However, there were lack of a particulary programme, a type of editor in order to avoid having to rewrite the entire line in the event of any clerical error in programming.

Any type of tape or disk memory does not exist. However, the RAM was expandable up to 4 MB via expansion slot through the front. It can store all the data you need to save. This also means that you could run very long time in the four AA batteries that you could buy almost anywhere.

Is there any errors? e-mail and correct me!
