After the 1st cleaning run its better: DSC_7247.JPG There is liquid below the 1st PCB layer but I think I will leave it as is at the moment. When removing it will not look good anymore. I also expect the 74F27PC needs to be replaced …

There are also rechargable coin cells available. I have never tried them, but they have been recommended here several times.

Does the BIOS keep the data you enter in the CMOS Setup? Did the old battery cause damage when it leaked? Is there a jumper for internal/external battery?

Hi brostenen, I am currently also caring about my 3 new Amiga. Completely disassembled and cleaned them. I never owned one and I am surprised how repair-friendly they are. The 1st one looks like new now :cool: Mainboards seem to be OK except the one in the A500+. The battery started leaking and all …

Main reason to get it that I was afraid the seller is going to scrap it when nobody buys it. Was not that interested anymore. He told me that he …
