PAK-GAL V4-50ac (at the time of printing of the manual) 1.3 Requirements The PuPla/2 is suitable for all Atari ST models that work over a 68000 bus (ST, MegaST, STE and MegaSTE). The E-models might still require a PLCC-to-DIP adapter. When in doubt, please contact us. -
Page 5: Features Of The Pupla/2
The PuPla/2 is always installed "under" the CPU - regardless of whether you use the PAK or 68000 since some lines have to be interrupted. This means that to use the PuPla/2 in any way the CPU must be socketed. -
Page 6: The Construction
3. Installing the PuPIa/2 3.1 Preparation The CPU must be socketed in order to install PuPla/2 since it must operate on or above the PuPla/2 board itself. If your CPU is not socketed, then the best way to do this is to use a fine side- cutter and snip the CPU pins close to the mainboard. -

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. -

3. Installing the PuPla/2 Also, you must replace GAL U4 on the PAK in order for the address latch feature of the PuPla/2 to work. If the GAL V4-50ac was included in your order, you can now use it to replace the PAK GAL U4. -

4. Configuring the PuPla/2 As you can see, the installation of the PuPla/2 in systems with PLCC CPUs is not very easy. Please contact us if necessary. If you are able to successfully "implant" the PLCC-to-DIP adapter then the installation is the same as described in Chapter 3.2 since basically the system now has a DIP design. -

Connected to pin C3 of Panther/2 bus adapter Not connected when there is no Panther/2 adapter 4.2 The GALs The PuPla/2 has two 20v8 GALs for flow control. GAL1, labeled "PUFCTRL" on the silkscreen. This GAL is responsible for controlling the buffering capabilities. The current equation for this GAL is named "PUF2-004". - Page 11 5 can be triggered. This solution is not that bad since we don't know any extension that has these requirements. If you are unable to update the PuPla/2 AVICTRL GAL yourself, you can get a free GAL update from us.
