RAM EXPANSION
User RAM in the 02000 may be expanded with the installation of
SIMMs (Single In-line Memory Modules) in pairs. SIMMs for the
K2000 must be 30 pin, 8 bit, and 120ns or faster, with maximum
dimensions not exceeding 3.5" wide x 2.2" high x .25" thick -
SIMMs
with ICs on both sides are not supported. The following
memory sizes are supported:
256KB x 8
1MB x 8
4MB x 8 16MB x 8
Installation of SIMMs:
Turn the unit off and remove the AC line cord from the AC power
connector.
Open the unit as described
in Section 3, "Disassembly".
Locate the SIMM sockets on
the Engine board (Figure
2.6). There are two banks
of SIMM sockets, the two
inner sockets are Bank A and
the two outer sockets are
Bank B. When installing one
bank (2 SIMMs), install the
SIMMs in the Bank A sockets.
When installing two banks (4
SIMMs)
of different sizes,
make certain the 2 SIMMs in
the Bank A sockets are the
same size, and the 2 in the
Bank B sockets are the same
size.
Insert a SIMM into the proper
socket at a 60 angle (Figure
2.7) •
Press the SIMM firmly into
the socket until it clicks
into place.
Pull the latches on each end
of the socket outward, rotate
the SIMM to a vertical
position, and release the
latches.

installation - make sure the top edges of all like SIMMs are at
the same height and parallel to the printed circuit board.

To verify the SIMMS are functional:
1. Plug in the power line cord, and turn the unit on.
2. After the K2000 has initialized, press the "DISK" button.
3. Confirm the "Samples:####K" figure displayed in the center of
the status bar corresponds to the total amount of user RAM just
installed.
