Calling all Duo owners! (especially those with a 270c!)

[3lectr1cPPC]

I'm working on getting cap reference values for various PowerBook Duo laptops for my website. The 270c is an 030 Duo so I assumed that it would have the same logic board as the 210/230/250 but I've seen conflicting info elsewhere, mainly, an older thread with some incomplete photos that shows the same capacitor layout as the Duo 280, 280c, and 2300c logic boards. I know it's possible that that 270c got a logic board upgrade at some point, so I'm asking the community: Can anyone with a 270c snap a photo of their logic board so I can set things straight?

Thanks!

And if anyone would like to help further, here's the values I have and which I'm missing:

Model	Currently Have	Mssing
Duo 210	Logic Board, LCD	Inverter (if it has any elec. caps)
Duo 230	Logic Board, LCD	Inverter (if it has any elec. caps)
Duo 250	Logic Board	Inverter (if it has any elec. caps)
Duo 270c	None	Logic Board, LCD, Inverter (if it has any elec. caps)
Duo 280	Logic Board	Inverter (if it has any elec. caps)
Duo 280c	Logic Board, LCD, Inverter	None
Duo 2300c	Logic Board	LCD, Inverter (if it has any elec. caps)

I can use any of the following values, and especially images of any of the following parts to use as reference photos on my website. The only Duo images I currently have are Logic Board photos for the 210/230/250 and the 280/280c.

I would love a cap BOM for the 2300 logic board; I have a machine on my "to do" pile.

I’ve got the caps list on my website for the 2300c LB! Don’t have mouser P/Ns but you can probably figure that out in your own.

Will do - thanks!

I thought I'd already replied to this? 270c board has a color connector in a different location than the Grayscale connector in earlier Duos. The 2300c is the PPC upgrade for ALL Duos that Apple promised. Duo 2300c has connectors for both types of screens as well as the IDE upgrade connector while retaining the old SCSI connection in the same location as the previous models to support their HDDs/Cabbles.

I'd love to have a Mouser parts list for the 2300c if someone puts one together.

Think you posted this over on the TinkerDifferent thread. Easy to get confused when there are two forums… ah well. If you’ve got the values it isn’t too difficult to find the parts on your own. The only sticking point is diameter and other dimensions. For the duo you’ll want to find the smallest caps possible anyway though because of how tight the spacing is.

I completely forgot to get the 280 inverter board values for you! I get a duo 230 tomorrow or the day after so I will pull both apart and get the values then. I can also get you some photos of them including the 230 display if you need as well.

Thanks! All that is great.

Just got a chance and neither the 280 nor 230 has any inverter board electrolytic caps.

Good to know. Thanks!
