Roland BA662 data

[Quint]

Funny I had noticed the same thing.  I'll bet they were allowed to refab them after x number of years.  They are exactly the same it would appear with the differences of the 1st 4 pins being varied.  ALL the same i/o is there.  I am definetely planning to experiment!  I'm also researching a component LMC662 which I cant really find anything on.
