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...

I have two and both say apple on them. T he ey look like this one —> https://guide-images.cdn.ifixit.com/igi/WPuQpgkMjrYZvbDi.huge I read somewhere that they are express modems and then found the software and that solved the issue. A whole new control panel for it.

I finally got my PowerBook 180 built in apple modem to work by installing the express modem drivers from the custom install options on this cd image: https://macintoshgarden.org/apps/apple-telecom-v303

It’s the power management system for the battery. It is right next to a bunch of caps and gets corroded and dies. Both SuperSVGA and Androda have made and sell replacements. Here’s a pic of SuperSVGA’s :

ill send some photos. Yeah I have fixed several now... the worst ones for me so far are IICX boards so far.. this particular portable boars was is BAD shape.. the previous person who tried to re-cap it had no idea what they were doing and lifted a bunch of pads and traces as well as burned up a...

Interesting i haven't heard of that.. im just going through the board with a magnifier, scraping off corrosion, continuity checking and solder patching with micro thin wire I have had to drill out a few vias with a .3mm drill bit about the same size but not sure if these are multilayer boards or...

Nothing new form me yet. Something to do with the RAM... either a broken trace or a bad RAM chip itself but I am leaning towards a broken trace because at this point I have repaired about 4 or 5 boards and its always been traces, caps, and hybrid boards.

Exactly. I bet they’re about 2,000mah. That would be around the same as the original packs. I’ll test them and find out when I get my load tester. These are the batteries I used: Deleepow AA Rechargeable Batteries Nimh 3300mAh 1.2V Batteries AA Size Rechargeable High Capacity 1200 Cycles...

I just made a new pack yesterday. Ended up modeling one myself since I wasn’t able to edit the STL. I made two packs. One with 10 1,000mah NiCd AA batteries which gets around 1.5 hrs runtime and another with 10, 3,000 maH Nimh batteries that’s getting around 2.5 hrs runtime. I haven’t done load...

Ok thanks. I’m sure it’s a broken trace somewhere. I have found and fixed several already. Just hard to fin. The first error I got was a power manager handshake error so I replaced the hybrid with one of yours and then got the same error! So I Probably ruined a perfectly good hybrid. Turned out...
