This is the first computer I bought with my own money, as a college student. At the time this was the perfect system for a school work...no more waiting in line in the computer lab for an IBM XT or MAC SE with the other students. The Model 8525 first appeared in the Spring 1987, just after the initial PS/2 launch.
Model 1391472 model M "space saver keyboard" had no number pad.
This system shipped with DOS 3.3. I purchased the optional Windows 1.04 "Collegiate Kit" that had early versions of Winwrite and winpaint programs. To print I used an IBM ProPrinter II. More photos... [ read more ]

The Atari 130XE Computer.
Here is a view of the rear ports. Note that a person could still use Atari 400/800 carts on the 130XE model. In many ways the 130XE was the Atari equivalent of the Commodore 128 in that both were backwards compatible and both were primarily used by their owners to run older software originally purchased for an older model system. As with the C-128, there were not as many 130XE-specific software packages was produced.
