The DCPU-16 is a 16-bit microcomputer that was popular in 1988. It is unknown when the computer was initially released, nor is it known by whom. The player will have one (or more) DCPU-16s on board their ship.
The DCPU-16 is emulated in 0x10c. It is still under development (although Notch mentioned almost being done[1]). The current version of the DCPU-16 is 1.7.

[edit] 3rd Party specification
Several people besides Notch have made suggested extensions to the DCPU-16. These are not recognized officially by Mojang or by Notch, and Notch has discouraged fans of 0x10^c from contributing additional specifications for now.
