I bought an Atari (8-bit) 1200XL in 1985. Returned it the next day for an Atari (8-bit) 130XE because it didn't have built-in BASIC.
I learned to program in this computer. My best work was the porting of Norton Utilities for the MS-DOS version of the Atari 8-bit -- SpartaDOS 3.2d.
Threw it away last summer because I finally moved back to Puerto Rico and the move was expensive enough.
I still have my Atari 8-bit site; obviously dead for more than 2 years:
