Reply Corp reckons there is a whole lot to be said for being first into a market even if what you offer is not the best possible option, and its answer to the demand being whipped up for low-cost Internet access terminals is to configure standard personal computers for the application. The San Jose company has therefore put together a line that at the bottom end has a $300 80286 machine, and goes up to a $1,000 586-class machine. The prices include monitor, keyboard, mouse and preloaded MS-DOS and Internet access software. The bigger models also have Windows 3.1 loaded. The machines are intended for sending electronic mail around the world, access the information on the Internet, and also to use MS-DOS and Windows applications. The company makes no secret of the fact that some parts are cannibalized from used brand name personal computers; it plans to do up to 10,000 systems a month.
