Sequential circuits samplers

the plot thickens .

just opened a keyboard version prophet 2000 (sampling keyboard;)

and to my surpise there was a mix of cem 3379 /8540     and 3379 /8542 installed.

I don't see any info on the net about the added nrs. on the cem 3379 chips.

I swapped the chips from the 2002 boards today and both units worked fine  .

cheers,
David
