First owned: Atari 130XE, 6502 processor at 1mhz, 128k RAM (via bank switching), one floppy drive, running AtariDOS 2.0 or 2.5, and PaperClip word processing software (neat, because it had a spell-checker), and VisiCalc, (of course); hooked to an Epson LQ800 24-pin dot matrix printer. Running (or attempting to run) 6502 assembly language on the mother was fun....
