I remember that sucker...saw it used on a hell of a lot of R&B mixes in the mid to late 90's. I know the guys who got the last two made a few years back. 24 TT patchpoints in the front and optional XLR's in the back, you could gang multiple joystick units together (I think) if you had more than 8 channels going at once. You could also automate with a sequencer, we always ended up using an MPC. It was real hot for a while, then it kind of vanished once protools took over.
