PowerBook 180/180c daughtercard compatibility with motherboard
Posted by: croissantking on 2024-02-21 16:57:57
I have a PowerBook 180c daughtercard that I want to use with a motherboard that came with a 180. I see that the m/bd has the same p/n so I assumed this would be fine. But on closer inspection, I see this:

Compare to 180c version found on the web:

Has anyone tried interchanging these?

Hmm... I wonder where that came from? πŸ€” 😁

FWIW, here's a shot of the motherboard from that 180c :

Not sure what to conclude tho.

I see you have the glue dots that indicate it’s for a 165c/180c:

The difference has to be marginal - maybe some option resistors set at the factory?

I have a spare 180c board if needed

This may not be relevant, but I have swapped the CPU cards on my 170/145B/140 all around and they have all worked with each others CPU cards and RAM. I have been running the 145B with a 170 CPU card for almost a year at this point without issue. I don't remember anything like that indicating a difference in boards however...

The 140/145/145B/170 all use the same motherboard so that's why that works. I don't know as much about the color vs. grayscale 2nd gen models, but if Apple called out that they were different, I'd expect them to actually be.

I plucked up the courage to try and it works just fine.
