The Supra Modem 2400 was a popular external modem released in 1988 by Supra Corporation, offering 2400 baud speeds at an affordable price point. It helped democratize online access during the late 1980s boom in personal computing and BBS culture. In the MicroBasement, it represents the era when modems became consumer staples, enabling faster connections for emerging online services. This write-up covers Supra's history, product specs, cost, features, the growing modem market and competitors, and the increasing reasons to dial up.
Supra Corporation was founded in 1984 in Albany, Oregon, by a group of engineers led by Dennis Hayes (no relation to Hayes Microcomputer Products). Starting as a small firm, Supra focused on affordable, reliable peripherals for personal computers, including modems, hard drives, and SCSI controllers. By the late 1980s, Supra became known for value-driven modems that undercut bigger names like Hayes. The company grew rapidly in the 1990s, acquiring FaxModem technology and expanding to 56K models. Supra was acquired by Diamond Multimedia in 1995, and the brand faded after Diamond's merger with S3 Graphics in 1999. Supra's legacy is in making high-speed modems accessible to budget-conscious users.
The Supra Modem 2400 was an external, Hayes-compatible modem with these key specifications:
It was backward-compatible with slower standards (Bell 103/212A, V.22).
The Supra Modem 2400 retailed for $199–$249 in 1988–1989 (about $500–$600 in 2026 dollars). This made it significantly cheaper than competitors like the Hayes Smartmodem 2400 ($499+), appealing to budget users and hobbyists. Street prices often dropped to $149 by 1990 as 2400 baud became standard.
The Supra 2400 offered competitive features for its price:
It was praised for affordability and compatibility, though sometimes criticized for build quality compared to Hayes.
By the late 1980s, the modem market exploded as BBSs, CompuServe, and AOL gained popularity. Competitors like Hayes (Smartmodem 2400), U.S. Robotics (Courier 2400), Zoom (Zoom 2400), and Practical Peripherals (PP2400) drove innovation and price wars. Supra differentiated with low costs and features like fax support, capturing budget segments. The market grew from $100M in 1985 to $1B+ by 1990, fueled by PC proliferation.
The late 1980s saw more reasons to connect: BBSs for file sharing and forums, online services like CompuServe for email/news, early Internet access via universities/providers, online banking prototypes, multi-player games (e.g., Doom precursors), and faxing. 2400 baud sped up transfers, making online time less costly (billed per minute). This era transitioned from hobbyist BBSs to the World Wide Web's emergence.
The Supra 2400 helped make modems affordable, accelerating online adoption. As competitors grew, it contributed to the dial-up boom. In the MicroBasement, it exemplifies the era's market expansion, when dialing up became essential for computing.
