Notes
The Rev. 2 iMacs included 6 MB of VRAM standard, allowing for 24 bit color
at 1024x768.
Announced in May 1998 and shipped in August, the iMac was Apple's computer
for the new millennium. Aimed at the low-end consumer market and designed
with the internet in mind, the iMac was positioned by Apple as the most
original new computer since the original Mac in 1984, and came in a
stylish new case design, with translucent "Bondi Blue" plastics. The iMac
included a 4 Mbps IrDA port, and an internal 56Kpbs modem (a 33.6 kbps
modem was originally announced in May, but was upped to 56 kbps at
MacWorld.), used two 12 Mbps Universal Serial Ports (USB) as its only
means of external expansion, and included a newly-designed USB keyboard
and mouse. While it had no other serial or SCSI ports, many manufacturers
promised to make a variety of USB peripherals available by the time it
shipped in August, and by and large they delivered on that promise. A "Rev
B." model was released several months later, with 6 MB of VRAM, and
several hardware bug-fixes. The iMac sold for $1,299. This Rev. B iMac was
replaced by the Rev. C in January 1999. |
