Supported Device/Footprints
Using this adapter, several 68 pin microcontrollers in either PLCC
or CLCC package can be programmed 40 pin DIP programmers
Adapter Construction
The adapter is made up of 2 sub-assemblies. They assemble via
connectors making the adapter modular. This way the sub-
assemblies can be replaced when they wear out.
