I bought one, but not on eBay, is's on TAOBAO (like aliexpress).
The seller claims to have more than 200 newly units in stock. In China, the seller's stock has sold out rapidly.
This TTX + is some used.
I guess it should work for a while, then be disassembled and boxed into inventory.
Its hardware configuration is completely consistent with the public TTX+ datasheet, and it has a copy of the original half life2 arcade version.
I tried to install a multigames frontend, but it cant run because I can't install the drivers for 9800PRO graphics card. Even through device manager(devmgmt.msc), or ATI's driver utility.
==================
edit: I didn't find any USB licenses in the package box. this box accessory only has power cord, DVI to VGA, and an IO board.
