RIP: A3000 #-(

[vk3heg]

Was happly playing around with my A3000, compiling a new Linux kernel for the beast! (It's towerd) After
getting a brand new X-Surf network card a few weeks ago... Leave her alone, and turned off for a few days.

Come back to the system, and she's dead jim! (Star Trek pun intended).

Strip the hole system down to just the motherboard and riser card (So out comes the X-Surf, Cybervision 64,    
A2091 [Has my cdrom on it], Cyberstorm MK1 68060, 128mb ram).. Run some test's, get the nice kickstart boot    
screen with insert floppy.. Coool, things might workout to just be a dead Accelerator card..

Couple of days latter (when I had the time to spare), run more test's.. Boot up with just a workbench disk,    
and nothing else hooked to the beast... A few minutes latter and the &^%^%$& thing has locked up frozen (cant  
do squat).

Wish there was someone closer with another A3000 or A4000 to test things in (the closest I know of is MAUG    
[Melbourne Amiga Users Group] 120K's away.


So I might get a working system one day... Have been sending email's back and forward to Jean in france... So  
half my gear is going to have to take a world trip just to get board level work done on it...  

Then if i'm lucky it's fixable...

Now that definitely does NOT sound good   :-(

Have you inspected the main board to see if any chips have become dislodged out of their sockets?

It has been known that a gentle push on all the chips to ensure they are seated properly can hep where other methods have failed in the past.

Give that a try before setting your phaser on kill and taking careful aim  :-)

Yep, done that.. *IF* I get a chance, over the weekend it'll be pull the mb out and inspect/use some force...

Turn it on with no keyboard / mouse /anything CIA related and see what happens. Difficult to notice freezing that way so you might need to boot with a game or demo-floppy.

Power supply?

Forget the force Obi-Wan ... Use a hammer, it's our only hope!  :-D

@vk3heg
Just read your Pmessage.

I was going to suggest trying another CPU board in your A3000, or try the onboard 68030 to isolate the fault to the motherboard or CPU board.

Sounds like you've done this already??  Faulty Cyberstorm mk1.

Otherwise it might be worth reading through my A3000 non-booting notes here to see if there's anything else which might give you some clues.

I can do component level repair for all Amiga motherboards, and limited repairs to the Cyberstorm.  Limited because there is no service information available, and obtaining replacement programmable logic, of which the contents is 'secret', is not possible.

Feel free to send me an Email if you'd like to discuss further.

LOL

@vk3heg

My 3000 appears to die about every 2 years.  I clean all the dust and reseat everything a few times and it comes back.  There are chips on the MB in the corner under the Power and HD LEDs that run hot.  I have an extra fan blowing on them.

If you run out of patience or give up, don't pitch it in the land-fill.  Sell it for parts, there are too few left.

The Hospital visit:

Took my system on a little trip today (160Km round trip) to get tested etc...

The A3000 is alive and kicking...

The cyberstorm mk1 '060 board is dead though. The cpu tests ok in another accel card. My accel and other cpu dont work.


So anyone got either a '040 or '060 accel card for the A3000/4000 that takes at least 128mb ram, they wish to part with?
