April 2: Today in Apple history: Microsoft Z80 SoftCard, the company's first hardware, debuts on Apple II April 2, 1980: Microsoft releases its first hardware product, the Z-80 SoftCard. A microprocessor card that plugs into the Apple II, it allows the computer to run programs designed for the CP/M operating system, a popular OS for business software.

Arriving several years before the first version of Windows, the Z-80 SoftCard quickly becomes a big hit for Microsoft.

Microsoft’s Z-80 SoftCard makes Apple II a business computer

A straightforward plug-and-play peripheral for the Apple II, the Z-80 SoftCard contained a Zilog Z80 CPU and the necessary “decoding circuitry” to read the signals on the Apple computer’s bus.

It allowed the Apple II, which Apple released in 1977, to run much more business software, most notably the popular word processor WordStar, which required a Z80 CPU.

At the time of its introduction, InfoWorld magazine referred to the Z-80 SoftCard as a “fascinating piece of hardware.”

“If you need a lightweight, portable Z-80 computer, the Apple/SoftCard combination is a perfect pair,” the publication concluded.

Apple II accessory becomes a hit

The $349 card (the equivalent of more than $1,400 today) was, in some ways, a surprise hit for Microsoft. Coming packaged with Microsoft BASIC, it debuted at the West Coast Computer Faire in March 1980 and went on sale the following month. In its first three months, Microsoft sold 5,000 units — considered a big success at the time.

In fact, the Z-80 SoftCard quickly became Microsoft’s No. 1 revenue source. And it remained the company’s most successful hardware product until it introduced a mouse in 1983.

Microsoft continued its involvement with Apple for the next few years — albeit increasingly in software. By the mid-1980s, Microsoft became one of Apple’s most valuable developers. So much so that Apple CEO John Sculley signed a damaging contract to keep Bill Gates and Co. hanging around.

First came the Z-80 SoftCard, then Windows …

By the end of the 1980s, Microsoft had achieved great success with Windows. The PC operating system proved so popular that Microsoft challenged Apple in the marketplace.

Over the next 20 years, Microsoft’s software-based business model dominated the tech industry, eclipsing Apple’s own-everything-we-make approach.

In recent years, Microsoft accelerated its hardware push with its Surface lineup, producing tabletop computers, laptops, hybrid tablets, dual-screen Android devices and even touchscreen whiteboards. The company’s recent focus on artificial intelligence once again vaulted it toward the top of the market capitalization heap.
