The '''ZX Spectrum +2A''' was a variant of the Spectrum +3 housed a black version of the Spectrum +2 case mouldings. The Spectrum +2A/+3 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.<ref>''Spectrum +3 Service Manual''. AMSTRAD. p.18.</ref> Originally, Amstrad planned to introduce an additional disk interface for the +2A/+2B 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.
The power supply of the ZX Spectrum +2A used the same [[pinout]] as the +3. However, the power supply purchased with the +2A/B had "Sinclair +2" written on the case.
