Notes The ZX-Spectrum +2A and +2B are identical externally, but internally are different. The +2B includes in the motherboard the controller of the floppy disk drive, just like the +3.
The +2A use a motherboard "issue 2" while the +2B use a "issue 4".
The +2B is basically a ZX-Spectrum +3 with tape-cassette recorder instead the 3" floppy. The +2B is the last of the Spectrum's.
