[1] The introduction of low-cost standards-based v.32bis modems made the SpeedModem disappear with surprising speed.
Two versions of the SpeedModem were released in 1991, the Champ with an introductory price of $169, and Combo at $279 which added 9,600 bit/s Group III fax support.
These were initially much more expensive, but the SupraFAXModem 14400 was released in January 1992 at $399, offering even higher performance, complete compatibility with all other modems, and adding a fax capability as well.
CompuCom responded by introducing faster 14.4 and 19.2 kbit/s CSP modems, but they were drowned out in a market flooded with v.32bis.
[6][7] These had little or no price advantage compared to other standards-based modems, and little time in the market before CompuCom Communications went out of business.
