ATI Ega Wonder !
Back in '86/'87 as a high school student, could not afford a EGA/VGA monitor.
The EGA Wonder ! let you plug into a monochrome monitor and run EGA/VGA games.
I remember purchasing a $10 game from Waldenbooks, some horrible baseball game. It wouldn't boot on the card.
Contacted ATI in Canada, and they sent me a new EEPROM to install in the card with a return carrier for the old one.
That customer service, as a youth, is likely why I went on to buy the VGA Wonder !, Rage, 9700, 6850, 7850, 3900, 480 and 580 graphics cards.
