Amstrad PPC640

Released in 1987, the Amstrad PPC640 was the higher-specification version of Amstrad’s portable IBM PC compatible. It paired an 8 MHz NEC V30 processor with 640KB of RAM, a 640 × 200 LCD, a full-size folding keyboard and one or two 720KB 3.5-inch floppy drives.

The PPC640 added a built-in Hayes-compatible 2400-baud modem and Mirror II communications software. Although large and heavy, it gave travelling professionals a complete DOS computer that could operate from mains power, a vehicle adapter or batteries.
