| Atari Portfolio is a handheld IBM PC-compatible palmtop computer released in 1989 by Atari Corporation. It features an Intel 80C88 CPU running at 4.9152 MHz, 128 KB of RAM (expandable via SRAM cards), and runs MS-DOS 2.11, making it one of the first palmtop PCs compatible with standard IBM PC software. The Portfolio includes a built-in LCD screen with 240 × 64 pixels, a QWERTY keyboard, and connects via serial and parallel ports for peripheral support. It uses solid-state storage (ROM and RAM cards) rather than a hard disk or floppy drives, emphasizing portability. Intended for mobile professionals, the Atari Portfolio offered word processing, spreadsheet, calendar, and database applications out of the box. Despite limited processing power by modern standards, it was revolutionary for its time, bridging the gap between desktop PCs and portable computing. |
