Universal Enclosure PSU
The Phasor is a 12 voice sound card for the Apple II, II plus, //e and IIGS. Originally designed by Applied Engineering (aka - AE).
The Phasor is usually seen as one Mockingboard by programs which support the Mockingboard. Some programs can even see the Phasor as two Mockingboards, which allow for all 12 voices to be used. Other programs will directly support the Phasor, however the list is much smaller than those that support the Mockingboard.
In 2016 Tom Arnold worked with ReActiveMicro to reproduce a clone of the board called "FAZOR" v1.0beta. On June 6th, 2019 ReActiveMicro released their own v1.0 Phasor project. This is what is currently offered for sale.
