Installing a DRAM SIMM
Before you perform the installation, be sure to read the fore-
going section “Safety precautions” and “Please note when
installing an option board/memory.”
A maximum of three memory SIMMs can be installed.
A DRAM SIMM will function correctly when installed
in any slot.
For ease of installation, we recommend that you first
use the slot that is furthest from yourself.
If you wish to use three 32 Mbytes DRAM SIMMs, you
will need to remove the factory-installed 16 Mbytes
DRAM SIMM as explained in “Removing an DRAM
SIMM.”
You must leave the AC power cable disconnected until
you finish the entire process of removing the lid, install-
ing the option board or memory, and reattaching the
lid.
1 Remove the EXB-PCM/sample memory (RAM) slot
cover as described in “Installing an EXB-PCM board”
steps
1 and 2.
2 Have the DRAM SIMM at hand.
3 Verify the location of the slot into which you will install
the DRAM SIMM module.
The three slots furthest away from yourself are for
DRAM SIMM modules. (The seven slots closest to your-
self are for EXB-PCM modules.) When the TRITON STU-
DIO is shipped from the factory, a 16 Mbytes DRAM
SIMM is installed in the furthest slot. If you want to add
one or two additional memory modules, install them in
the vacant slots. If you want to install three memory
modules, remove the factory-installed DRAM SIMM as
described in “Removing a DRAM SIMM,” and use all
three of the slots.
The end with the notch is 1 PIN. Align the 1 PIN mark
( ) of the slot with the 1 PIN marking on the EXB-PCM.
The DRAM SIMM slots and the EXB-PCM slots are
shaped identically. Be careful not to install a board in
the wrong slot.
4 At a slant, press the DRAM SIMM firmly all the way into
the slot, and raise it to the vertical position until the
catches of the slot click into the locking holes of the
DRAM SIMM. When doing so, pressing the catches of the
slot apart to the left and right will help the board go in
smoothly.
5 Reversing the procedure by which you opened the EXB-
PCM/sample memory (RAM) slot cover, reattach the
cover and fasten it with the screw.
6 When all steps have been completed, turn on the power
and make sure that the DRAM SIMM has been installed
correctly. (“Checking after installation” ☞p.287)
Removing an DRAM SIMM
• Spread the catches of the slot apart to the left and right,
and (after removing the stoppers from the catches) tilt
the DRAM SIMM and pull it out.
If you wish to remove the rear DRAM SIMM board, you
must first remove the forward DRAM SIMM.
When you spread the catches of the slot apart, the
DRAM SIMM may pop out vigorously and fall into an
opening (inside the instrument). Please be careful.
