tandy 2000 cost less and performed better than IBM AT and early 286

186 and 188 have the same instruction set as the 286, except the protected mode instructions. I have read from many places that it is faster than 286 at the same clock thanks to the integrated peripherals.

The 186 architecture was better, the idea of IBM and Intel was that software houses had to use BIOS to access the hardware, in this way the differences between 8086 and 186 disappeared, but many software houses made programs that directly access the hardware to get a little more performance, so 186 was not 100% compatible with 8086 and some programs didn't work well.

So it was bound to industrial controllers (produced until 2007) and a few commercial PCs in the 1980s.
