23 magg 1973 anni - The TV Typewriter plans are published

Descrizione:

Designed by Don Lancaster, the TV Typewriter is an easy-to-build kit that can display alphanumeric information on an ordinary television set. It used $120 worth of electronics components, as outlined in the September 1973 issue of hobbyist magazine Radio Electronics. The original design included two memory boards and could generate and store 512 characters as 16 lines of 32 characters. A cassette tape interface provided supplementary storage for text. The TV Typewriter was used by many small television stations well in the 1990s.
