i have a modem to match with my computer! it's a french "olitec speedcom 56000" but with a blue shell and a Wanadoo branding! Wanadoo was the internet service of France Télécom before it became Orange.
It's a "no screw" design, the back panel slides out and reveal the speaker and 2 pcbs connected to each others by a connector and rivets (??)
i managed to identify these chips inside:
- RCVDL56ACFW/SP modem
- LBA120 dual relay
- CY7C1009 1 MB SRAM
- AM29F002BT-90JC 2 MB flash memory
- MC74HCT08A quad AND gate
- MC74HCT157AD quad 2 input multiplexer
