How do I add RAM to an LCIII?

uh, i think there are only two slots. It is very easy, Lift up the back cover and go ahead.No need for matched pairs.

 

Yes, 72 pin SIMMs are installed in pairs

The easy way (and the only way I know of) is to lift on the two thumb tabs on the back-top of the case and rotate the upper case forward and off. You'll have full access to the logic board, which should be pretty simple in it's layout.

The one thing you should remember is that these systems need to have the logic board reset after installing RAM. I don't recall if the LCIII has a reset button, but unplugging the system and removing the battery for about 30 seconds should do the trick.

 

Errr.. you sure we talking about the same machine?

The LC III has ONE memory socket. It has a maximum of 36 Mb RAM (4 Mb built in, plus a 32 Mb 72-pin SIMM.

Mandatory matched pairs with 72-pin RAM didn't reappear until the PowerMac 6100/7100/8100 machines IIRC. The larger Quadras could take advantage of matched pairs but it wasn't forced.

You're right... I was thinking of the logic board in the LCII while remembering that the LCIII used the 72 pin SIMMs.

Good catch!

 

36 megs of ram... Don't spend it all at once!
