I don't know why you folks are still "wondering" what this card is. Did you not visit the EBAY link I gave in my previous post, which clearly shows the cable attached and reveals it is a video card? Furthermore the test description in that auction also admits it is a video card. And as some have properly pointed out, the chips on the card itself also reveal such. No question, it is a video card. Now to do research on it, you just need to visit your local library and dig. I would be happy to do that for you but I live in Japan and cannot do such here. So take the information I provided in my previous post and go look through some old MacWorld and MacUser mags from the late 1980's to early 1990's.
I would also like to reiterate that I vividly recall seeing Ads from that company in my Mac magazines. They even had a catch phrase on their ads: "New Life for Old Macs." Interestingly, MacWorld and others in the news media latter ripped off that slogan and used it in titles of their articles in the 1990s, after Newlife Computer Corp ceased operations. You can see evidence of this when you Google "New Life for Old Macs." But from what I recall, the Newlife Computer Corp first coined that phrase, and they did so because it was part of their company name.
