Emuva esikhathini esidlule: Isibani sika-Edison kanye ne-Powerbook 100 (21/10/2020)

Engxenyeni yanamuhla yochungechunge lwethu lwezehlakalo ezibalulekile emkhakheni wezobuchwepheshe, sizophinda sikhumbule isikhumbuzo esihlobene nenkampani i-Apple ngemuva kwesikhathi esithile. Namuhla usuku lwesikhumbuzo sokwethulwa kwe-Powebook 100. Kodwa sizobe sikhuluma ngelambu lokukhanyisa lika-Thomas A. Edison noma ilungelo lobunikazi lenkumbulo ye-ferrite.

Isibani sikaThomas A. Edison (1879)

I-Powerbook ka-Apple (1991)

Ngomhla zingama-21 kuMfumfu, 1991, i-Apple yethula i-laptop yayo ephathekayo ebizwa ngokuthi i-Powerbook 100.

I-Powerbook 100 notebook ifakwe iphrosesa engu-16MHz Motorola 68000 futhi ifakwe imonitha ye-Matrix LCD engamayintshi ayisishiyagalolunye ye-monochrome. I-PowerBook-noma kunalokho wonke umugqa womkhiqizo-yamukelwe kahle ngokumangazayo ngabasebenzisi, yazuza i-Apple ngaphezulu kwe- $ XNUMX billion ngonyaka wayo wokuqala.
