We purchased Soyo motherboards directly from Soyo for our own PC production during this period.
This board was removed during a routine upgrade decades ago and has remained unused, packed in protected storage ever since.
This was one of the most popular and most reliable motherboards we ever sold.
Fully tested using Ultra-X professional diagnostics (see test results attached).
Sold without CPU and RAM so you can configure as you wish.
Supports Pentium processors 75-200MHz, AMD-K4 PR75-PR200 and Cyrix 6x86 PR90-PR166.
- FSB - 50, 55, 60 and 66MHz
- Multipliers - 1.5, 2.0, 2.5 and 3.0x
- Core - 3.3v and 3.52v (this version supports single voltage processors only).
Supports up to 256MB of 72-pin SIMMs, EDO or FPM, parity or non-parity.
256K write-back SDRAM cache with 64MB cacheable range.
In case you're wondering, the long brown slot is for optional cache expansion to 512K using a 256K Pipelined Burst SRAM COASt module.
Perpetual Dallas RTC — uses the highly reliable Dallas RTC with embedded lithium battery.
- This Dallas RTC chip has been modified to accept the easily replaceable modern CR2032 cell.

(Note: this modified Dallas RTC chip by itself is worth $30)
Option: A freshly manufactured Dallas RTC chip can be installed if you prefer. It has a guaranteed life of 10 years but the embedded battery is non-replaceable. Chip itself is socketed and easily replaceable. Request this on your order.

NO CORROSION (Dallas RTC/batteries did not leak so there was no risk of corrosion).
4-layer PCB 220mm x 280mm.
Four 32-bit bus-master PCI slots, plus four 16-bit ISA slots give you the best of both worlds.
Headers: FDD, 2xIDE, Parallel, 2xSerial, and PS/2 mouse (cables not included).
Printed copy of original manual included.
Additional manuals, jumper settings, info available here:
not included
30 day warranty.

NOTES ON TESTING :
• All low-level core functions tested with Ultra-X professional diagnostic software specifically designed to test these early motherboards.
• Tests included a burn-in loop of more than 10 minutes (see attached report for list of tests performed).
• Memory slots fully populated to test all memory slots.
• Serial and parallel ports tested using internal loop-back function.
• For practical reasons I cannot test every slot, every memory combination, every processor, every header, every port, every configuration, etc.
• Sold with 30 Day Warranty — If the board fails or a defect is found within 30 days of purchase, I will stand behind the product. Please contact me with details and we will resolve the problem or work out an appropriate solution.
