A3000 Problems
« on: October 08, 2003, 07:21:39 PM »
Hi there,

I'm trying to revive an old 3000D/25 I had lying around. It seems to have issues, unfortunently.

The first one, and obviously the most annoying is that it's guru proned, most often while booting up a disk or starting wb from hd. When it's up and running it generally runs pretty fine. It often starts this way, ie. when I press power on it immediatly goes into the "Software Failure" mode. A couple of cold/warm reboots usually gets it going.

Another thing, dunno if it's related though, is screen garbage. Horizontal lines, much like when you overclock a gfxcard too high.


I've tried reseating most chips, daughterboard, taking out all zorro cards, etc... I also bought a pair of 3.1 roms for it since I thought that might be the problem, but no change.

A wierd sidenote that might be related, I cannot run the chips at 25 mhz... Yellow screens, not working well at all, etc... With J151 at 1-2 and J152 at 2-3 it runs, but only as well as described above.

Thanx for busting up the thread guys =). I already have a 2500UX, aswell as a 500, 1000, 1200 and 2000 so getting ANY machine to work wasn't the issue, just the 3000.

However, I got hold of a "A3000 burn-in disk" that reported something was fishy with my fastmem. Removing it solved the major moodswings, but it's still got some PMS issues. Very often when i cold-boot the machine it goes directly into "Software failure"... and I still can't run the machine at full chipspeed.

The battery looks whole, the PSU... dunno, guess I could measure it. Does anyone know if the 3000 get's that "sync" signal from the PSU as the 2000 does? If not it might be easier to install a PC PSU.
