Hello. I have come across awhat appears to be an apple ][ clone. The Case is marked "SPIRAL ][" and the OS boots up with the message "Golden ][" It appears to be consistent with every thing I remember or have read about the ][. I am asking for information about this computer. Who made it? When did it come out. What is it's compatiblity with the apple ][? What is it's worth in the collectors market.
