Re: A500+ Help me Obi Wan, you're my only hope.

For the blink codes look at: http://www.lemonamiga.com/forum/viewtopic.php?t=13978 The first thing i would do is use http://www.amigapcb.org/ to check the traces for breaks and shorts, also check under IC's when in doubt. If you have the correct PLCC puller i would also reseat Agnus after cleaning t...

Re: PJ-V2's 530 Build

IMHO, Personally i would never use two power supply's (USB and bench), that is asking for trouble, especially if you didn't connect the GND wire before the 5v with the USB already connected. Does one of the CLPD's get especially hot? If the RPi reads a nice 5v (this depends on the used PC/cables) I ...

how many times does the power led blink?
Disregard that, was thinking of another machine :-)

Did you swap the Cia's?, there is a OVL line that can cause green screen problems..

Re: Advice on fixing an Amiga 500+

Well, Green is a problem with Chipram normally, how many times does the power led blink? Did you replace the kickstart with exactly the same chip? Personally i would check: 1. The pcb again with the help of http://www.amigapcb.org/ 2. Using Diagrom 3. The Agnus socket Piggybacking ram will only work...

Re: Kai's TF534 Build

If the solder is dull it can also be a sign that it has been heated to much, and as stated before it could just be the quality of the solder.
