I purchased this 486 motherboard off Ebay. It was listed as a "TMC ALi M1489 A1 Vintage 486 Motherboard" I can't find any identifying information on it, and would like to download a manual for it. Any help would be appreciated. Thanks

the closest i found, based on the text on the mb, was

similar to
https://stason.org/TULARC/pc/motherboards/C/C … PCI486-AL2.html

although the layout wasn't quite the same, maybe its another version of the board

If you can get it to POST, please share a photo of the POST screen.
A bios dump would be even better (we can help you with that)

GMB-486APS motherboard is very similar:
