This is a video from years ago showing a concept for a two line character display and AVR micro to replace the missing PB112 board. This code will likely be adapted into a library that is also compatible with the HR2510 PB112 interface. With a means to capture the display data we can make this happen easily. In fact, it would already be done if I wasn't having an issue with the display. The HR2510 has a very small space to fit the full LCD and it took a long time to locate a LCD that would fit. However, this display has stopped working after some manhandling over the years and they are, predictably, obsolete.
