2. Building the PuPla/2
PuPla/2
Page 4
Although the PuPla/2 was primarily designed for the PAK68/3, it
is also possible to operate with the 68000, i.e. to use a network
card with the interrupt-enabled Panther/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.
Unfortunately, the PuPla/2 is not suitable for the TT or Falcon!
1.4 Features of the PuPla/2
Complete buffering of the address and data bus
Additional buffering for the main control signals
CPU-side damping resistors on the data lines
Address latch when used with the PAK
Convenient configuration via jumpers
Mainboard interrupt logic for the Panther/2
Small dimensions due to SMD components
2. Building the PuPIa/2
2.1 Prerequisites
This chapter isn't relevant to owners of the finished device. If this
applies please continue reading from Chapter 3 onwards.
We assume that the empty board has been purchased by
persons who know what they are doing and can get the
components themselves. Those that have purchased the parts
kit need only experience in soldering SMD components and the
necessary equipment. We would like to point once again that the
circuit and board have been developed and tested with great
care. So if your self-built PuPla/2 does not work correctly, check
for construction errors first. If, after checking the board, you still
need to take advantage of our services and it turns out that the
error was caused by improper assembly, our service is not free!
