Frankenbike?

I picked up a Nishiki Regal last week and I can't find any info on these things.
serial # CD10480
Suntour shifters and f.d.
Shimano Exage r.d.
Shimano biopace chainrings
full Dia-Compe side pull brakes
Araya rims

Has Norco scribbled on the chainstay.

Is it weird to see Suntour and Shimano on the same bike??
