Editing Zilog Z80 (section)

=== Portable and handheld computers ===
Use of the Z80 in lighter, battery-operated devices became more widespread with the availability of CMOS versions of the processor. It also inspired the development of other CMOS based processors, such as the LH5801<ref>{{Cite web |title=Sharp PC-1500 Technical Reference Manual |url=https://www.pc-1500.info/Data/Service_Manuals/PC-1500_Technical_Reference_Manual.pdf |url-status=live |archive-url=https://web.archive.org/web/20231105135940/http://www.pc-1500.info/Data/Service_Manuals/PC-1500_Technical_Reference_Manual.pdf |archive-date=November 5, 2023}}</ref> from Sharp. The [[Sharp PC-1500]], a [[BASIC]]-programmable [[pocket computer]] was released in 1981, followed by the improved [[Sharp PC-1600]] in 1986 and the [[Sharp PC-E220]] in 1991. Later models of the [[Sharp Wizard]] series of personal organizers also were Z80 based. [[Laptop]]s which could run the CP/M operating system just like the desktop machines followed with [[Epson PX-8 Geneva]] in 1984, and in 1985 the [[Epson PX-4]] and [[Bondwell-2]]. While the laptop market in subsequent years moved to more powerful [[Intel 8086]] processors and the MS-DOS operating system, light-weight Z80-based systems with a longer battery life were still being introduced, such as the [[Cambridge Z88]] in 1988 and the [[Amstrad NC100]] in 1992. The Z80-derived [[Zilog Z180|Z8S180]] also found its way into an early [[pen computing|pen-operated]] [[personal digital assistant]], the [[PenPad#PDA600|Amstrad PenPad PDA600]] in 1993. Hong Kong-based [[VTech]] produced a line of small laptop computers called 'Lasers' based on a Z80.<ref>{{Cite web |date=April 1991 |title=Poor Man's Laptop |url=https://books.google.com/books?id=0eQDAAAAMBAJ&q=laser+pc4&pg=PA120 |access-date=April 11, 2018 |website=Google Books |publisher=Popular Mechanics, April 1991, page 120}}</ref><ref>{{Cite web |title=Laser PC4 |url=https://www.oldcomputermuseum.com/laser_pc4.html |url-status=live |archive-url=https://web.archive.org/web/20231105135941/http://www.oldcomputermuseum.com/laser_pc4.html |archive-date=November 5, 2023 |access-date=April 11, 2018 |website=Old Computer Museum}}</ref> The last two were the Laser PC5<ref>{{Cite web |title=Laser PC5 from VTech |url=https://www.larwe.com/museum/laserpc5.html |url-status=live |archive-url=https://web.archive.org/web/20231105135939/http://www.larwe.com/museum/laserpc5.html |archive-date=November 5, 2023 |access-date=April 11, 2018 |website=larwe.com}}</ref> and PC6.<ref>{{Cite web |title=Laser PC6 |url=http://www.perfectsolutions.com/pc6f.asp |url-status=dead |archive-url=https://web.archive.org/web/20180521024606/http://www.perfectsolutions.com/pc6f.asp |archive-date=May 21, 2018 |access-date=April 11, 2018 |website=Perfect Solutions dot com |publisher=Perfect Solutions}}</ref>
