A2000 questions
« on: May 27, 2004, 05:11:27 PM »
I just got an A2000 rev. 6.2. It's my first ever A2000. :-)

Anyway, the specs for now are bare-bones. 1MB chip ram, ECS chipset, no HD, 68k CPU, 3.1 rom.

Everything works great, but when I turn the system ON, for a second at boot the screen goes RED, which indicates a rom error, if I know my Amiga colour codes correctly. After the 1 sec red screen, I get the 3.1 kickstart screen, and at that point everything works fine, but that red screen makes me wonder... :-?

Any way to make it go away? :-) I've tried pressing down on all chips, and it didn't help. Perhaps I should start replacing them one by one? I've got a fully populated A500+ motherboard which could be of help.


Thanks in advance for any help/tips.

Yeah, that's the best place to start. I have a KS1.3 rom as well, so I can replace it with that 3.1 rom which is used right now, and see if the Amiga would still show the red screen afterwards. If that doesn't help, I guess replacing custom chips one by one will be necessary.

Yep. This is true for all PLCC sockets of similar size with Amigas, such as Buster, DMAC, Ramsey, etc. sockets. It seems that the plastic design of those simply weakens over the years due to age.

You definitely should only use a PLCC chip puller tool, and be very patient if the chip in question doesn't wanna get out nice and easy, because excessive force and wrong tools (like a screwdriver) will most likely crack some of the plastic, if not destroy it completely. This doesn't always apply, however if your plastic sockets are weak, they will get damaged.

I solved the problem. It seems that Denise was flakey. I replaced it with the one from my A500, and the A2000 boots fine now, with no problems like the red screen or similar.
