This is only internal Zorro II modem card I'm aware of for the Amiga (except the modem 19). Its a 2400 baud modem and appears to have a speaker on the card. Connects via a two Western connectors mounted on a "slot blech" to the analogue line (not shown in this photo). It is possible to upgrade this card to a 9600 modem by using the Intel (Satafaction) 9600 V32 Modem chip set.
