iMac G3: Design

From any previous mainstream computer the iMac G3, was dramatically different. it was made up of translucent Bondi blue color. it was egg shaped, colored plastic and around a 15 inch CRT display. there was the handle and the peripheral connected in the case.

the connectors were actually hidden behind the door on the right hand side of the machine. the complemented built-in stereo speakers were present in the dual headphone jack in the front.

The original designer of this product was Den Acosta and Jonathan Ive. The color options and unique shape of iMac G3 held in gained itself into late 1990s pop culture. This Mac was actually the first computer which offered USB ports and also included the connector for its new mouse and keyboard that made a bend in the previous Macintosh peripheral connections like SCSI, Geoport serial port, and ADB. 

one of the good steps in this iMac G3 was abandoning the 3.5 inch floppy disc drive. Apple also argued that the internet, recordable CDs, and office network were quickly making diskettes obsolete.

 When the iMac G3 was introduced the third-party manufacturers also offered floppy disk drivers and external USB, that is often in translucent plastic to match the iMac enclosure.

The components like tray loading CD-ROM and front mounted irDA port which borrowed from Apple laptop line.

but this match did not officially have expansion slowed the first version had the slot that was dubbed in mezzanine slot it was only for Apple internal use. The mouse and the keyboard were also redesigned for this iMac, with translucent plastic and a Bondi blue trim.

In comparison with Apple’s previous keyboard the Apple USB keyboard was smaller in size and got white characters on the black keys and boards were the attributes that attracted debate. As for the apple’s USB mouse it was mechanical and of a round hockey puck design. it was unnecessarily difficult for users with large hands. 

After some time Apple introduced a new capsule shaped optical mouse that was known as apple Pro mouse and later renamed as apple Mouse it actually replaced the round mouse across all of Apple hardware offerings.

 it has 512 KB L2 cache running at 116.6 MHz also ran in Apple’s high end Mac its speed was high and, shipped with Mac OS 8.1, which was then soon upgraded to makeover 8.5.

 The iMac G3 officially did not have an expansion slot as for the first version does load dubbed the mezzanine slot. It was only for Apple for internal use. all of your third party expansion cards are also released for a Voodoo II video card upgraded from 3dfx and SCSI-TV  tuner cards from the German company formac.
