Shark Mx

The Shark MX is a specially designed gameboy cart that has a modem and software that lets you send and receive email, along with basic organizer functions, including semi-functional calculator and a calender which ends on dec 31st 2020.
Inside is a board with a few chips as well as some components on it along with a phone line and gameboy cart connector. :

DATEL  MBC V1  ORBIT 61763  0023  V64821.1
SST  MPF  39SF020  90-4C-NH  0010060-B
Si2400-KS  3951BCAA73
Si3C14-KS  93518CAA75

One of the chips is a custom Datel MBC which isn't compatible with any of the Nintendo MBC's. The only memory onboard is a 2mbit SST 39SF020 flash eeprom, which stores both code and data. Also onboard is a Silicon Labs 2400 baud Si2400 ISOmodem chipset.
