Everex 942 Modem

Card-ID 6612

Does anyone have the option disk for this adapter or any supporting files (beside the ADF)?
This card may also be known as the Evercom 24/2 Modem.

The official name for U1 is a "3 Wire/Microwire Serial EEPROM". An equivalent to this part is the Microchip 93AA46P. Who has the datasheet?

The short "16 bit" tab of this card is pretty bare and has only one contact finger on it. I don't know why this would be.
