I like this a lot. One of the reasons I think many (myself included) would be hesitant to contribute to the wiki is that it has been so frequently offline for long stretches of time. This combats that somewhat, although I think the most important thing y'all can really do is make sure that it...

I have no problem with people reproducing the capacitor reference data on the wiki. I will note however that if you also wanted to include images, the vast majority of reference photos in MacDat's cap reference library were sent to me by other people. You would have to reach out to them to ask...

I see a few things that should be changed. - Note the 25V distinction with Tantalums as mentioned - Hardly anyone uses the described method for removing the original capacitors. No one can agree on what the best method for doing this is (twisting them off, hot air, clipping them off, soldering...

already grabbed it, will be up soon

Can confirm. I had my 150 out a few days ago to test my spare floppy drive (someone on the forum is looking for one) and the trackball has stopped working. I don't actually think it's the trackball, but something else in the chain, because swapping out the trackball and the keyboard didn't get...

That'll do it.

Interesting. If it was used in any other laptops, then I haven't seen one yet while making my database which currently has specs for 2500 models. Probably because a basic framebuffer chip that only supported grayscale displays was rather primitive by 1992 PC laptop standards? I wouldn't be...

Based on the fact that I've never seen it appear in a PC laptop, I'm inclined to think it's custom. C&T's normal lineup followed the name scheme of 655xx (65520, 65525, 65530, 65535, 65540, 65545, 65546, 65548, etc)

I'll try to get you photos sometime in the next week. Please nag me about it if it's been longer than a week and I forget.

If "Rev A" is the Sharp LM64P51, then I can confirm it works perfectly fine in 16-grayscale mode when hooked up to a PB160. I don't know what the technical difference between the P51 and P58 is (that's something I would be curious to know). The boards at a glance look pretty identical. Maybe...

Thank you for clarifying this - since I made my original post a few years ago, I have seen several examples of these screens developing vinegar syndrome, so I was definitely wrong in my earlier statement. It does seem to be less common as compared to other display types, but it absolutely can...

So they used a through hole capacitor which has the surface mount style can? Weird, I’ve never seen that in equipment from this age. I’ll add the reference info to MacDat, thank you for letting me know.

Gameboy film is designed for passive matrix LCDs, so it won’t work here. I don’t know if these monochrome panels use anything special or not, but I’d try standard TFT film first.

ditto to herd - you’ll need to get a CP2112 or similar device to communicate to the battery over SMBus. Not a difficult process once you have the hardware, and it isn’t expensive. If you need the software required to talk with the battery then you can DM me.

Oh good lord, this is some of the most brittle plastic I’ve seen. My other three 500 series batteries were all a fight to get open. The plastics were still very pliable. This thing? Totally different story. This is the only of the three with these purple cells inside - it’s labeled EMM-P so I’m...
