Atari Portfolio (1989-1993)

✅ Atari Portfolio

🥇First Commercially-Released PalmTop PC 

The Atari Portfolio, released in June 1989 for $399 (roughly $1,040 in 2026 dollars), was the world's first palmtop PC, squeezing a nearly IBM-compatible MS-DOS environment into a chassis the size of a VHS tape. Originally developed by DIP Research in the UK as the "Pocket PC," it featured an 80C88 CPU and ran for weeks on just three AA batteries, making it a favorite for 1980s power users who needed a "Lotus 1-2-3" compatible spreadsheet on the go. Its pop-culture immortality was sealed in 1991 when a young John Connor used one to hack an ATM and a security door in Terminator 2: Judgment Day, a feat that real-life enthusiasts still recreate today using "T2-PIN" software and custom parallel-port cables. In 2026, the Portfolio remains a highly prized piece of "Cyberpunk" tech; while original memory cards are rare and expensive, the modern community has developed SD-card adapters and internal 512KB RAM upgrades to keep these 4.9MHz workhorses functional. A clean unit typically sells for between $200 and $400, though the "John Connor effect" means prices often spike whenever a new Terminator project enters the cultural zeitgeist.
