3. Installing the PuPla/2

At this point you should have the computer "opened up" in order
to install the PuPla/2.
The installation options depend on whether you have a PAK or
not and the CPU design of the mainboard.
3.2 Installation without PAK / DIP CPU
The installation of the PuPla/2 without a PAK is really only useful
if you want to use the Panther/2 ISA Adapter with a network card.
In this case the PuPla/2 jumpers should be configured as follows:
J1 closed when the Panther/2 is installed above the PuPla/2
otherwise left open
J2 open
J3 open
J4 (bottom pin) to pin C3 of the Panther/2 bus adapter
The CPU and Panther/2 bus adapter can now be placed on the
PuPla/2 (we recommend the use of the Panther/2 on top of the
PuPla/2) which can then be plugged into the mainboard. With
this the installation is complete. Thus, this is the sequence from
"bottom" to "top": Mainboard - PuPla/2 - Panther/2 - CPU.
The exact meanings of the jumpers are explained in Chapter 4.1.
3.3 Installation with PAK / DIP CPU
This is probably the most common variation, since the PuPla/2
was mainly developed as a buffer board for the PAK. Remove
the PAK and, if you have one, PuPla/1 from the mainboard. Also
remove any existing connections to the Panther/2 adapter. Then
configure the PuPla/2 jumpers as follows:
J1 closed when the Panther/2 is installed above the PuPla/2
otherwise left open
J2 depends on whether you use a 68000 in the alternate
operating mode on the PAK. See Chapter 4.1
J3 (bottom pin) to PAK U1 pin 20 via a 68 ohm resistor close
to U1
J4 (bottom pin) to Panther/2 pin C3 or open if no Panther/2
adapter is equipped.
