ABSTRACT:
A computer compatible master character consisting of a common dot and eight equally spaced arms extending from it is provided. Individual characters are made up of subsets of these eight arms. This system provides a total of 255 characters. Each arm corresponds to a respective bit of a computer word. Numerals constitute a subset of the character set. The master numeral has four arms--each at 45.degree. to the horizontal. This configuration for the master numeral permits a very simple photoreader to be used. Initial use was in reading the code column of a coding sheet for an 8-bit computer.
