Somehow one of those cheap little FC1307 adapters and a 128GB SD card are at least behaving better. I'm getting almost the same performance and the second IDE channel isn't getting blocked. We'll have to see about reliability though.

The Ableconn does not work properly on the Wallstreet. It will boot and format and everything, but it somehow blocks off all IDE-based ultrabay drives from working - CD, removable, doesn't matter. Floppies will work because they're on the IWM bus. The ID jumper block is covered by the connector...

Oh and before you get the thought of hacking in the interposer board from one of the comparatively far more numerous ZIP and LS-120 drives for Wallstreet systems, the optical JAE-IDE pinout and the removable hard drive JAE-IDE pinout are completely different. Still, this could be the start of a...

Apparently a company called MCE made some third-party drives but they're so rare they might as well not exist. They almost certainly would have been standard JAE-IDE drives in a compatible frame. 1400 and 3400 drives are also a no-go. I have a hunch that a Japanese company might have made one...

I'm in this same boat. My CD drive just died. The drives are not anything normal or even abnormal that I've seen on other laptops even of the era so far. The Lombard/Pismo modules just use ordinary JAE connectors, these use a proprietary form factor where the module connector is connected...

I forgot: the source was released.

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.
