The Sharp PC-5000 was a pioneering laptop … The Sharp PC-5000 was a pioneering laptop computer, announced by Sharp Corporation of Japan in November 1983. It employed a clamshell design in which the display closes over the keyboard, like the earlier GRiD Compass and contemporary Gavilan SC. The PC-5000 was largely IBM PC-compatible, with the same 4.77-MHz Intel 8088 processor as the IBM PC, and ran MS-DOS 2.0 (in ROM). It had 128 kilobytes of internal memory (it was one of the few computers to use bubble memory), which could be expanded by the use of plug-in cartridges. The cartridge slots also accepted ROM cartridges containing software, such as the Extended BASIC programming language and the EasyPac software suite, which contained the EasyWrite II word processor, EasyReport reports program, and EasyComm terminal software for use with the internal modem. It featured a 640×80-pixel (80-character by 8-line) LCD display, a full-travel keyboard, and an external dual 5.25-inch floppy disk drive. A notable feature of the computer was its built-in thermal 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 popular Compaq Portable or Osborne 1 computers, the machine weighed 5 kg (11 lb). Sharp succeeded the PC-5000 with the fully IBM-compatible PC-7000 in late 1985.fully IBM-compatible PC-7000 in late 1985.

Come il , che lo precedeva, ed il contemporaneo , impiegava un design a "libro" in cui il video si chiudeva sopra la tastiera. Il PC-5000 era quasi completamente compatibile con l'IBM PC. Utilizzava infatti lo stesso processore Intel 8088 a 4.77-MHz ed eseguiva MS-DOS 2.0 (in ROM). Aveva 128 kilobyte di (era uno dei pochi computer ad utilizzare la memoria a bolle), che poteva essere espansa attraverso l'inserimento di cartucce. Gli slot per le cartucce accettavano anche cartucce ROM contenenti software, come il linguaggio di programmazione Extended BASIC e la suite software EasyPac. Quest'ultima conteneva il word processor II, il programma per realizzare report EasyReport, ed il software per terminale EasyComm che era stato concepito per poter essere usato con il modem interno. Era caratterizzato dall'avere un display a cristalli liquidi (LCD) da 640×80-pixel (80-caratteri per 8-linee), una tastiera con tasti a corsa completa, ed un floppy disk drive esterno doppio da 5.25-pollici. Una caratteristica distintiva del computer era la sua opzionale che doveva essere montata nel corpo stesso della macchina. È forse dovuto a questo componente incorporato che il design dell'involucro del PC-5000 assomiglia molto a quello delle macchine da scrivere elettroniche dell'epoca. Il computer era più facilmente "portabile/trasportabile" dei popolari computer od Osborne 1, anche se la macchina pesava ben 5 kg (11 lb).he se la macchina pesava ben 5 kg (11 lb).
