The Tektronix M092 is a legend generator monolithic integrated circuit (aka M92, M92A) designed by Roger McCoy and Mike Metcalf.
It consists of a a 12×10×4 ROM coupled to a 4-bit DAC with internal precision current sources requiring a single precision external reference.
The ten "memory positions" are scanned by a 4-bit BCD input which may be 0 to -15 V timeslot data or T levels or any combination thereof.
Intended applications are for encoding of CRT readout directly with electrically alterable information.
The base chip is customized for instrument-specific ROM content by metallization layer mask changes.
See the individual "programmed" chips for instrument usage: 155-0086-00, 155-0087-00, 155-0088-00, 155-0104-00, 155-0105-00, 155-0110-00, and 155-0135-00.
