Title: A608 problem
Post by: orange on December 01, 2017, 09:34:59 PM

I have a problem with the A608 RAM expansion for Amiga 600. It used to work, but after some fiddling with leaked caps, and other stuff, it causes A600 to constantly reboot.
what could it be?

What could it be?  Is this a quiz?  I'm going to go with either "some fiddling with leaked caps" or "other stuff". :lol:

I know it looks very bad, but it did work; don't want to recycle it. Now I get yellow screen. I'm almost sure the problem is in the CPU socket.

I've managed to repair it with a help of friend :)
If someone has similar problem, best way to find broken trace/line is to attach the expansion to motherboard, then check traces between extra DRAM chips and ROM, for eg.
now its secured with hotglue.
