How To Open A Classic Mac
Opening Compact Macs like the Mac Plus or SE/30 is relatively
easy. You need two simple tools: a T-15 Torx screwdriver with a
long
shank and a 1" spring clamp.
The best place to get the T-15 Torx screwdriver here is the states
is Sears. The Sears T-15 part number is 47431 and it's part of
the
Craftsman Professional line (Craftsman Professional tools have a
black handle). You can also get a T-15 Torx screwdriver with an
11"
shank from McMaster-Carr (a large US supply company); the part number
for the 11" Torx T-15 is 5756A56. McMaster-Carr's web
site requires Java for its search engine, so if you want to call in
an order, call (630) 833-0300 (Chicago).
What's the spring clamp for? Mac Guru Larry Pina suggests using a
1" spring clamp as a case spreader. They're available at any
hardware store, etc - just ask for a spring clamp (sometimes they're
also called "pony" clamps). When you get the clamp, take the
rubber protectors off the clamping jaws (so you can get the jaws into
the groove of the Mac).
For the actual "take apart", the Mac 128k, 512k, 512ke, and Mac
Plus have FIVE screws on the back of the unit: two at the bottom,
two inside the handle and one behind the battery (the battery
compartment is on the upper right side of the rear). All other
compact
Macs only have four screws (there is no external battery
compartment).
Once you have the screws out, put the jaws of the
spring-clamp-turned-case-spreader in the groove and gently squeeze
the clamp. Pina
also suggests moving along the entire groove with the spreader so you
don't "chew up" the groove. Pina has a good reputation and
he's right - it does work.
WARNING: Once you open the Mac, you can be exposed to high
voltages from the CRT (screen). ALWAYS unplug your Mac when
working inside. To minimize the risk of High Voltages, it is
advisable to leave your Mac turned off overnight. You must be
VERY
CAREFUL around these voltages. I assume no liability for your safety
while working inside your Mac.
