Sup'R'Terminal




The M&R Enterprises Sup'R'Terminal was the first Apple II peripheral card to enable the display of 80 columns of text on a connected monitor.[1][2] The Sup'R'Terminal is compatible with slot 03 in the Apple II and II+. As the first card making 80 columns of upper and lower case text displayable on these machines, it is the only card supported by the II+ version of Apple Writer and thus the only way to see on a monitor the true layout of text as it will be printed on a page with this popular early personal computer word processor.[3] The Apple II and II+ had until this time only displayed 40 columns of text per line, half the characters included per line on a printed page. This transition to 80-column display was an early step in bringing the WYSIWYG concept to the Apple ecosystem.


A variety of clone add-on cards with similar functionality were released in the wake of the Sup'R'Terminal, including the Videx Videoterm. Apple's inclusion of their own first party clone of the Sup'R'Terminal, the Apple 80-Column Text Card, with the Apple IIe nearly eliminated the third party market 80-column card market.[1] The Sup'R'Terminal was designed by John R. Wilbur and the firmware was written by Andy Hertzfeld in 1980.[4][5]

(November 2014) (Learn how and when to remove this template message) The Westermarck effect , or reverse sexual imprinting, is a hypothetical psychological effect through which people who live in close domestic proximity during the first few years of their lives become desensitized to sexual attraction. This phenomenon was first hypothesized by Finnish anthropologist Edvard Westermarck in his book The History of Human Marriage (1891) as one explanation for the incest taboo. Observations interpreted as evidence for the Westermarck effect have since been made in many places and cultures, including in the Israeli kibbutz system, and the Chinese Shim-pua marriage customs, as well as in biologically-related families. In the case of the Israeli kibbutzim (collective farms), children...
