As hand held programmers for older Gemstart units are becoming very difficult to obtain, we thought that we should make our own.

After a lot of investigation we have designed an interface unit that allows all the functionality of the original Gemstart 2 hand held programmer to be duplicated.
Following the successful development of the Gemstart 2 HHP we recreated a version for the Gemstart 3.
Both HHP units connect to the Gemstart in the same way as the original HHP did. It allows the user to do all the things that could be done with the original, and more. With this you can:

The interface is designed to be user friendly, providing simple navigation.

The configuration data from a Gemstart can be stored using on-board EEPROM.
There is capacity for 99 Gemstarts configuration data, referenced by the address 0-99.
This stored configuration data can be uploaded to a PC based application and can be transferred to Excel for printing either as a single Gemstart.
