Macintosh IIcx & IIci: 5.25-Inch Internal Hard Disk Installation



I want to purchase third-party (MicroNet) 5.25-inch hard disks with special
mounting brackets for my Macintosh IIcx and Macintosh IIci systems.

1) What is Apple's position about using 5.25-inch drives in the Macintosh
IIcx or Macintosh IIci?

2) Will these drives draw too much power?

1) Apple's position is that the installation and use of an internal
5.25-inch hard disk in a Macintosh IIcx or Macintosh IIci voids the
warranty of the computer.

2) An internal hard disk may draw 1 amp (5 watts) on the +5V line and .5
amps (6 watts) on the +12V line. On startup, a surge of 1.5 amps (18
watts) for 15 seconds is allowable on the +12V line. No surge is allowed
on the +5V line.
