Vtg 90s Rolodex Digital Electronic Card File 150 Address Book Brass UNTESTED

Vtg 90s Rolodex Digital Electronic Card File 150 Address Book UNTESTED. Item is being sold as a collectible conversation piece as this will only hold 4044 digits (about 150 names/addresses). This is a great example of very rudimentary digital devices--the instruction booklet is especially a reminder of how the first digital gadgets were perceived to be amazing advanced technology. Brass pocket case holds the "3K Memory Card" model of Rolodex in one compartment and bilingual French/English instruction booklets in the other compartment. The plastic protective layer on the case remains, so this likely was not ever used. Battery compartment has not been opened, no signs of corrosion, but does not turn on, may need a new battery if it is to be used. Approx 3.75" x 2.5" x .5".
