Atari Portfolio
The Atari Portfolio, introduced in 1989, was the first MS-DOS-compatible handheld computer. Developed by DIP (Distributed Information Processing Limited) and later licensed by Atari, it was the size of a VHS cassette and weighed 505 grams, making it a precursor to later PDAs. Powered by an Intel 8088 processor, the small computer featured built-in ROM-based applications for spreadsheets, word processing, scheduling, address management, and a calculator. I bought my Portfolio from Quelle and exchanged data with my PC using a suitable cable and a serial interface. My collection now includes various models, including a variant with a faster processor and a CF card slot.
