Fully Tested with 30 day warranty against defects

Manufactured by Soyo in October 1995. We purchased directly from Soyo Nov 29, 1995 for our own PC production.
This board was removed during a routine upgrade decades ago and has remained unused, packed in protected storage ever since.
Fully tested using Ultra-X professional diagnostics (see test results attached).
Intel Pentium 75 MHz installed
16MB 60ns Toshiba EDO DRAM installed.
Perpetual Dallas RTC — modified with an easily replaceable modern CR2032 cell.
Includes — universal floppy cable, supports both 3.5" (pin connector) and 5.25" (card edge) floppy drives.
Includes — dual IDE cable, supports two drives.
Includes — IBM parallel and DB9 serial header cables.
- Note: Not widely known is there are TWO standard configurations for COM port headers: DTK and Everex (AKA staggered and sequential) which are completely incompatible with each other. Using the wrong header cable won't work at all (the signals will be on the wrong pins). Most online sellers do not identify the type they're selling, which can lead to immense frustration if it's the wrong type. The included DB9 header cable is correct for this board.
Includes PS/2 mouse header, but cable is not included (available on ).
NO CORROSION.
Includes p rinted copy of the original manual — High resolution scan of the original manual with all jumper settings.
30 day warranty.

• Tests included a burn-in loop of more than 10 minutes (see attached report for list of tests performed).
