Character Set Conversion System

The system includes facilities for converting character sets between magnetic tape media, that are otherwise incompatible with the system, and performing merging operations.

The basic system at A includes an IBM SELECTRIC Composer unit 1 interconnected with tape unit 2 having provision for reading and recording information on magnetic tapes at tape stations 3 and 4. The system also includes control panel 5 that is arranged, as at B, for establishing conversion and merging operations. Also included in the system is tape unit 6 with facilities for reading and recording on a single tape media at tape station 7. The various conversion and merging operations are controlled by circuits 8.

The two primary kinds of tapes used and converted in the system are the Magnetic Tape SELECTRIC Composer MT/SC tape that uses a single character set and the Magnetic Tape SELECTRIC Typewriter MT/ST tape that is provided in three character sets. These are the MT/ST-N Numeric, MT/ST-S Standard, and MT/ST-NF Numeric and Fractions. The character set and the Magnetic Tape SELECTRIC Typewriter MT/ST tape that is provided in three character sets. These are the MT/ST-N Numeric, MT/ST-S Standard, and MT/ST-NF Numeric and Fractions. The control panel at B has a row of keys actuated to enter information in a sequence indicated by lamps 10...14. Clear lamp 10 is on primarily for program changing. Input Tape lamp 11 indicates that the operator is to select the type of input tape among keys 4...7, as one of the types previously mentioned. Lamp 12 defines the type of output tape to be prepared, again as selected by depression of keys 4...7. If Control Codes lamp 13 is on, depressing the yes button indicates control codes in the original tape are retained. Depressing the no button indicates they are to be eliminated on the ou...
