The Intel D845GECL motherboard is ideal for building an older retro computer where you want the extra processing power of a Pentium 4 but still have the use of your favorite ISA sound card.
This is an OEM industrial motherboard built by Intel for use by Siemens and is comprised of high quality parts. These particular boards were used in France's "La Poste" postal service kiosks which eventually made their way to Hong Kong to be recycled.
I bought two of these units for hobbyist tinkering and they've been quite fun to work with. I've done extensive testing with these and they're absolutely flawless as a retro board and is very compatible with QEMM for allocating lots of UMBs for TSR loading. There will be plenty of memory available for your favorite games.
This motherboard supports ISA Bus Mastering for DMA (Direct Memory Access); this means it is compatible with old DOS-era sound cards. I've tested it personally with a Gravis Ultrasound, SB16, AWE32, and AWE64.
This item is guaranteed to not be DOA but its condition otherwise is as-is. I have two of these boards for sale (each auction is for just one) and both are identical aside from a few pieces of circuitry on the board being different colors. So don't be alarmed if you get the board that isn't pictured; they're exactly the same!
Tested with Pentium 4 2.66Ghz and 3.06Ghz processors-- they work great!
