#28 - EEPROM programmer - BB816 Computer
In this video, I program the Teensy monitor to be able to program the EEPROM in-circuit. With that, I can iterate on the computer code without constantly having to extract the EEPROM and put it into my TL866!
By making use of all the work we did previously, notably on ensuring Bus Enable works properly, I'm able to do this quickly with minimal hardware changes.
