Motorola CyberSURFR Cable Modem

Specifications page

This is a non-DOCSIS cable modem.

Specifically, it uses Motorola's proprietary CDLP system.
See  • modem#CDLP Cable modem#CDLP on Wikipedia for a bit more info.

Early @Home Network installations may have been the principal

users of these modems.. though some post @Home networks
may have kept the legacy network going for a bit longer.
The front of the Motorola CyberSURFR has a curved face plate and six small lights.
The Comcast@Home logo is a stick-on label on the otherwise gray metal case.
Instead of two RJ-11 telephone jacks on the back, it has a "cable TV" connector
(female Type F connector), an RJ-45 10BASE-T Ethernet port, an odd 9-pin D-shell
(DB 9-pin male) connector for "testing," and a tiny reset button.
