RAM installation
Four kinds of RAM size are possible with the PlM-TBtO-
Zmotherboard. The figure below shows the location of the
RAM banks. Remember that when inserting chips in their
sockets, you must make sure that the notched end of the
chip is lined up with the notched end of the socket.

Note that for the 576K RAM and the 640K RAM options,
two different kinds of chips are used in banks 2and 3. For
576K RAM, bank 2will be filled with two 4464 chips in
sockets U63 and U59, and one 4164 chip in socket U55.
For 640K RAM, bank 2will be filled with the same chips as
were used for 576K RAM and bank 3will be filled with two
4464 chips in sockets U72 and U67, and one 4164 chip in
U76.
ROM installation
Two chips must be installed for the ROM of this system:
a2764 in socket U38 for the ROM BIOS and a27256 chip
in socket U49 for the ROM BASIC. Refer to the illustration
below for the location of these two sockets.

(Continued) .Panel indicators and switches
How you attach the mainboard to the case of your
0” for monochrome ~system unit is fairly up to you. This is because the PIM-
II Ill HIIdisplay adapter w)TBtO-Z Turbo mainboard can be used in avariety of
1234567880286-type system unit cases.
Under typical conditions, your system unit will have all
ON the indicators and switches shown below and preferably
IIIIIIEHfor one disk drive even areset switch, aTurbo hardware switch and aTurbo
123 4 5s7a'LED. If not, you can either install anew panel display or
omit some of these items from your system. Your computer
dealer offers an accessory which allows you to add the

--two switches and the LED to your system. An example of

Functions of panel indicators and switches
The PlM-TBtO-Z motherboard provides the following
connectors for your control panel:
.Keylock connector The keylock connector is located
at JP3 on the motherboard. By using akeylock device
on your control panel to put the two pins at JP3 in a
closed circuit, the keyboard is unlocked. When the two
pins are in an open circuit, the keyboard is locked.
Jill)

Reset connector The reset connector is located at
JP4 on the motherboard. if you connect aswitch to
these two pins, your computer will operate normally
while the switch is open. Closing and again opening
the switch will cause the system to reset. This is a
useful function if you are stuck in the middle of an
unfamiliar program and have no other means of
escaping from it. Using the reset function will start the
computer from the RAM test stage. Be warned,
however, that any files which have not been saved will
be lost once you press the reset button.
Power LED and Turbo LED The power LED and
Turbo LED connector is located at JP5 on the
motherboard. The pinouts for the connector are as
follows:

Hardware switch connector Turbo hardware
switch connector is located at JP6 on the motherboard.
By using aswitch connected to it, operation of the
computer can be switched between Turbo and Normal
modes. For more information on the Turbo switch, refer
to the Hardware switch section.
In addition to the connectors for the control panel
-Speaker connector Aspeaker may be connected to
JP1 on the motherboard. The pinouts for the speaker
are as follows:

Power. supply connector The power supply con-
nector IS located at P1 in the upper right corner of the
motherboard. To connect the power supply to the
motherboard, find the 12-pin connector from the power
supply (the other connectors are smaller) and plug it
into the connector on the motherboard. There is only
one way to plug in the power supply connector: aplas—
tic flange on the connector from the power supply fits
