The Tektronix M187 (P/N 155-0185-00) is a 4-digit digital voltmeter monolithic integrated circuit in a 20 pin DIP, designed by Don Larson.
The M187 contains a 4-decade BCD counter, latches, a multiplexer and a D/A converter that outputs a 10-level current interfacing directly with the 7000 series readout system.
Used in
- 7B15
- 7B85 (U686) S/N B088750+ (earlier S/N use 155-0171-00 or 155-0090-00)
- 7B87
