Amaya Toman Kwakusekuqaleni kukaFebhuwari 1979, futhi osomabhizinisi uDan Bricklin noBob Frankston basungula inkampani yabo iSoftware Arts, eyashicilela uhlelo oluncane lweVisiCalc. Njengoba kuzobonakala kamuva, ukubaluleka kwe-VisiCalc emaqenjini amaningi ekugcineni kwaba kukhulu kunalokho okungenzeka ukuthi abadali bayo bebekulindele ekuqaleni.
Kungaba njalo okuthakaselayo
Kubantu “abakhule” benama-PC nama-Mac emsebenzini, kungase kubonakale kungenangqondo ukuthi kunesikhathi lapho kwakunomehluko wangempela phakathi kwamakhompyutha “omsebenzi” kanye “nasekhaya,” ngaphandle kwesoftware esetshenziswa imishini. Ezinsukwini zokuqala zama-computer omuntu siqu, osomabhizinisi abaningi babewabheka njengemishini yokuzilibazisa eyayingenakuqhathaniswa nemishini eyayisetshenziswa izinkampani ngaleso sikhathi.
Ngobuchwepheshe, kwakungenjalo, kodwa abantu abahlakaniphile babona ukuthi iphupho lekhompyutha eyodwa lalifeza injongo ehlukile kumuntu ngamunye. Ngokwesibonelo, amakhompyutha omuntu siqu afinyeza amasonto isisebenzi okungase kudingeke silinde umnyango wamakhompyutha wenkampani yaso ukuze silungise umbiko. I-VisiCalc ingenye yezinhlelo ezasiza ekuguquleni indlela abantu abaningi ababebuka ngayo amakhompyutha "okungewona awebhizinisi" ngeminyaka yawo-70 - yabonisa ukuthi ngisho namakhompyutha omuntu siqu njenge-Apple II angaba ngaphezu kwethoyizi "elingenangqondo" leqembu elithile lezithameli eziqondiwe. .
Igalari yezithombe
Uhlelo olusha lwesipredishithi i-VisiCalc yathatha njengesingathekiso salo umbono webhodi lokuhlela ukukhiqiza ebhizinisini, elingasetshenziselwa izengezo nokubalwa kwezimali. Ukudala amafomula kwakusho ukuthi ukushintsha inani leseli elilodwa lethebula kuzoshintsha izinombolo kwelinye. Nakuba namuhla sinamaspredishithi amaningi ahlukene esingakhetha kuwo, ngaleso sikhathi lwalungekho uhlelo olunjalo. Ngakho-ke kuyaqondakala ukuthi i-VisiCalc ibe yimpumelelo enkulu.
I-VisiCalc ye-Apple II ithengise amakhophi angu-700 eminyakeni eyisithupha, futhi cishe amakhophi ayisigidi esikhathini sokuphila kwayo. Nakuba uhlelo ngokwalo lubiza u-$000, amakhasimende amaningi athenge amakhompyutha we-Apple II angu-$100 ukuze nje aqhube uhlelo kuwo. Akuphelanga sikhathi esingakanani ngaphambi kokuthi i-VisiCalc ithuthwe nakwamanye amapulatifomu. Ngokuhamba kwesikhathi, kwavela amaspredishithi aqhudelanayo afana ne-Lotus 2-000-1 ne-Microsoft Excel. Ngesikhathi esifanayo, zombili lezi zinhlelo zathuthukisa izici ezithile ze-VisiCalc, kusukela endaweni yokubuka yezobuchwepheshe noma endaweni yokubuka yomsebenzisi.
