Tested 1995 Diamond Stealth 64 DRAM T PCI 2MB graphics card, S3 Trio 64, 86C764
AU $33.33
It uses S3's 86C764 graphics processor, better known as the Trio64, which was one of the first 64-bit GPUs. This card has been upgraded from 1MB to 2MB of FPM RAM, and is not further upgradeable. I have tested it successfully in two systems.
