Phunzirani Zakale Zodabwitsa za Chipangizo ndi Ntchito Yopanda Chidwi
HP 12c ndi yodabwitsa kwambiri m'moyo wake wonse ngati chipangizo chodziwika bwino cha akatswiri azachuma. M'nthaŵi yomwe zamagetsi monga mafoni a m'manja (mafoni a m'manja), makompyuta awo ndi zina zotero zikusintha mofulumira, chipangizo chotentha chotentha cha masiku ano chimakhala chosakhalitsa m'zaka zingapo. Izi zikupempherera osati kuti kampani yoyamba kugulitsidwa mu 1981 iyenera kukhala yopangidwa mpaka m'zaka za zana la 21, zaka zoposa 30 chiyambireni, komanso kuti idzapitirirabe kukhala golide wa akatswiri ochuluka pazinthu zamakono. amaimira msika womwe umalowera.
Kuitana Kwambiri
HP 12c Programmable Financial Calculator ili kusiyanitsa kutsogolera mankhwala onse a Hewlett-Packard mu chiwerengero cha zaka zopangidwa ndi chiwerengero cha mayunitsi ogulitsidwa. Malonda ogulitsa anadutsa 15 million unit mark mu 2007. Komanso, kudalirika kwamtundu wa HP 12c kumatanthauza kuti kupitirira kwakukulu kwa maguluwa kumakhalabe kugwiritsidwa ntchito, nthawi zina zaka 30 kapena kuposa zitangotenga.
Wokonzetsa izi wakhala akukonzekera kale ntchito zambiri zomwe zimapangidwira ntchito zomwe anthu omwe ali m'madera awa osiyana amayenera kugwiritsa ntchito mosalekeza:
- Owerengera ndi owerengera

Ili ndi mndandanda wa magawo omwe padera HP 12c ndi chida chamtengo wapatali.
Komanso, imagwira ntchitoyi mofulumira komanso mogwira mtima. Kuwonjezera pamenepo, HP 12c ikhoza kusunga mapulogalamu opangidwa ndi wogwiritsa ntchito.
Ngakhale kuti machitidwewa nthawi zambiri amalembedwa mosavuta ndipo amachitika pa makompyuta okhaokha, HP 12c imakhala yopindulitsa kwambiri pankhani imeneyi.
Sinthani Chiwerengero cha Polish
Kulowetsa deta ndi kuyendetsa makompyuta kumatsatira Mtsinje Wosinthika wa Polish (RPL), umene kwenikweni ndi mtundu wa chinenero cha makina kapena makompyuta. Ngakhale phokoso la arcane la msonkhano wogwira ntchito, zimakhala zophweka kwambiri kuphunzira kuchokera ku buku logwiritsa ntchito.
Chofunika kwambiri kuti muzindikire ndondomeko ya Maphunziro a ku Poland omwe akugwiritsidwa ntchito ndi HP 12c akuzoloŵera kulowa m'ntchito (monga kuwonjezera, kuchotsa, kuchulukitsa kapena kugawa) pambuyo pa operand, osati kale. Kuonjezera apo, atatha kuyika ntchito yoyamba pa chiwerengero chatsopano, wogwiritsa ntchito ayenera kukanikiza ENTER kuti afotokoze kuti chiwerengero chatsopano chayamba ndi kuti chiwerengero choyambirira chiyenera kuchotsedwa kuchokera ku zolembera.
Mwachitsanzo, kuwerengeka kosavuta 2 + 2 kungalowetsedwe ndi izi:
2 ENTER 2 +
Panthawiyi kuwonetsera kudzawerenga 4.
Kusiya zotsatirazi mu bukhu lowonetsera limapatsa wogwiritsa ntchito malemba ena. Ndipotu, kugwiritsiridwa ntchito kwasinthidwe ku Poland kumapangitsa HP 12c kukhala yabwino kupanga zovuta zowerengeka zomwe zidzasonyezedwe ndi kugwiritsiridwa ntchito kwambiri kwa makolo.
Kukhazikika, Kuchita Mphamvu ndi Mphamvu
HP 12c ikuyamikiridwa mwachilungamo chifukwa chakhazikika ndi kusokonezeka. Izi zinali zikuluzikulu pa kapangidwe koyambirira, ndipo kukhala ndi madontho akuluakulu kumalo okonzedwe kunayesedwa mwakuya musanayambe kutulutsa.
Kuwonjezera apo, HP 12c inalinganizidwa kuti ikhale yogwira mtima kwambiri, ndipo ntchito zenizeni zoposa zomwe zidalembedwa. Chitsanzo choyambirira chinali ndi mabatire atatu a kamera, ndipo bukuli linkagwiritsidwa ntchito moyenera kwa miyezi 6-12 (kapena maola 80-180 a pulogalamuyo ikuyenda), malingana ndi ngati amatha ma batiri kapena siliva okwera mtengo kwambiri. Wokambirana uyu ndi mmodzi mwa anthu ambiri omwe adanena kuti, ngakhale kuti ntchito yamagetsi yowirikiza tsiku ndi tsiku, kothamanga inathamanga zaka zoposa 10 asanayambe kusintha ma batri.
Mphamvu yamakono ya calculator yawasintha kukhala batri imodzi ya CR2032 lithium batri, koma mwachiwonekere, moyo wautali womwewo umakhala wokondweretsedwa ndi eni ake.
Mtengo wamtunduwu unagwa kuchokera pa $ 150 patsikuli mu 1981 (pafupifupi madola 256 mu 2012) mpaka $ 69.99 mu 2012.
Wokambirana uyu anagula $ 89 mu November 1987 (pafupifupi madola 178 mu 2012).
Fufuzani Ntchito
HP 12c ikhoza kugwiritsidwa ntchito ndi anthu omwe akuyesa mayeso ovuta awa:

Yerekezerani mitengo
Kuwongolera uku kumachokera ku HP 12c imene wolemba anagula mu 1987 ndipo akupitirizabe kugwiritsa ntchito lero.
