Upgrading Sample Memory
Choosing and Installing a SIMM for K2661 Sample Memory

Installing Sample RAM
There’s an access panel on the underside of your K2661, which you’ll need to open to install
your sample RAM. This is the same panel you would open to install a replacement battery or
ROM sound block options.
Warning : Turn off your K2661 and disconnect the power cable!
1. Carefully place your K2661 upside down on a padded level surface, with the front of the
instrument toward you. Use soft, sturdy foam under the ends of the instrument, to protect
the wheels and sliders.
2. Locate the access panel. It’s about 6 by 13 inches in size, slightly to the right of center,
toward the back of the instrument.
3. Remove the eight screws that hold the access panel in place, and swing the panel open
from the front. It hinges at the back, and rests in a position that’s convenient for referring
to the diagram that’s printed on the inside of the panel.
4. Locate the socket for sample RAM.
5. Remove the installed SIMM and store it in a static-proof bag.
6. Place the new SIMM into the sample RAM socket. There’s only one way that a SIMM will
fi t into the socket. Be sure the clips at the sides of the sockets snap into place.
7. Check the setting of the voltage jumper, and change it if it doesn’t match the voltage of
your SIMMs. The K2661 arrives from the factory with the jumper set for 3-volt SIMMs.
Since most SIMMs these days are 5-volt, you’ll probably need to change the jumper
setting.
The jumper is a small piece of molded plastic with a wire loop at the top. It has two slots
that slide over two of the three pins that stick up from the circuit board. The pins are
numbered from 1 to 3,
right-to-left . Put the jumper on pins 2 and 1 (the two right-most
pins) to con fi gure the K2661 for 5-volt SIMMs, or on pins 3 and 2 (the two left-most pins)
to con fi gure it for 3-volt SIMMS. The circuit board is labeled accordingly.
We set the con fi guration for 3 volts so that if you were to install 3-volt SIMMs while
thinking you were installing 5-volt SIMMS, you wouldn’t pose any risk to your
instrument.
8. Replace the access panel and loosely install the screws, starting with those closest to the
hinge (the back) of the access panel. When the screws are loosely in place, tighten them all.
