GVP 3001 Fried?

[Aldren]

I suspect that either my GVP 3001 (IDE, 8MB RAM, 50Mhz '030) is fried, my SCSI card is toast, or the A2000 motherboard is starting to go.  Here is my logic:

It used to be (way back when I first got it, about a month ago) that it worked fine.  And this was good.

Then, the SCSI drive (DH1:) sometimes wouldn't show up at all.  And this was not good.  A few reboots or power cycles, and it would come up and function just fine.  And this was good.

Then, yesterday, it started giving me Software Errors (8000 0004).  These would happen randomly, up until the point where it was happening on every boot, or it was constantly rebooting.

Then, I decided to open it up and start pulling cards.  First came the SCSI HD.  No dice.  Then came the GVP 3001.  Suddenly, it started working!

I put the SCSI card back in and booted from an old WB1.2 floppy, and the SCSI HD showed up.  That was good.

Then I tried putting the GVP 3001 back in, and was greeted with a red boot screen, every time I started up.  Sometimes, when it booted, it was yellow, but most of the time it was red.  Pulling the accelerator allowed it to boot again.

Has anyone else experienced this problem?  Can I just replace the CPU on the card?  Or do I get to sell my 8-1MB 64-pin GVP SIMMS, because they're now useless to me?

Howdy, the GVP 3001 '030at50Mhz I have has no IDE.  It has internal & external SCSI connectors.  So I wonder why you need another SCSI card.  From the different faults you have listed,  and that it works without the Combo card, I might check the power supply.  Whenever we would get non-consistent faults from a box, it would frequently turn out to be the P.S. as the "ripple" voltage was high enough to toggle bits.

Just a thought,

Hang on to those simms... I may be able to help you.  I've got a GVP Combo board (030 at 40MHz) (the upgrade to the 3001 sandwich).  Since it is part of the stock I picked up in Texas, I'm willing to let you have it cheap.  If you can figure out the problem with the system all the better.  I don't have any software or manuals, but those simms would definately work on it (comes with 4MB already).

In all honesty, I'm not sure where to start to fix the problem, but the yellow boot screen means there is a logic problem in the 68K/accel slot.  Yes I know the link is for 1200 & 4000 models but parts still hold true for the pre-AGA systems.

:pint:

Thanks.  I saw the page you linked to regarding the startup colors, I just didn't know they were accurate for the 2000.

In case it IS a power problem, I'm going to remove the Kitchen Sync and Genlock boards that are in the ISA slots, in the hopes that having fewer power-drainers will smooth out the power.  I'll post back with results.

Joy of joys!  It turned out to be much simpler than all of that.

This Amiga, which I recently inhereted, seems to have gone through some abuse in the past.  Upon closer inspection, the CF slot had two pins that were less-than-optimally aligned.  Consequently, when I started up, they weren't always making contact.

It was actually kind of interesting, in a torterous sort of way: if I started up and pressed slightly left on the card, I got a red screen, and if I pressed slightly right, I got a yellow screen.

Took a screwdriver and bent 'em back in to place, and my card is working again!
