The Tandy 1000 SX was similar to the Tandy 1000 (see this entry for more info about the Tandy 1000 series).
The difference with the original model 1000, is that the CPU (Intel 8088) can be set to two different speeds: 4.77 MHz and 7.16 MHz thus offering more speed than the original IBM PC on the same software. The SX also comes with more memory (384 KB) than the Tandy 1000 (128 KB).

Why do you guys talk in past tense? Mine is still played by my kids. Mine is seriously upgraded and maxed out. I debate all the time on restoring the yellow case, but I''m afraid if I completely tear it down, it won''t turn back on when I put it back together. There are some awesome mods available to use SD cards out there so you don''t need the floppies anymore. I learned to program on this computer in 1990.

I stand corrected, the 8088 was the correct model of cpu, a variant of 8086 with "turbo" mode... (I got it in my head the other way around, but a few searches made me remember 8086,286,386...), I loved that computer btw, King''s Quest II was a delight for that time and my age...(never played the I :( )
