Note: The Enhanced Resident Sound Block can only be installed
in units with Version 3.1 or better. Therefore units that
currently have Version 2 or 2.2 must be updated when ordering
the Enhanced Resident
Sound Block.
Note: When installing the Enhanced Resident Sound Block in
units with sampling, be sure to remove the 20 DRAMs from the
old
CGP and reinstall them in the Enhanced Sound Block. If the
unit has a
Sound Block A board with the 10 Sound Block A chips
socketed, the chips may be removed and installed
in the
Enhanced Resident
Sound Block (see Enhanced Resident Sound
Block Configuration list).

*Units with
Sound Block A boards may have either Sound
Block B, C or 0 added. Should a customer desire to add Sound
Block B, C or D the customer would have to have the
Enhanced Resident
Sound Block installed as there is only
room for one additional sound block to the
Sound Block A
board.
**The Ram Sequencer Expansion bringing the unit from a 4K
sequencer memory
to 8K sequencer memory is required with
the installation of
Version 3.1; because version 3.1 brings
the sequencer memory
to 12K.
***QLS may only be installed in units with sampling.
