The '''Sharp PC-1211''' is the first [[pocket computer]] ever released, marketed by [[Sharp Corporation]] in March 1980.<ref name=cw>{{cite journal | last=Hayes | first=Frank | date=December 16, 2002 | url=https://www.proquest.com/docview/216103610/ | title=The Story So Far | work=Computerworld | publisher=IDG Publications | volume=36 | issue=51 | page=28 | via=the Internet Archive}}</ref><ref>{{cite journal | last=Barry | first=John | date=September 1, 1980 | url=https://books.google.com/books?id=az4EAAAAMBAJ&pg=PT65 | title=Japanese Retailer Pursues U.S. Market | work=InfoWorld | publisher=IDG Publications | volume=2 | issue=15 | pages=26–27 | via=Google Books}}</ref> The computer was powered by two [[4-bit computing|4-bit]] [[CPU]]s laid out in power-saving [[CMOS]] circuitry. One acted as the main CPU, the other dealt with the input/output and display interface. Users could write [[computer program]]s in [[BASIC]].

A [[badge-engineered]] version of the PC-1211, the '''TRS-80 Pocket Computer''' (model '''PC-1'''), was marketed by [[Radio Shack]] in July 1980 as the first iteration of the [[TRS-80]] Pocket Computer with just a marginally different look (outer plastic parts in black, not brown, gray display frame)

==Technical specifications==
*24 digit [[dot matrix]] [[LCD]]
*Full [[QWERTY]]-style keyboard
*Integrated beeper
*Connector for printer and tape drive
*Programmable in [[BASIC]]
*Uses four [[MR44]] {{val|1.35|ul=V}} Mercury button cells
*Battery life in excess of 200 hours
*1424 program steps, 26 permanent variable locations ({{mono|A}}-{{mono|Z}} or {{mono|A$}}-{{mono|Z$}}) and 178 variables shared with program steps
*Built out of off-the-shelf [[CMOS]] components, including SC43177/SC43178 processors at {{val|256|ul=kHz}} and three TC5514P {{val|4|u=[[kilobit|Kbit]]}} RAM modules

===Accessories===
*CE-121 Cassette Interface

A [[badge-engineered]] version of the Sharp PC-1211 was introduced in July 1980 and marketed by [[Radio Shack]] as the original TRS-80 Pocket Computer. This was later referred to as the "PC-1" to differentiate it from subsequent entries (PC-2 onwards) in the [[TRS-80 Pocket Computer line]].<ref name='oc_pc1'>{{cite web|url=https://www.old-computers.com/museum/computer.asp?c=937&st=1|accessdate=2015-03-05|quote=Nowadays, it is often referred to as the TRS-80 PC-1, so as to differentiate it from its successor, the TRS-80 PC-2 (and following)|title=TRS 80 PC-1|publisher=old-computers.com}}</ref>
