[Skimmertalk] RU9CZD skimmer QS1R died in the recent thunderstorm. Help needed.

Here is what datasheet says: (link to datasheet - 
https://static.chipdip.ru/lib/260/DOC000260334.pdf)

Software: 8051 code runs from:
❐Internal RAM, which is downloaded through USB
❐Internal RAM, which is loaded from EEPROM
❐External memory device (128 pin package)

So you recon the internal 8051 is loaded through USB or from external 
memory when connected to  a computer?
