Mostly functioning 16 channel mic or line, 6 aux pre or post sends, 4 bus, direct outs for all 16 channels on DSUB, plus the Firewire option card. It does power up and pass signal through every mic & line input (minus channel 5) thru to main 2-mix output/headphone out. That’s as far as I’ve tested it since deciding not to repair. Channel 5 fader needs to be replaced. Channel 6 fader post is a little bent, but still works. Main 2-mix fader is a bit chonky, but works. Missing bottom panel, as it would be if you rotated the “back” input jacks to the bottom position. AS-IS condition, can be repaired or would be a great parts board.
