Tseng ET4000 PCI: A VGA Card With Major Flaws!

This video is brought to you by PCBWay #sponsored The Tseng ET4000 is typically available for the ISA bus, but this particular example is for the PCI bus. I recently found this card at the scrapyard and wondered how well it would perform in DOS and Windows. I really should have left it there. You'll understand why once you watch the video. ▬▬▬▬ PCBWay ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ Sponsored by PCBWay: 🔸https://pcbway.com/g/lF253I PCBWay provides full feature custom PCB prototyping services, 3D printing, and much more.
