Har vad jag vet bara fungerande Portable
imgen extra nät del
Hittade min PB 100
Men den ville inte starta
Tack för uppdateringen. Har du 45W nät del för ibook G3, 1400 eller mikrofon, skärm låsa detektor för Duo. För vilka Duo har du skärmar för?
Vad skulle det kosta att ha det PB100, Duo delar och 45W del (om det finns) inkl. skickning till Helsingfors, Finland?
Hej har till iBook G3
Tror det fanns både YoYo laddaren o den fyrkantiga vita / Avlånga Svarta
Kommer inte ihåg vilken AcAdapter 1400 har men har troligen
Har sett 250:- som pris
Microfoner har jag både den gammla runda (Grå) o PlainTalk (Grå o Genomskinlig)
Beg eller i Kartong
lite rörigt i förrådet
Men just nu har jag:
PB Duo 210 Komplett o fungerande
PB Duo 230 Saknas någon del Men okey

(Men Iallafall skärmen är kanske såld)
PB Duo 280 Troligen Gråskala
Fungerade Men sist ville den inte startade
”Skärm låsa detektor för Duo”
Har du en bild på den från kanske ItFixIt
PB100 är komplett Men vill inte starta
Om jag inte fått något bud, som jag har tyckt vara bra
Har jag satt ut det på Tradera
T ex om du tycker AcAdaptern är värd 125:-
Så har jag satt ut den till det priset på Tradera, om den intresserade har lovat att bjuda
Då har Tradera fått avgöra vad den är värd
Nu har jag tagit en paus på Tradera på 1-3 veckor
Fortsätt gärna på E-Mail
Frakt Troligen billigast

Hittade bara för 5Kg 280skr o 10Kg 390skr

If I only had one Anyways I found the problem (I had accidental dropped solder on a memory chip, it is visible on the logic board picture above) and the computer now boots to a flashing disk screen. The HD is marked as bad, and it didn't do much than whining when attempted to start it up. Regarding the PSU there is a long thread from 2011 to 2013 discussing about it. I know the thread is old and more knowledge has been gathered, should one use 2/3A PSU or no?
Hmm, did some trials and it seems that the computer starts up (almost) every time if I plug in the battery first. It doesn’t boot up with charger only (I guess this is expected) and I need to RESET + NMI it to get it to boot if I plug in the battery after the charger. So... most probably it works from power mgmt perspective and the sad Mac is because of a bad trace etc.
Hi, I would appreciate some guidance... I recapped "recently" (like year ago or so) acquired M5120 and plugged it in for the first time. I got a chime and a sad mac. While trying to make it easy to access the board while powering it, it did a smoke on pin 10 on J22 (yes, it is a ground pin but the Portable case is conductive, so it touched something else where). Anyways, searched through the forum found out that pin 3 on Q4 should give you ~5.2V. I get 5.15V sometimes (usually after a small break without a charger and with a charger from PB 165c, 3A) and I can get it to chime again. Most of the times I get 0 (on battery) or 1.3 (if charger is plugged in). The charger gives 7.6V whenever I've measured it and possibly even charges the battery (or at least I've seen it increase from 6.3V to 6.36V but it might also be the battery recovering). I have used IPA and a brush to clean board where necessary. I've never cleaned my boards by washing so if that would be the next course of action, how do you wash them? With plain water and a brush and do you use regular household oven to dry it? Also suggested on the forum is to use flux and heat station on Hybrid, I don't currently have access to a heat station so can't really try it out. Pin 3 on Q16 and Q20 gives either 7.6V if on a charger or 6.3xV if on a battery. I guess that is correct. Pin 1 on Q16 is around 3V. Pressing RESET + NMI does not change anything on the 5V (so it stays the same it was prior pressing them, be it 0, 1.3 or 5.15). Thanks, Harri
Please find attached some more pictures. The power supply is with AT connector and has been attached to the Lisa monitor power in. Then Lisa’s video / logic board connector is sliced and a regular Mac compact connector has been connected to it. I know nothing about Lisa connectors so my assumptions might be totally wrong. That scsi cable is interesting. There is no scsi in 512K so it might be this has been used as test bed for fixing compact logic boards. Does someone know what is that stick with three wires?
I will. There are 4 other compact macs and various analog and logic boards so I’ll try to sort them out first. That stacked memory logic board just stroke as was it couldn’t fit a compact case so asked the guy how he had been running it.
Sorry to revive this 5 years later but I obtained a similar 128K board with a stack of ram. The lot also included empty Lisa case with non-standard PSU in which the board had been. The seller had modified the board and Lisa by himself (afaik) and he used to work at it department of a local university. I haven’t tried it out but if there are some questions you’d like to ask, I can reach out to him.
Finally, I can report a success (I hate when people don't finish a topic they started, if it got resolved or not). Sound and ? floppy. The sound problems I was able to find a potential cause from here: And it was indeed a broken data line to ASC (among many others ). Funny that the trace looks fine (no black rot) but doesn't work between the UJ11 and the first test point. I even removed the (previously replaced) caps C9 & C10 to check the trace underneath. For me, the most surprising thing was, that once audio started to work, the ? floppy appeared as well.
Thank you @Bolle, I found UC8 pin 13 not connected. After fixing the A(11) connection the picture looks good (I guess I could have taken A(11) closer to UC8 ). The programmers button still produces same error code (0000000F,00000013), I've lost whatever sound I had (some beeping), and no ? floppy. Further guidance is appreciated.
Spent couple of hours cleaning the board even more, adding jump wire for C6, found that trace between circled leg and and its other end is broken, jumped it. Anyways, no change in out come except some attempts to play something from audio but it also fainted away after few resets. I also realised I get sad Mac if I press the programmers button.
