Ask @Melkhior

I wonder if it says anything under the label. It’s hideous!

The 475 wouldn’t have come with anything as small as a 40 - I think they were specified with 80, 160 or 250mb drives. It’s normal to have a speed differential between different brands/models of drives - the faster 40meg unit might be a newer design with a single platter vs multiple platters...

Sometimes LCPDS ethernet cards come with the machines and you end up paying the same as a standalone card. My vote goes to the 475 - soft overclock and an easily replaceable PSU are big advantages.

Has anyone designed a pcb for this?

Not sure about that, I’ve spent literally years trying to fix ongoing issues with PowerBook 160/180 boards, without a great deal of success.

The write up is definitely AI.

LLM alert :poop:

Not really. I’m grasping at straws…

Nice diary, very thorough - definitely helps with diagnosis. At this point I would try using the PB with a different drive entirely, taking the PowerMonster out of the equation. Do the problems go away? Edit: Ah, you say that you disconnected the hard drive ribbon cable entirely and the issues...

Thanks for taking seriously my slightly facetious comment :p I agree about hardware limitation but just for the sake of covering all the bases, can I ask which version of Mac OS are you running, and therefore which version of the Apple CD-ROM extension is enabled? Were these early Macs using...

I see a group of about 7 or 8 pins that are slightly bent, can you very carefully straighten these? Looking again, there are a few others on this side of the chip that are bent, inspect carefully with a magnifying glass.

Most likely a faulty RAM card (one or more chips dead). You might try blowing some contact cleaner in the connectors just to rule out a bad connection. It’s a 16MB card.

If the Mac is turned upside down, the CD will be the right way up... Et voila.

Here’s a pic of the PB160/180 board
