This is essentially an ATI 600 USB clone, but using generic eMPIA bridge drivers instead of the ATI custom drivers.
But you must be careful, as Tevion had no model numbers, shared UPCs. What you normally see sold are the non-TI chipset devices, so never buy from places like
Amazon, or any eBay/Craigslist post using stock images. Not that it appears for sale much anyway. Sometimes a whole year can go buy, and I don't see one anywhere. I've written to
Amazon sellers in the past, and they never respond.
I installed this on my Win8 and Win10 tablets last year, just to see if it would work. And it did. The drivers and audio are hackish, but I wrote instructions for it. You also need a specific driver, which isn't easy to find. (I'm not on my main video computer right now, so no access to any of it at this moment.)
Aldi sold it for $55 (with tax) at first, then quickly clearanced it out at $30. I bought several at both price points. That was more than 10 years ago.
I'm also pretty certain it was made only for Aldi, and that would make sense -- Tevion is a European brand, rebadging/cloning various electronics, and Aldi is of course the German discount grocery chain. While most stuff is from Batavia IL, they'd import quite a bit of things from Europe. It also explains the scarcity.
Update: Drivers attached!
