Half a year following the release of the Macintosh IIx
passed before Apple
introduced the Macintosh IIcx
in 1989. Despite resembling the IIx to a great extent, the IIcx was quieter (due to its quieter fan on a smaller power supply) than its predecessor. The design was also much more compact because it had only three NuBus
slots. The new case, Apple's only to be designed to operate in either horizontal or vertical orientation, remained in use for its successors the IIci
and Quadra 700
. The idea for vertical orientation, one of the first minitower
cases, was suggested by Apple CEO John Sculley
, who was running out of space on his desk.
Users liked the Mac IIcx in part because its components and parts (such as RAM, NuBus slots, and power supply) snapped into place case without the need for screws. At the IIcx's introduction, Jean-Louis Gassee demonstrated the IIcx's modular design by assembling one from parts in front of the audience This made it less expensive to build, easier to repair, and earned it heavy praise and a warm reception amongst the Mac community.
This model was superseded by the Macintosh IIci.
