The +D (or Plus D) was a floppy disk and printer interface for the Sinclair ZX Spectrum home computer, developed as a successor to Miles Gordon Technology's earlier product, the DISCiPLE. It was designed to be smaller, cheaper, simpler and thus more reliable.It discarded a number of the less important features of the earlier product — the network and joystick ports, the inhibit button and the pass-through connector — and replaced its ancestor's plastic wedge-shaped design which fit under the Spectrum with a simple flat metal slab which protruded from the rear of the computer.

Don, from Latin dominus, is a Spanish (pron. ) and Portuguese (''Dom'', ) honorific title. It is usually used as a mark of high esteem for a distinguished Christian hidalgo or fidalgo; that is, a nobleman. In English "Don" is usually preceded by a definite article ("the").Its abbreviation, particularly in Portuguese, is "D." It is still used in reference to priests, like the French Dom. The treatment was reserved for those who had royal or some higher old noble ancestry, as well as some title bearers who had their title without needing but the King's confirmation instead of authorization, the so called titles de Juro e Herdade. In Brazil it was not used in reference to nobles, but was used to refer to royals (both to the monarch and to princes), and, in the ranks of the clergy, it is only used to refer to Bishops or other senior ecclesiastical hierachs.
