The Phasor is a 12 voice sound card for the Apple II/II+/IIe/IIgs designed by Applied Engineering. In 2016 Tom Arnold worked with ReActiveMicro to reproduce a clone of the board called "FAZOR" v1.0beta.

The Phasor is usually seen as one Mockinboard 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.

Project Status: Complete. In production. Actively sold by ReActiveMicro.


The Phasor was the second project collaboration between Tom Arnold of and Henry from ReActiveMicro. After a bit of market research there seemed be enough demand to warrant this project. Previously Tom had worked on and released a clone of the Mockingboard. This project however would be more difficult since the Phasor uses to PAL devices.

About mid February 2013 Henry sent Tom a Phasor to depopulate and start the cloning process. Tom produced a schematic and then relaid out a new PCB for alpha testing. There was no major rush in the project since Ultimate-Micro still had stock of the Mockingboard v1a they were selling. Not much was done with the project till about mid 2015.

During the whole process Tom had been trying to copy the protected PAL devices. After several weeks Tom managed to produce a good copy of "PH1". "PH2" however seemed to be a lot harder to copy. Henry sent the PH2 device to who specializes in duplicating older PAL devices. After several weeks they managed to produce a working copy about the very end of 2015.

At the very end of June 2016 Tom sent ReActiveMicro a working Phasor clone for testing and to raffle off at KFEST 2016.

Different Versions of the Cloned Phasor

Mockingboard v1 from GSE-Reactive

In late 2005 ReActiveMicro (then called GSE-Reactive) produced a clone of the board called "Mockingboard v1". ReActiveMicro sold the Mockingboard v1 in fully assembled, or in user-assessable "kit" form. There were about 50 units produced and sold. The silkscreen shows "" on the lower front.

This was the first project released by ReActiveMicro since their full-time return to the Apple II Community in 2014.
