    Powerbook 3400c Logic Board Help

    I have a pair of 3400c machines each with a different issue. The first machine shows artifacts around the mouse pointer and usually corrupts the display of text and video game graphics and the second works perfectly for a while but then the backlight shuts off on the display and stays off. The machine is still running fine and I can shut it down and then if I wait a bit and boot it up again sometimes the backlight is back to working. I had thought the issue with the backlight was probably an inverter issue so yesterday I swapped the logic boards between the two machines and, what do you know? The backlight issue followed. It's something on the logic board. Anybody got any advice to find the cause of either issue? If I can fix at least one of the logic boards I'll be happy. Are there caps I could replace? FWIW, both boards look fantastic. No obvious corrosion or leakage anywhere. I've reset the PMU, put in a fresh PRAM battery and the original battery is still holding a charge (astonishingly). The machine with the video problem is a 180 and the machine with the backlight problem is a 240. Thanks in advance for any pointers you can provide.

    Source for PB1x0 battery pack cases?

    I've got a few around. I have been thinking about doing a 3D scan of the case for 3D printing. I've repacked one and there is no smart circuitry in there, just batteries and a couple thermal fuses. Has anybody got 3D printable files of old Mac parts? Is there a resource somewhere?

    Working Powerbook 3400c for $48

    Oh, and one more thing... I also scored a NOS Asante Micro EN/SC, unopened in the original box, a couple weeks ago to get my PB 180 online. Works perfectly. I've paired it up with an IOGear Ethernet-To-WIFI adapter powered by a battery pack to make my PB 180 into a fully wireless, internet connected, beast.

    Working Powerbook 3400c for $48

    I bought a PB 3400c in "untested, as-is" condition on eBay, brought it home, plugged it into a working power supply and discovered it was completely functional except for the usual need for a new PRAM battery and a battery pack rebuild. I've ordered the PRAM battery and some fresh 26650 Li-Ion cells for the pack rebuild. Score!
  5. Hey gang, It's been years since I was last marching with the 68kMLA but after some time foolishly spent not toying around with 68k Macs I found that I missed my old Powerbook 170 too much and succumbed to the charms of a Powerbook 180 on Craigslist. When I first got the 180 the screen was starting to show tunnel vision and, fortunately, I was able to find a new screen that does not have the problem but I got to thinking... Are there any replacement screens on the market today that could be purchased brand new to give new life to these old active-matrix Powerbooks? I've been searching the internet hoping to find an answer and so far it seems that nobody has offered up either a) a supplier who still sells the original LCD or b) a new compatible replacement alternative. Anybody got any pointers? We are rapidly running out of Powerbook 170's and 180's and I kind of feel a personal mission to find a solution to this. Thanks in advance!
