My 4k is dead.
« on: September 12, 2003, 12:15:54 AM »
Well after 10???++++ Hours of fault finding and soldering etc,  I think i wore out my probe, I am at the sad state of declaring my 4000 MB dead.
I replaced numerous components from savlaged parts and the thing won't come back.
If anyone knows where I can get another 4000 Motherboard that's got a socket for my Buster chip in Australia, great. Otherwise I just keep my eye on the trading post paper.

Sad days indeed. :-x

Says who? I'm sure i found the remains of a depleted uranium shell inside the case. I thought the hole was for ventilation though? perhaps not :))

Hmm.. Make me an offer, you'd have to pay shipping from the US though.

-Edit- It will be a couple days before it is available. I just ordered a bunch of barrel batteries. I need to change this battery before I sell this thing.

Do you have any ideas on what you may be looking for or expecting??  Does anyone keep such old H/W working condition?

I had one for a short while. It had a hand full of cards. Damn those desktop cases are cramped. It, also, had a major overheating problem. Which was solved by adding a 80 cfm fan unit into the 5.25 drive bay.

As too, keeping old hardware running. Hmm, Pray.

Well SHADES, I know of a guy in Tasmania who has a boat load of Amiga stuff, I'm sure he will have what you are after, he's a bit pricy though, can mail his email to you if you want.

Thanks mate,
 I'm not going to spend a fortune on antiquated h/w. OS4 is just around the corner and I want an AMIGAOne. The 4k I have is just very well loved.

What's actually the fault with it?

I have managed to repair a few A4000 motherboards - even one with the notorious "ECS only" fault. You could always take it to a user group meeting here in Melbourne and I could give it a quick inspection. There's a meeting this coming Thursday evening and another one this coming Sunday afternoon. If you are interested I'll give you the location details.

Please. That would be great. I have done a lot of work on it, replaced all the SIMM sockets etc, It just won't boot. It gives grey screen only. won't initalize the disk drives even.  I can change the scan frequency from NTSC to PAL no problems so some of it is working. However removing the A3640 get's the boot sequence to the same point, so it could also be the 040 or daughter card, or even the buffer chips in between, but so far, this is as far as I get.  I checked output on Alice pins and it's resetting, but won't reset again once you send a ground to the zorro reset pin.

You're welcome to have a look, I have converted the MB to a PC tower case with PC supply also converted however, I have it all removed at the moment to work on.

I no longer have any contacts to repair people, last guy who helped me fix it was Rob from AMi Tech and they are no longer around either. Such a shame, he knew what he was doing too. If you know the lazy bloke, tell him to call me!.

:)) he was always very busy :))

@SHADES

Well you have an A4000 motherboard and A3640 on the way which is in perfect working condition! Like I mentioned it has all the newest chips except the 3.0 ROM. Put in your 3.1 ROMs and you are set!

Let me know when the box shows up. I shipped it Global Express so it should only take 3-5 days.:-)
