Computer published 38 years ago:
ZX Spectrum +2a (c) 1987 Amstrad PLC.
The ZX Spectrum +2a was a variant of the "Spectrum +3".
- TECHNICAL -
Housed a black version of the Spectrum +2 case mouldings.
The Spectrum +2a motherboard (AMSTRAD part number Z70830) was designed such that it could be assembled without the floppy disk controller or associated logic and a +2 style 'datacorder' connected.
The power supply of the ZX Spectrum +2A used the same pinout as the +3. However, the power supply purchased with the +2A had 'Sinclair +2' written on the case.
- TRIVIA -
Originally, Amstrad planned to introduce an additional disk interface for the +2A called the AMSTRAD SI-1, however this never appeared. If an external disk drive was added, the +2A on the system OS menu would change to a +3.
