Hello, when I start a newly acquired Powerbook 180 everything is great. After about 20 minutes or so it a single Pixel in the lower third of the screen stays black. When I turn the machine off and wait for an hour or so, then start it back up, the pixel is normal. Has anyone here seen something...

Hi, a beautiful PB 180 has come into my possession. No tunneling (yet. It's been running about an hour. Fingers xed). However, the CCFL is a bit on the weak side. Would anyone here know whether the same tubes are used throughout the 1xx (140, 145, 160, 165, 180) line, or are they different? The...

Hello, I am renovating a powerbook 160. Its screen has been recapped and works well. The battery is dead; I‘m rebuilding it to house 5 x 1.2 V 700 mAh NiCd cells (which means it won‘t last long but I hope it‘ll last a few minutes). The PRAM battery is also probably dead (date and time, AppleTalk...
