The HP Palmtop Family
In production: 1991-1999
The
HP 95LX (Lotus Expandable) was introduced in 1991. It was the first personal computer that you could carry in your pocket or purse. With its "blue keys" it let you keep track of appointments, to-do's, and phonebook entries. For business mathematicians, it featured a numeric keypad along with an upgraded version of the HP 19B II advanced business calculator, called HP Calc, and the piece de resistance, a relatively full version of Lotus 1-2-3. All the applications were in 1 MByte of ROM and were made accessible through the System Manager shell program. For a CPU it used the NEC V20 H, an Intel 8088 equivalent, operating at 4.77 MHz. The original HP 95LX came with 512K bytes of RAM. The second release of the Palmtop boosted this to 1Mbyte. It had a PC Card slot that could handle Type 1 RAM cards and battery supported, flash memory cards. The serial port could connect the Palmtop to an external modem, a serial printer or a desktop PC. For an operating system it used MS-DOS 3.22. Many programs were written for this machine, however, the biggest challenge was trying to get standard DOS programs to run on its 40X16 text mode screen.
