Diamond Supra Sonic II Shotgun PC Internal ISA Modem 112K (Dual 56K) 2 line bond

Description

This is a rare vintage Diamond Multimedia Supra Sonic II Shotgun internal modem.
This uses dual phone line bonding technology to achieve 112K speeds.
This is achieved via Multilink PPP (MPPP) technology.
This was excellent during the late 90s when broadband was not yet available and ISDN cost too much for home or office use.
I am the original owner of this piece and at that time, I used my phone line and fax line dialing up via this modem achieving double dial-up speeds.
Excellent historic value!
Come with original installation CD.
Online news information back in late 90s (Nov 5th, 1997):

Diamond this week debuted Shotgun, a technology the company said will double the connection rates of 56-Kbps modems by combining the bandwidth of two analog telephone lines. Diamond said the technology takes advantage of the two phone lines available in many households.
Shotgun-based devices will be able to achieve speeds as fast as 112 Kbps, according to Diamond. The company said Shotgun modems for Windows systems will arrive in the first quarter of 1997, and the company said it is reviewing whether to bring the architecture to the Mac.
Developed in conjunction with remote-access vendor Ascend Communications Inc. of Alameda, Calif., Shotgun taps Ascend's Multichannel Protocol Plus (MP+) technology, which combines two modem connections on the Internet service provider side, according to Diamond. MP+ is already supported in Ascend's line of MAX switches.
Shotgun will use a consumer's second phone line during peak Internet usage and drop the dual-line connection during times of lower Internet traffic, according to the company.
Diamond said Shotgun will reach ISDN speeds without requiring a special digital phone line and extra phone company fees. Many ISDN devices use a technique called MultiLink Point-to-Point Protocol, similar to MP+, to combine two B channels in order to achieve speeds of about 115 Kbps."
