El '''PDP-8''' ('''P'''rogrammed '''D'''ata '''P'''rocessor - 8) es un miniordenador de 12 bits creada por Digital Equipment Corporation ([[Digital Equipment Corporation|DEC]]) en abril de [[1965]]. Fue la primera [[minicomputadora]] comercialmente exitosa, con más de 50.000 unidades vendidas durante la vida útil del modelo. Su diseño básico seguía la estela del pionero [[LINC]] pero tiene un [[conjunto de instrucciones]] más pequeño, que a su vez es una versión ampliada del conjunto de instrucciones del [[PDP-5]].<ref name="pdp8-faq-pdp5">{{cite web|url=http://www.faqs.org/faqs/dec-faq/pdp8-models/section-1.html#b|title=PDP-8 Summary of Models and Options|at=Section - What is a PDP-5}}</ref> Máquinas similares de DEC son el [[PDP-12]], que es una versión modernizada de los conceptos PDP-8 y LINC, y el sistema de [[Sistema de control industrial|control industrial]] [[PDP-14]]. |

Hay otras [[Operador_lógico|operaciones lógicas]] que se conseguían implementar mediante [[macros]]. Por ejemplo para implementar una [[Disyunción lógica|OR]] el código sería el siguiente: |
|||
CMA // AC=not(AC) |
|||
DCA TMP // TMP= not(AC) |
|||
TAD M // Se realiza la suma entre el contenido de M y el AC |
|||
CMA // AC=not(AC) |
|||
AND TMP // AC= not(M) and not(TMP) |
|||
CMA // Se invierte el resultado |
|||
Otras operaciones que se implementaban mediante macros eran la resta, la [[Disyunción exclusiva|or exclusiva]] entre otras. |

Los lenguajes soportados por PDP-8 fueron el [[Basic]], Focal 71 y [[Fortran]] II/IV. |
