The frame looks newer than the model 15s (They also had that big puffy arm rest). Can you get a closer pic of the strips? Does it say anything on the frame? BTW, i'll be posting pics of my new toy later today. Check it out.
The modules look like a Model 10 with a custom paint job. The back plane doesn't look in anyway like a model 10 and is obviously newer than the model 10. It appears to be a 4 buss, which would eliminate the Model 15 from consideration. Yet another prototype???
Edit: It appears to be a bunch of Model 5 modules in a custom frame. I suspect that that is what it is. Possibly a Model 5 and a Model 5EX bolted together. Notice on the back panel it shows 8 inputs, then a space followed by more inputs, just as would be the case with an M5 and 5EX bolted together.
