Reading data from X24C44 NOVRAM
The Xicor X24C44 is a proprietary combination of RAM and serial EEPROM with SPI-look serial interface, with 32 bytes capacity. To read the internal data, you need a special or universal programmer. For a list of supporting programmers, Google for "programmer for X24C44", there are plenty.

After you get the binary data from EEPROM, interpretation of binary bytes into ASCII using any decent text editor will likely help, unless the original manufacturer resorted to some encryption for some silly reason.

To read the data from X24C44, you might need to de-solder (or pull it out if socketed), although you might be lucky, and be able to read it on UNPOWERED board if the board wiring does not interfere with programmer.
