ID Amstrad NC-100
Short Name
Name NC-100
Company Amstrad
Description By 1992, once fast-growing Amstrad was struggling. Its reputation as a PC maker
had been undermined by a batch of dodgy Seagate disk drives at the same time
that bigger-name vendors were engaged in a price war, squeezing Amstrad out of
the market.
The NC 100, NC 150 and NC 200 were three products that its founder Alan Sugar was hoping would help revive the company's fortunes.
Cutting edge, they were not. Both were based on old eight-bit Zilog Z80
microprocessors. Curiously, both machines came with a BBC Basic interpreter on
which users could develop their own applications.
The NC 100 was a ?199 notebook computer the size of a piece of A4 paper, with a full size keyboard and a "letterbox" screen at the top, offering 80 columns by 8 lines.
It had an RS232 serial port and a Centronics parallel port for printer and communications. Built-in were 64 kilobytes of memory, expandable to 1 megabyte with the addition of an add-on memory card.
"If you can't use this new computer in five minutes, you'll get your money
back," boasted the company in its launch advertising. For ease of use, it had
four colour-coded keys giving instant access to a number of built-in
applications, including a word processor, calculator, diary and address book.
At a time when an entry-level lap-top computer cost more than ?2,000 and the
sub-notebook had not been invented, the NC100 and NC200 offered a good value
alternative for those with basic computing needs, such as word processing on the move.
All the NC computers were made in Japan by Nakajima. The company also sold its own version of the NC-100, called ES-210.
