Hello,
Recently, I found an old MS-DOS laptop from the 80s, which to make a long story short, took ALOT of work to restore back to working condition, finally, when I was done, the charger, decided to just die, simple as that, it... just... died... it has an LED indicator, which no longer lights up, worst part is the jack port is unique to the laptop, it's proprietary, and it has 8 pins just for power, no data, just power, luckily I was smart enough to map what each pin puts out as soon as I noticed it was proprietary
Here is the best schematic I could make out of the jack:
As can be seen, it seems that there are a few different power rails here, which is kind of weird for a laptop power jack, so how do I even rewire this to another power supply with only two power rails? (+ and -) do I stick the positive wires to a single positive rail on the newer charger, and negative rails to the negative single rail of the new charger? is that a good idea?
Also if you notice the schematic, Pin6 seems to have no connection, perhaps it was meant to be connected to the yellow wire but lost connection due to flex based damage?
Advice is very much appreciated, thank you
