The Alles Machine, also knows as the Bell Labs Digital Synthesizer, was built in the 1970’s. This video recording features Laurie Spiegel in 1977. 

In 1981, the instrument was donated to the TIMARA Department, although it was barely functioning and lay dormant till recently. TIMARA engineer, John Talbert, has repurposed the machine for future generations of TIMARA composers – thanks, John!
