When, early in the history of personal computers, users didn't find their character encoding requirements met, private or local code pages were created using Terminate and Stay Resident utilities or by re-programming BIOS EPROMs.
This shrine differs from the one at Santiago Atitlan in that an EPROM chip, presumably from a novelty Christmas Card, has been rigged up to speakers and plays a continuous loop of a few bars from three Christmas songs at volume.
A typical model consists of a microprocessor, a modem, and software (in EPROM) that implements the AX.25 protocol and provides a command line interface to the user.

Some applications of the FGMOS are digital storage element in EPROM, EEPROM and flash memories, neuronal computational element in neural networks, analog storage element, digital potentiometers and single-transistor DACs.

Using the FGMOS as a programmable charge element, it is commonly used for non-volatile storage such as flash, EPROM and EEPROM memory.
