Applications
The AST Research PowerExec series was a line of portable DOS-compatible laptops produced in the early 1990s, aimed at business users who needed full PC compatibility in a portable form. Running an AMD 386SX processor, this machine was capable of running MS-DOS, Windows 3.x, and the full range of 386-era DOS software. The 80387 math coprocessor made it more capable than many contemporaries for spreadsheet-heavy or engineering work. The PowerExec line competed directly with laptops from Compaq, Toshiba, and NEC in the early-1990s business laptop market. Today, units like this are sought by vintage computing collectors, DOS enthusiasts, and those doing period-correct setups for late-1980s to early-1990s software. The confirmed POST and VGA output make this unit potentially useful for parts harvesting, display replacement projects, or repair by someone with the correct 24V AC adapter.
This AST PowerExec 3/25SL AMD 386SX laptop is being sold as-is for parts or repair. The LCD screen is severely cracked — as shown clearly in the photos — and is not usable. The battery is present in the unit but will not charge, and no AC adapter is included. Notably, the system does POST and outputs video through the VGA port to an external monitor, which has been confirmed. The laptop comes with its 200 MB hard drive installed. Cosmetically the chassis shows typical wear for its age; the keyboard and external housing appear intact. Please view our photo set and contact us if you have any questions.
