Hayes Modem (Apr, 1978)
My first modem was an external 300 baud Hayes connected to an Apple IIc (there was no place inside to stick one). Man, even in 1987 300 buad was slow. It was easy to out type the display. Later, in high school I ran my own BBS, on a Supra 14.4, one of the fancy ones with the vacuum fluorescent display. I still cringe when I think about all of the hours I spent tweaking the Hayes initialization string to get everything working right.

Those of us who live on the North American continent are blessed with an incredible non-natural resource consisting of a gigantic web of tiny copper wires linking virtually all of our homes and businesses together into the greatest telecommunications network in history. The Bell System and over 1600 independent telephone companies have been stringing wires and microwaves nearly everywhere for up to 100 years. Now, the 80-103A Data Communications Adapter brings this amazing network to S-100 Micro Computers.
The 80-103A Data Communications Adapter is more than just a modem. It is a complete data communications sub-system combining on a single S-100 board functions which formerly required a modem, an automatic calling unit, and serial and parallel interfaces. This fully programmable unit gives you flexibility never before available at such a low cost. Fully assembled, tested, and burned in with full documentation and our standard 90 day warranty, the 80-103A is available at retail computer stores across the country for only 279.95.
