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 words discrete and/or logic:
“The mastery of one’s phonemes may be compared to the violinist’s mastery of fingering. The violin string lends itself to a continuous gradation of tones, but the musician learns the discrete intervals at which to stop the string in order to play the conventional notes. We sound our phonemes like poor violinists, approximating each time to a fancied norm, and we receive our neighbor’s renderings indulgently, mentally rectifying the more glaring inaccuracies.”
—W.V. Quine (b. 1908)
“It is the logic of our times,
No subject for immortal verse—
That we who lived by honest dreams
Defend the bad against the worse.”
—Cecil Day Lewis (1904–1972)
