The Hayes Smartmodem took the market by storm in 1981, connecting thousands of computer enthusiasts through online bulletin boards systems (BBSs) and online multi-user networks such as CompuServe. Back in the late 1970s, modems were expensive and communicated over phone lines at 300 bps - well below reading speed. They also used bulky acoustic couplers which required users to dial a number and place the handset into a pair of cushioned ports on top of the modem. Dennis Hayes and Dale Heatherington set out to change all that. Their Smartmodem was a clever little box containing a Z8 microprocessor that communicated with a home computer using the industry standard RS-232 serial port. It could be programmed to answer calls and dial numbers without manual intervention using a simple string of control characters passed from the computer. Introduced at a price of $299, the Smartmodem quickly became the industry standard. This modem is in great cosmetic condition and powers up with no problem.  Includes the original Hayes 13.5VAC power brick.  Serial number 1322094103.  30+ year old piece of computing history!   Free shipping in the Continental US, Buy It Now for just $299.99!
