The connector appears to be called AMP/TE System 50 according to this catalog. Part number for the plug end for the 72-pin cable is 2-111196-3. Part number for the board end for the 60-pin cable is 1-5111595-2, 1-5111595-4 for the 72-pin version.

DaynaPORT wifi sounds like an incredible feature to be sure, but there's one issue - changing the SSID/password is going to be problematic if it requires opening up the computer to access the SD card. Every single time a Powerbook is taken apart it's a huge risk. Would it be possible to perform...

Any chance of any more of these getting made?

I have a theory that these modules can also cause a problem where if you mess with the contrast control enough (moving it back and forth repeatedly) the screen turns off (backlight stays on) and doesn't come back until the system is rebooted. I swapped in a module from a dead screen and it went...

I was able to do the exact repair you did on a LM64P51 using a dead LM64P58 as a guide (there appears to only be minor trace layout differences between the two). All of the horizontal TAB bridge thingies are connected to each other on each pin and I just reconnected the one that wasn't.

Any luck tracking down the connector on the interconnect PCB end? There's an early blue one that's worse than the AMP one and impossible to get off intact.

The problems with PowerBook LCDs are the same as all handheld console LCDs, just scaled up. Of course, with consoles you have a huge selection of perfectly engineered drop-in modern LCD replacements and with powerbooks you get to pay $300 + trumpriffs for an allegedly NOS panel on aliexpress...

If you're having problems getting the optical drive to read burns I have found that OS9 will install from a ZuluSCSI if you use the CD emulation feature (just drop the iso in it)

The freeware versions of 5.2 and 5.1 appear to be hosted here. Should probably mirror them as they weren't easy to find. The non-freeware 5.2 remains elusive.

It does make it much less likely that someone's messed with the configuration. If it was messed with and not reset, I probably would be getting a local console and not the default serial console. It does appear that there's no extra EEPROM or whatever storing the OpenFirmware settings and that...

OK that makes sense. I'm just wondering if something in there's been messed with as I can't get any of the 4 USB cards I have on hand to work no matter what drivers I install. The CPU also still shows as 133 mhz in System Profiler even though it should be 150. Are OpenFirmware settings saved in...

This is apparently one of the first systems to have it. Is it possible that it only works over TTY?

I get a black screen of nothing if I try. The system boots and runs normally (well, I am chasing another problem with getting USB cards working but I don't know if this is connected). I have mashed the CUDA button plenty of times, reset PRAM, PRAM battery is working. The machine apparently...

Nobody's sourced any I don't think, but they crumble so badly and so often that there's gotta be a bunch of whole analog boards for them floating around.
