this auction"The unit has a mono Master Output, individual Outputs for each of the 8 parts, MIDI In/Out/Thru, and various Sync options...
A fair amount of restoration work has been recently done on this unit. Most notably, a new Noritake VFD display replaced the faded old LCD display.
The Record In and Master Out knobs were bypassed. (The idea behind this is to preserve the unique sonics of the unit as much as possible and to increase reliability over time. The unit now always inputs and outputs at maximum level.

I/O Levels can still, of course, be controlled at your mixer.)
A few of the drum pad bottoms (the spring-loaded portion of the drum pad) were very worn, and were replaced with NOS parts.
A worn slider was replaced with a NOS original part. One of the original SSM2044 analog filter chips had gone bad, so it was replaced with a NOS one as well. Finally, the worn E-Mu knob that controlled Metronome Volume was replaced with a much higher-quality UREI knob, with set screws. (The original knobs were much cheaper and did not have set screws.)...

Some extras are included: (4x) boxes of unused blank Maxell 3.5" discs, (16x) Sample Library discs, an OS Boot Disk, a paper copy of the Manual, (2x) spare NOS pots for Master Volume and Input Volume, (2x) spare drum pad bottoms (this is the spring-loaded part that sits inside the machine), a spare NOS SSM2044 analog filter chip, and a spare NOS slide fader."
