Fair enough, bibilit
I have a 2MB board in my PB100 that has printed on the PCB “For PowerBook 100/140/145/160”, and in my other PB100, I am using another 2MB RAM board (two chips each side) that was originally from a 170 I thought, but I respect that not all boards will be compatible with all models. Mine are both 2MB, I imagine the larger boards are likely not to fit.
There is also the possibility of boards not following Apple’s guidance to ensure 16/32bit compatibility (PB100 having 16-bit RAM and the others 32-bit). I think boards originally fitted in standard configs would be compliant, but how many are standard by now, I wonder.
Thanks for the link, it is tempting to spend $79 on that 6MB expansion to get 8MB total, but I really shouldn’t
I was thinking of downgrading to 6.0.8 instead…
