The Tandy 1000 line was a great DOS machine of its moment for games, because the 1000 wasn't just a PC clone, it was a better version of the PCjr -- it had better sound and graphics out of the box compared to PCs, with better actual PC software compatibility and without the horrible chiclet keyboard. The 1000 was so successful for a while that games that supported the PCjr's enhancements were marketed as "Tandy-compatible".
