The last Sinclair-branded computer to truly from the Sinclair stable, the Spectrum 128 debuted in Spain, thanks to co-development with Sinclair's Spanish distributor Investrónica, and did not launch in the UK until into the new year.

It also included additional interfaces, including an RS232 serial port, RGB monitor output, and a connector for a numeric keypad (which was available in Spain but never made it to the UK).

Although it retained the Sinclair name, the Spectrum +2 was a product from the Amstrad stable, following their purchase of Sinclair in 1986. As such, it is no coincidence that the design bears more than a passing resemblance to Amstrad's own CPC 464 system. A later variant, the Spectrum +3, con... (read more)Sinclair, 1986
An update to the Spectrum that essentially took the 48K model and added a QL-style keyboard, enabling the Spectrum to at least in part escape the criticism that was often leveled at the 'dead flesh' feel of the rubber-keyed version (although in actual fact the feel of the keyboard was still very ...
