Oddball Alesis Display Module 6 Ch Audio Switcher?

via this auction
Anyone familiar with this one?
"This auction is for an oddball Alesis project that was probably for a NAMM show or maybe some other demo environment. It would be great for a store or other place where you need to switch between up to 6 audio inputs for comparison.

It appears to be a 6 input stereo audio switcher. Please note that the description comes from my inspection of the board and does not imply that I really know what this is or where it came from! ;-)

The unit has what appears to be 6 stereo inputs on 1/4" TRS jacks and 1 stereo output on a L/R pair of 1/4" jacks. There are actually places on the board for two more stereo audio inputs, but I imagine you'd have to hack the firmware to make it work. There are also two headphone outputs with volume control. Most of the audio path is TL084 with a couple of NE5532's thrown in for good measure. The switching is done with relays. I can hear them switching, but have not actually hooked up any audio level signals to the unit. The unit has a 2 line by 16 character back-lit LCD display (with contrast pot) that shows the current selection. Selection is made via a pair of up/down switches.
Finally, the auction includes a 9v AC adapter typical of Alesis products (of that time). The display cycles the following 6 items:

- Alesis QS7
- Alesis QSR
- Alesis DM5
- Alesis NanoSynth
- Alesis NanoPiano
- Alesis NanoBass

But of course you can plug anything in you want.

The unit does not have a case, but I will pack it well so that it survives shipping. The board uses an 8031 CPU like in the HR-16 and MMT8 families and it has an external EPROM. This would allow you to hack the unit quite easily if you are experienced in writing code or reverse engineering. The unit would be great fun for a hacker or ex-Alesis employee."
