Hello
The FA-1 is pretty much the same as the KN portable and the digital piano that were out at the same time.
Technics would basically make one computer brain for their current models and used it in their portable, digital piano, and organ. They just charged different amounts for them.
I knew of Technics dealers that kept their portables hidden in the back room or would not even stock them, because it was kind of hard to explain why the KN would be a few thousand dollars and the same thing in the organ could retail around $50,000.
