Atari 800, with a tape recorder.. (Later upgraded to an external 5.25" disc drive.) Later moved up to an 800XL, 130XE, and then finally into the PC world with a portable 8086 with a 10MB drive, and a 2-color LCD screen. Countless PCs since then, though I dealt with a 286 long enough to bypass the 386 phase altogether and jump into a 486DX2/66.
