Bedstead Typeface


Bedstead is a monospaced font based on the characters produced by the Mullard SAA5050 series of Teletext Character Generators. The SAA5050 is familiar to those of a certain age as the chip that produced the MODE 7 display on the BBC Microcomputer. It generates characters from a 5 × 9 pixel matrix, smoothing diagonal lines to produce an interlaced 10 × 18 matrix for each character. Bedstead extends that algorithm to continuity, converting a 5 × 9 pixel grid into an outline with smooth diagonals.
