Cluster Eeprom orientation

Sensible_ Levanime or anyone else that may know. So I was successful in removing the chip with a hot air station, reading with the R270, editing the bin, and writing back. Now for a rookie error, how is the chip oriented on the board? I didn't note the orientation and I don't want to solder it on upside down. So if the bottom of the PCB (LCD side) is on the left, top of the PCB is on the right, left end is top and right end is bottom, would the chip numbers be readable left to right as normal or upside down? I know which is pin 1 on the chip but not the board.

With the PCB oriented as I described the eeprom would be upside down in this case. I can't say that's the case across the board though. I'll be taking a pic from now on to document it.
