OK,
Last night I installed the new RAM, according to the Apple instructions. Easy.
Booted it up and checked the "About this Mac".
Memory now is 384 MB! The computer seemed to be running just fine.
BUT this morning my daughter left me a note saying her iChat was freaking out.
Well, since she was still asleep by the time I had to leave for work I couldn't quiz her.
Was she loosing her modem connection, or was iChat freezing?
We'll see tonight when I get back home.
If nothing else, I can swap the memory back and see if that fixes the problem.
Oh yes, the memory I bought was from Best Buy last weekend. It's K-Byte RAM (new). With the $20 rebate it cost $30. A very good price for 256 MB.
Stay tuned!
