+2A not OK

Although the only noticable outward  difference  to its older brother,
the +2, is that the new +2A  sports  a swanky new black look. Open her
up though a you will find the insides have been redesigned to resemble
the +3. One advantage of this is the provision of a Centronics printer
port. However one of the worst  features  is the failure to modify the
expansion port. This  renders  really  useful peripherals inoperative.
add-ons like  the  spec-Drum,  Plus  D  interface  and  the  range  of
Multifaces quite simply won't work.  Software  compatibility is also a
bit of a minefield with many titles not working.
