Emuva Esikhathini: Nakhu kuza i-VisiCalc, isofthiwe yoguquko yokwethula umphakathi ngekhompyutha

Abanikazi bamakhompyutha we-Apple okwamanje banenani lezinhlelo zokusebenza ezinhle kakhulu abanazo. Ekupheleni kweminyaka engamashumi ayisikhombisa ekhulwini elidlule, lapho ikhompuyutha ye-Apple II ibona ukukhanya kosuku, ukunikezwa kwesofthiwe kwaba mpofu kakhulu. Kodwa kungaleso sikhathi lapho kwavela khona i-VisiCalc - isofthiwe yesipredishithi eyagcina yenza isibotho emhlabeni.

Uhlelo olubizwa ngokuthi i-VisiCalc luvela eshabhu yeSoftware Arts, eyabe iqhutshwa osomabhizinisi uDan Bricklin noBob Frankston. Ngesikhathi bekhipha i-software yabo, amakhompyutha omuntu siqu ayengakabi ingxenye esobala yawo wonke amakhaya njengoba enjalo namuhla, futhi ayeyingxenye yezinto zezinkampani, amabhizinisi kanye nezikhungo. Kepha u-Apple - hhayi u-Apple kuphela - kudala ezama ukuguqula lesi simo. Kwaba ukukhishwa kwe-VisiCalc okulethe amakhompyutha omuntu eduze kancane nesizinda somsebenzisi esibanzi, futhi lokho kwashintsha indlela le mishini eyayibonwa ngayo iningi labantu abavamile ngaleso sikhathi.

Nakuba ngesikhathi sokukhishwa kwayo, i-VisiCalc yayingafani neze namaspredishithi anamuhla - kungaba emisebenzini yawo, izilawuli noma isixhumi esibonakalayo somsebenzisi - yayibhekwa njengesofthiwe eqanjwe kakhulu futhi ethuthuke kakhulu yohlobo lwayo. Kuze kube manje, abasebenzisi babengenalo ithuba lokusebenzisa izinhlelo zalolu hlobo kumakhompyutha abo, ngakho-ke i-VisiCalc yaba i-hit enkulu ngokushesha. Phakathi neminyaka eyisithupha yokuqala yokukhululwa kwayo, yakwazi ukuthengisa amakhophi ahloniphekile angu-700, naphezu kwentengo ephakeme kakhulu, ngaleso sikhathi eyayifinyelela kumadola ayikhulu ncamashi. Ekuqaleni, i-VisiCalc yayitholakala kuphela enguqulweni yamakhompiyutha e-Apple II, futhi ukuba khona kwalolu hlelo kwaba isizathu sokuthi abasebenzisi abangaphezu koyedwa bathenge lo mshini ngamadola ayizinkulungwane ezimbili.

Ngokuhamba kwesikhathi, i-VisiCalc iphinde yabona izinguqulo zamanye amapulatifomu ekhompyutha. Ngaleso sikhathi, ukuncintisana ngendlela ye-Lotus 1-2-3 noma izinhlelo ze-Excel ezivela ku-Microsoft zase ziqalile ukunyathela ezithendeni zayo, kodwa akekho ongaphika ubuholi beVisiCalc kule ndawo, njengoba nje kungenakuphikwa ukuthi uma hhayi i-VisiCalc, isofthiwe encintisanayo eshiwo ngenhla cishe ngeke ivele, noma ukuthuthukiswa nokuvela kwayo kungathatha isikhathi eside kakhulu. I-Apple, ngokungangabazeki, ingabonga abadali be-software ye-VisiCalc ngokukhula kokuthengiswa kwekhompyutha ye-Apple II.
