Discrete Logic
Before the advent of microprocessors, it was possible to build small scaled computers using small-scale integrated circuits. A small number of such kits were designed and offered.
- The Kenbak-1 (1971) used discrete transistor-transistor logic ICs and had 256 bytes of memory. It was priced at USD 750 and sold only 40 units.
- The Educ-8 (1975) was an Electronics Australia magazine project describing a computer built from TTL ICs.

Famous quotes containing the word discrete:
“We have good reason to believe that memories of early childhood do not persist in consciousness because of the absence or fragmentary character of language covering this period. Words serve as fixatives for mental images. . . . Even at the end of the second year of life when word tags exist for a number of objects in the child’s life, these words are discrete and do not yet bind together the parts of an experience or organize them in a way that can produce a coherent memory.”
—Selma H. Fraiberg (20th century)
