From the project

Universal EMP-20 Family Module

The Needham Electronics EMP-20 is an older parallel-port connected device programmer that can be found fairly inexpensively and supports a wide range of older devices, so it is particularly useful for retrocomputing.

The EMP-20 requires a set of family modules to rewire the socket for particular types of target devices. Typically only power, ground, and VPP signals route through the family module.
