No. It’s a nightmare working on these. I went through 3 lcd panels and the third is perfect (as is) other than a dead pixel so I’m just crossing my fingers it stays that way.

Interesting ok I’ll try this when I dive back into it. I had to set it aside for a bit.

Ok that’s promising. I’ve got one IIcx that had such bad battery corrosion that there were green mountains all over and when I cleaned the corrosion off the chips were literally falling off the board. That whole corner where the soft power stuff is is gone. Most people would probably say the...

Great idea. I didn’t know they existed! Thnx. I have EagleCad that I use for my own boards. That should work right?

I haven’t finished yet. This board is 90% there though. It boots and then ram errors. It was completely THRASHED when I got it. I got it cheap on eBay. I think the seller tried to do a re-capping and threw in the towel. Lifted pads all over the place. All the connectors were melted so I replaced...

This particular one right now is a portable. But also got some iicx’s. Here’s the exact ones

Anyone know know if the vias on these old boards connect to traces in the middle layers? I ask because I’ve got some badly corroded vias and traces forcing me to have to drill them out and run a wire through the board.

Yeah I bought a whole other on 180 and between the two have made a pretty mint machine. I’ve put a BlueSCSI in it and too. Two ram cards and transplanted ram from one to the other and maxxed out the ram and then I built a new battery pack for it. Now with the Wi-Fi BlueSCSI it gets online too so...

Ahh, like EPROMS too... older they are and the higher the voltage they need, the higher the price...

and almost break even after adding my labor into the mix! 😂 I actually got a pretty good deal on the 8mb. I haggled him down to $30. Another guy in France I think is making custom cards and they are really nice but $120 or so for a 10mb… a little pricey. But then the 512k chips themselves are...

Bummer. Mine worked out almost perfectly UNTIL I kept tinkering with it and eventually ruined the upper 20 horizontal rows by breaking traces on the board. The baking completely fixed the tunneling but I had a couple lines at the very top that were missing so I kept mucking around with it and...

Well I had some in order from eBay but the card got here first so I just lifted those off the 4mb card as well along with the RAM chips. They’re a little larger than the ones on the Kingston board but they just barely made it.

Every thing worked out perfectly. I pulled 4 ram chips off my 4mb expansion card and transplanted then to the 8mb card and made it into a 10mb and it’s working flawlessly so now my PB180 is maxxed out :)

Haha yeah of course.. Ill make sure they are the same 512k's Assuming now before I crack the thing open I mean... Its a PB180 with 8MB is all I know at them moment...

I didn't know he had one also. I only know of Androda and SuperSVGA’s... The last board repair I did was giving me power manager errors so i pulled the hybrid out and replaced with SuperSVGA’s and still had the same problem and it turned out to be a bad trace by the power manager chip so I think...

OK I think I have a 4MB card in a scrap PB so i was assuming I could pull the RAMS on that and put onto this card.

Anyone know if I could simply add RAM chips to the vacant sections on this 8mb RAM expansion board to make it into a 10mb? Are those 1uf decoupling/ filter caps? would I need to add those as well?

Thanks I will go through the board and see what I can find.

Yes it’s the same issue as with the portable. I solved it on my portable by jumping power from the floppy drive over to the BlueSCSI so it boots up immediately upon wake before the system tries to “spin up” the drive. I’m not sure where to tap power on the PowerBook 180 would be though but...
