Pretty sure they are the same if you have a REV 1 classic analog Board, rev 2 analog board have a square looking unit.

Both of my Color Classics have 575 Boards, but I offer you a community sourced schematic: https://drive.google.com/file/d/1gB029UsD3JoRYssmSmX2rUhhPEoVPhed/view?usp=sharing

Not bad, especially for Mac II or SE with a spare internal floppy port.

Cool!

If you have one more I got a portable that might need it, it was turning on after a recap and now is not for whatever reason.

:( Really?

HI all, Not a programmer, I'm curious if anyone has any experience with Think C, I'm trying to see if it's possible to de-compile the original Transport Tycoon and translate the Japanese to english: https://www.macintoshrepository.org/27024-transport-tycoon-jp- I've enjoyed this game on dos...

No, When I say 4000 mah, it's two 3.7v batteries in series for running but split up for charging. One 5v regulator but two charging ICs.

Actually I have a design that can be used on the black and white models. I'm just very busy right now and can't mass produce them, but I'll sell you my one and only prototype. I can also release the files at some point, but I'm very busy right now so I will not be producing more at this very...

Classic boards are the only ones I've been able to save after a battery leak. It's best to clean the corrosion, remove parts in the area and check traces.

Maybe someone could adapt a Pistorm: https://amigastore.eu/853-pistorm.html

If one just wanted to control plugs via the power key(without any software) on an ADB keyboard the process would be fairly simple. Because the ADB keyboard grounds the power pin whenever the button is pressed you could just use a set of relays in a holding circuit like this (but with ground and...

Yeah I guess, Basically you can't fully charge your batteries together with a 7.5v charger, you need at least 9 volts to charge a 2-cell lithium battery. In charge mode, my circuit splits the batteries so the can be charged individually, but doing this has the downside of the batteries not being...

Yes, it is. In fact I'm working on a pb140-180c battery pack using the same circuit.

Yeah, could be a faulty swim or cap goo in that area?

I've done the exact same thing and have not had a problem, is it possible you swapped a pin or something?

I told home that basically one will have to be disassembled, then I can make a schematic and then a pcb.

Yeah probably, nothing is stopping you from buying the parts and building this circuit.

Circuit may work but the form factor is not the same.

The board needs a wash and new caps.
