HP Portable Plus

The HP 110 computer, also known as the HP Portable, is a portable MS-DOS computer produced by Hewlett-Packard. It has four-times the screen display as the popular but older TRS-80 model 100, and runs at over 5 MHz. The HP-110 weighs 9 pounds, with battery life of up to 16 hours. it runs MS-DOS 2.11 (in ROM); BASIC is not built-in and must be loaded from an external drive. Built-in RAM of 256K is provided, with in-ROM applications including MemoMaker, Lotus 123 and a terminal emulator. Since the applications are executed directly from ROM, more RAM is available for user data. The RAM is divided between system RAM and electronic disk emulation - a RAM-disk. Application data is stored on this virtual disk drive, which is fully MS-DOS compatible - it can even be formatted. Since the CMOS-based RAM is very power-efficient, stored data will be kept for months on a single charge.

There are no internal expansion slots. It has no built-in floppy drive or hard disk, nor a standard cassette recorder interface. The external ports are an HP-IL interface, a serial port, and a phone connection for the internal 300 baud modem, which works with the built-in terminal emulator. The HP-IL interface is a two-wire, serial interface that can support up to 30 devices at once. Compatible devices include printers, the HP digital cassette drive, the HP-9114B battery-powered floppy drive, and various test equipment.
