In 1985, AT&T Information Systems introduced a product destined to set a new standard for business computers - the AT&T UNIX PC Model 7300, designed and built by Convergent Technologies.
What placed this PC so far out in front? Extraordinary power, exceptional ease of use, unsurpassed communications capabilities, and maximum flexibility.
No other PC offered so much at once. No other PC offered this kind of performance combination.
UNIX System V is the key to the power of the AT&T UNIX PC. It allows you to process more data faster.
Its super power lets you take advantage of the multi-tasking talents of UNIX System V. You can perform a number of tasks simultaneously on as many as 12 active windows.
And even a novice can learn to use the AT&T UNIX PC in a matter of hours, thanks to features such as a simplified keyboard, a three button mouse, and help functions.
Like the Zenith Eazy PC, the built-in monitor rotates and swivels, but cannot be removed.
The built-in 1200-baud telephone modem and software, allows the UNIX PC to initiate voice and data connections, and keep records of the numbers and connect-time.
Built into the UNIX PC is StarLAN, a '"1-base-5" 1Mbps (megabits/sec) network over twisted-pair wire.
The optional windowing manager operating system with 3-button mouse interface, while not shown here, was very advanced for its day.
The UNIX PC could support 5 additional users on their own terminals. One as-is, four more with add-on serial cards.
The later enhanced model was renamed 3B1, as pictured above. The upper case was redesigned to accommodate a larger, full-height 40MB or 67MB hard drive, expanded onboard memory to 1 or 2 MB, as well as added a stronger power supply.
