[Vincenzo] wanted to read some 82S129 bipolar proms, and why not, they were very common in the 1980’s arcade scene. The problem is that its kind of an odd ball part now, and typically only (e… ...

That’s all you need to know in order to use and external serial EEPROM chip with your Arduino. As mentioned before, this is basically a dirty experiment with the 24C256 module. So, if you plan to use ...

Yes, you are absolutely right, using a board with several real hardware serial ports is the obvious solution. That obvious solution is named “Arduino Mega” and generally is priced at $60.
