Motorola MODCOMs were very popular in my county. One police department received their MODCOM late in 1970, while the county sheriff purchased a newer edition in 1977 for their teletype operator position. The big difference between the two, was the older one had flashing lights, while the newer edition used LEDs like their Centralcom consoles did. Also, one of the fire departments had one they purchased in 1973.
Here is the 1970 edition.
