in the interest of understanding, is there any code or similar for the approach? does that OCR run anywhere today?

The technology was developed by my predecessor during late 90s when microprocessors was much less powerful, and the resolution of image sensor was low. The relatively high accuracy based on those conditions was a critical factor to use Decision Tree as OCR engine. It's used till 2007 when I left my company.
I don't think it would survive afterwards due to quick change in technology. Even the desktop OCR applications at the time didn't use Decision Tree because the CPU was much more powerful. The DT OCR engine was competitive only under special use case.
