Physical Layout
The Kingston Technology 486/Now! Processor upgrade board has 3 different board
type models. Each board type is available with either a 33Mhz DX or 33Mhz SX
version. There is also a 25Mhz SX version for the PS/2 Model 70 and 80 computers.
The first board type, model 486/33PD3, 486/33PS3 or 486/25PS3 support PS/2
Models 70 and 80. See Figure 1-1 and 1-2. The second and third board types support
the PS/2 P70 portable. The 486/33PD3-P70 and 486/33PS3-P70 support the P70
20Mhz model 8573-061. See Figure 1-3 and 1-4. The CPU socket is located to the
right of the SIMM sockets on the system board. The 486/33PD-P70LP and
486/33PS3-P70LP support the 16Mhz model 8573-031 and the 20Mhz model 8573-
121. These system boards have the CPU socket located above the SIMM memory
sockets. This board type also supports the PS/2 Model 5530. See Figure 1-5 and 1-6.

Switch Settings
The 486/Now! contains a 4-switch block (SW1) mounted to the processor upgrade
board. These four switches must be set to your specific computer motherboard's
speed. The IBM PS/2 Model 70 and 80 can have either a 16Mhz, 20Mhz, or 25Mhz
system board. There is only one setting for the P70 Models, but they are listed
separately by board type. Use the following table to determine which motherboard
you have and match the appropriate switch settings to SW1 on the 486/Now! upgrade.

* Note: SW1 Switch 4 default is set to the ON position. This allows the 486/Now processor to run
POST (Power-On-Self-Test) at a fast 486 level. In some cases, an 8603 mouse error will occur because
of the faster speed. Also if an IBM XGA adapter is installed in the system and a display problem occurs,
changing Switch 4 to OFF should correct either problem.

STEP 1
Turn off power and disconnect any cables from computer.
STEP 2
Open the chassis and remove all expansion-bus adapters. (Label each adapter so you
can return it to its original slot).

Model 70 16Mhz Installation 7
STEP 3
Remove the 386 CPU chip on the motherboard by using the IC removal tool. Carefully
insert the IC removal tool on one side between the 386 CPU chip and the socket.
Gently pry upward to lift just a little, then lift slightly from other side. Alternate
between sides until the chip is completely out of the socket. (Save the 386 CPU chip
so you can re-install it if you ever need to return temporarily to the old configuration).
See Figure 2-1.
Note: You may remove the Fixed Disk Drive, Floppy Drive, Adapter Card, and the
internal holder chassis to clear the area for easier installation.
STEP 4
Remove the 387 Math-Coprocessor on motherboard, if present, by inserting the IC
removal tool on one side between the 387 FPU chip and the socket. Gently pry upward
to lift just a little, then try other side until the chip is completely out of the socket. See
