    Getting my SE/30 online

    Correction and update: In TCP, I'm NOT using the "Manual" setting but the "Server" one (middle radio button). While I do need to enter the Gateway, I do NOT need to enter the IP. The panel will show the assigned IP once you've connected to Theoldnet Modem's PPP server using the MacPPP control panel.

    Great idea, thanks!

    Getting my SE/30 online

    I've just connected to the Macintosh Garden with an ancient browser from my Powerbook 180 using Theoldnet Modem. I'm using Zterm 1.0.1 (from the Garden) to talk to the modem. I'm using MacTCP 2.0.6 and MacPPP 2.1.1 (from the Garden). I'm using Netscape Navigator 2.01. TCP and PPP are set...

    PowerBook 1xx Case Screw Replacements

    I just measured one of the grey bottom screws from a Powerbook 145 I have here. It looks like 6 mm to me. See image. I think you're good with T8 6 mm. Good luck!

    PowerBook 1xx Case Screw Replacements

    All 4 screws that serve to connect the bottom case to the top case are the same. There is a fifth screw at the back of the machine, near the modem port, which is smaller - do you have that screw?

    PowerBook 1xx Case Screw Replacements

    Where in the case is your remaining screw located? I believe they're all the same (unlike on a Powerbook 180 which has a different screen, where the screws that hold the screen in place are shorter that on a PB 140/145/160; not sure about the PB 170 but I guess it's like the 180). The screws...

    Tunnel Vision On Monochrome Active Matrix Powerbooks

    I put a 180's screen with moderate tunnel vision in the oven at 98°C for 12 hours. The tunnel vision effect is much slower to appear now, but appear it does (after 30 minutes or so). My conclusion is that the liquid crystals themselves are degraded, and that short of cracking open the panel...

    PowerBook 165 screen issues after a recap

    Have you tried mounting the screen on a different chassis? I had a screen that appeared half broken (top half with stripes). After I‘d swapped the mother- and daugherboards (from another 160), the screen worked just fine.

    Tunnel Vision On Monochrome Active Matrix Powerbooks

    The result of this experiment is: The IR lamp does not sufficiently ameliorate the tunnel vision. I'm stopping now. Interestingly, the screen didn't get any worse either, although it's been exposed to a lot of heat. If the tunnel vision effect is really caused by moisture, that moisture...

    Tunnel Vision On Monochrome Active Matrix Powerbooks

    I've now let it run for 2 x 6 hours. I let the screen cool down and tried it. No change (tunnel vision is still creeping in after a few minutes). Maaaaaybe a bit slower than before. But it has the same extent. So I'll keep toasting the machine.

    Tunnel Vision On Monochrome Active Matrix Powerbooks

    I could try turning on the Powerbook as its screen is being toasted… what do you think?

    Tunnel Vision On Monochrome Active Matrix Powerbooks

    Not sure that the desiccator is hot enough to really get the water out. I‘ll continue toasting tomorrow.

    Tunnel Vision On Monochrome Active Matrix Powerbooks

    Strangely, the screen gets hotter than the bezel. The IR lamp is a 100 W lamp - it's not all that hot. I can still touch the screen (briefly).

    Tunnel Vision On Monochrome Active Matrix Powerbooks

    It's toasting now. I'm doing the left side first, this is where the worst tunneling is taking place.

    PowerBook 140, 145, 145B, 160, 165 LCD Displays

    145, 145B (both Rev C), 160, 165 screens are all the same. See this myoldmac list.

    CCFL backlight in PB 145 / 160 /165 = CCFL backlight in PB 180?

    Thanks! I plan to open the Bezel and disconnect the CCFL cable plug. I understand that there will be a couple hundred Volts (at very low amperage), so I plan to use a CCFL cable from a non-functioning powerbook, plug it in, and cut off the dead CCDL - in this way, I should be able to safely...

    Tunnel Vision On Monochrome Active Matrix Powerbooks

    OK I'll post my setup once the lamp arrives and is in action. That'll likely make you laugh even more :-D
