    "description": "The Casio PB-1000 was an original, well designed and powerful pocket computer for its time. \nOn top of its standard QWERTY keyboard, a row of sensitive keys allowed fast \nscientific calculations, menus access and text editing. The 4-line LCD display \nalso had 16 sensitive areas.\nThe computer could be programmed either in Basic or Assembly language. The C61 Basic interpreter, based on Japan Industrial Standard BASIC, had a wide range of built-in mathematic, trigonometric and statistic functions. Assembly programs had to be typed by using the built-in editor then compiled. The user's manual gave little information about CPU instructions and, oddly enough, Casio and it's distributors never released a full description of the whole CPU's instructions set, although Casio published an incomplete \"Technical Reference Manual\".\nThe processor was an Hitachi HDS61700. It contained a small amount of ROM and RAM, as well memory management and I/O circuitry. The memory was managed like a virtual disk. Several Basic or Assembly programs as well as ASCII text could be stored together in the same RAM area.\nTwo extensions were released for the PB-1000, the FA-7 Serial, Parallel and tape recorder interface, and the rare MD-100 3.5\" floppy drive unit.\nThe PB-1000 was followed by the <b>PB-2000</b> which lost the lift up display but had the unique feature of being programmable in ANSI C language.",
