"This unit was used by Cornell University's Psychology department for perceptual studies. Also used by its previous owner to generate vector waveforms for laser light shows.
Inside are all Emu sub-modules. It has 3 Emu Universal Audio Filters, 4 VCAs, a VCO and a noise / random signal generator.
The unit wasn't built very well and arrived complete broken. A lot of work, but it's all happening again. Ugly, but lots of sizzling filters :)"
Update via dougt in the comments:
"Yes the UAF is an amazing unique filter - incredibe resonance without oscillation. I have one in a home-made standalone box -
