TheSharp PC-5000 was a pioneeringlaptopcomputer, announced bySharp Corporation ofJapan in November 1983.^[1][2][3] It employed aclamshell design in which the display closes over the keyboard, like the earlierGRiD Compass and contemporaryGavilan SC.

The PC-5000 was largelyIBM PC-compatible, with the same 4.77-MHzIntel 8088processor as the IBM PC, and ranMS-DOS 2.0 (inROM). It had 128kilobytes of internalmemory (it was one of the few computers to usebubble memory), which could be expanded by the use of plug-in cartridges. The cartridge slots also accepted ROM cartridges containing software, such as the ExtendedBASICprogramming language and the EasyPac software suite, which contained the EasyWrite IIword processor, EasyReport reports program, and EasyComm terminal software for use with the internalmodem. It featured a 640×80-pixel (80-character by 8-line)LCD display, a full-travelkeyboard, and an external dual 5.25-inchfloppy disk drive. A notable feature of the computer was its built-inthermal printer, which could also be purchased separately and attached to the machine. It is perhaps due to this attachment that the case design of the PC-5000 owes much to that of electronic typewriters of its time.

While far more portable than the popularCompaq Portable orOsborne 1 computers, the machine weighed 5kg (11 lb).

Sharp succeeded the PC-5000 with the fully IBM-compatiblePC-7000 in late 1985.^[4]

Your Computer magazine selected the PC-5000 as one of the best personal computers of 1983.^[5]Creative Computing chose the PC-5000 as the best notebook portable between $1,000 and $2,500 for 1984, although criticizing the difficulty of finding the computer in stores and questionable support from Sharp and third-party vendors.^[6]
