Plus/4 Encyclopedia First Back Next Last Tech-Tech Category Glossary/Demos Topic Also know as Tec-tec and Tic Tac, Tech-Tech is a demo effect, where a logo (or some other graphics) is "waved", but the shift along the x-axis is greater than 8 pixels. The name may come from the Amiga demo Tech-Tech (Pouet.net). Graphics can be waved easily by modifying the $FF07 TED register for each scan line, however, this allows for only 8 pixels movement - hence the difficulty in acheiving this effect. Examples: Icaos Demo/SCF has two Tech-Techs. Keywords tech-tech,tec-tec,tic tac  Copyright © Plus/4 World Team, 2001-2013
