夏普PC-1501袖珍计算机的检修夏普PC-1501袖珍计算机的检修某日在广播论坛闲逛，看到天津的朋友转让一套PC-1500。
由于关注此机已久早有收入囊中之意，所以赶紧喊出标准语我要了，代价是只要45米还包邮。
收到机器后发现该机比想象的要大。
原本印象中只是普通计算器，看到实物才觉得确有些Pocket Computer的味道。
现将近几日的把玩情况和收集资料与大家作些分享。
Sharp PC-1500是上世纪80年代初由夏普公司推出的袖珍计算机。
网上有评论是：“论资历，它比IBM PC普及得更早；论体积，当今大多数便携机也仍不是它的对手；论年龄，它比当代部分IT精英出生得更早。
是极具收藏价值的计算机。
” 其原本的辉煌可见一斑，当年国内的不少企、事业单位都购置了该机，尤其是在石油、气象、测绘、地质勘探等部门更是应用广泛。
该机型一共推出了三个型号：PC-1500，PC-1500A，PC-1501，除有微小区别外均是大同小异。
该机的出生年代正好与IBM PC机同年，但其价格和便携性显然都比IBM PC更具有优势，所以普及速度要比PC更快。
但只是其处理能力和应用场景是远不及PC，进而渐渐被市场所淘汰。
现今的机器多是留给一些计算器爱好者在收藏。
过去本人无幸接触此类机器。
只记得上大学的当年，班上同学有海外亲戚从国外带回一台计算器都让我们感到非常的神奇。
后来学习了ALGOL60语言，让我一下就喜欢上计算机这玩艺为将来的发展打下基础。
在学校的计算中心上过DJS-130机，顺利的编过一些程序。
再后来写毕业论文也是在TQ-16机上用ALGOL60语言编程实现最优路径的查找。
清楚的记得当学习校的DJS-130机不能用时，还从系里特批经费去一个设计院的计算中心在其TQ-16机上调试相关程序。
当时上机费用为60元/小时，这可是30年前的人民币啊！一、主要参数：微处理器：LH5801 8位CMOS集成芯片，指令兼容Z80，主频1.3MHz存储器：ROM 16KBRAM 3.5KB（PC-1500）/8.5KB（PC-1500A，PC-1501）程序语言：BASIC、汇编语言计算位数：10位有效数字加2位指数。
Important NoteThis is the refreshed model, updated with 48V external battery. Extra runtime is available by connecting up to four optional extended battery modules BP48VRM2U (sold separately).SmartPro 1440VA 1440W 120V Line-Interactive Sine Wave UPS - 8 Outlets, Extended Run, Network Card Option, LCD, USB, DB9, 2URack/TowerMODEL NUMBER:SMART1500RMXL2UProvides complete battery backup and pure sine wave power output for servers, switches and other high-end distributed IT equipment.Features1.44kVA/1.44kW/120V Battery Backup for Distributed IT, Telecom or Enterprise DeploymentsThis rack-mount line-interactive UPS system provides reliable battery backup and AC power protection against blackouts, brownouts, surges and line noise that can damage your valuable IT equipment or destroy data. The SMART1500RMXL2U is ideal power management for high-end in-rack networking equipment, including servers, VoIP phones, data storage and PoE switches. Unity power factor ensures the most watts possible at each power rating, so you can connect more equipment.Reliable, Expandable Battery Backup Keeps You Operational Through Power OutagesThe field-replaceable, hot-swappable VRLA battery modules allow you to work through short power failures and give you enough time to safely save files and shut down your system in case of a prolonged blackout. Switchover from line to battery power happens within milliseconds to maintain continuous operation of connected equipment without interruption or rebooting. Extra runtime is available by connecting up to four optional extended battery modules (BP48VRM2U, sold separately).Optional LX Platform Network Management Card Allows Remote Access 24/7The WEBCARDLXE network interface (sold separately) enables full remote configuration and management, including load shedding, reboots of connected equipment and safe shutdowns. The IP-based Auto Probe feature ensures continuous network uptime by communicating with other network devices, detecting lost connectivity and automatically rebooting IT equipment. Optional EnviroSense2 modules (E2MT, E2MTDO and E2MTHDI, all sold separately) provide a variety of environmental monitoring and control options.NEMA 5-15R Outlets Protect Your Connected Components HighlightsProtects equipment againstblackouts, brownouts, transientsurges and line noiseqKeeps equipment running during outages to allow time for filesaves and safe shutdownqUnity power factor ensuresmaximum power possible ateach power ratingqENERGY STAR 2.0-certified tosave electricity, lower costs andprotect the environmentq2-line front-panel LCD with 10selectable screens reportsdetailed UPS and site powerinfoqFor remote monitor and control,the WEBCARDLXE is required(sold separately).

Power provided by these outlets is filtered to protect connected equipment against damaging surges and line noise. Four outlets are grouped into two programmable load banks that let you shed non-critical loads to extend runtime for critical loads. Front and rear cooling fans help protect equipment from overheating.Automatic Voltage Regulation (AVR) Corrects Low- and High-Voltage ConditionsAVR protects your equipment from incremental hardware damage, data loss and performance problems caused by brownouts. The SMART1500RMXL2U maintains regulated 120V nominal output duringbrownouts and overvoltages from 80V to 151V while keeping the battery fully charged and ready to take over in case of power failure.Premium Protection from EMI/RFI Line Noise Helps Your Equipment Perform BetterThis UPS system filters out disruptive electromagnetic and radio frequency interference that can inflict hardware damage or data loss. This EMI/RFI filtering also helps your connected components perform better and last longer.ENERGY STAR-Certified to Help You Save Money and Protect the EnvironmentBy meeting strict U.S. Department of Energy and U.S. Environmental Protection Agency requirements,this ENERGY STAR 2.0 UPS system provides high operational efficiency to signal a reduction in BTU emissions, save on utility and cooling costs and help protect the environment.Intuitive Front-Panel Interface for Convenient UPS Operation and MonitoringThe two-line front-panel LCD monitoring screen features 10 selectable screens that allow quick access to a wide range of detailed UPS and site power information. LEDs show UPS status: a green light means utility power is on, an orange light means the UPS is in battery mode and a red light indicates an active alarm or fault. The control panel rotates to accommodate both rack-mount and tower configurations.Advanced Communications Ports Allow for Automatic Saves and ShutdownsRS-232 and USB ports connect to a device for a variety of communication options (cables are included). A dry-contact relay port can be programmed through the LCD to provide reliable communications to automation and industrial components.
