AmigaOne-Xe/G4 board needed
« on: January 14, 2014, 02:45:37 AM »
I have a customer that has one AmigaOne-Xe/G4 board.
It is dead and I need a replacement.
If there is a newer board that the operating system from the AmigaOne-Xe/G4 will work on, that would be great too.

If that isn't possible, I guess I still need a replacement.

Thanks

Will

Their copy of Amiga OS will only run on AmigaONE hardware that was sold by Eyetech or their dealers and will not work on newer hardware such as Sam440 or Sam460 from Acube.

What testing has been done on the customers system.  Test the voltage or change the coin cell battery on the board.  If the charge drops below a certain level the system will appear to be dead.  Try that first.

The machine also has the ability to send self test data over serial to a terminal program via a null modem cable.  Just ask if you need more info.

As Rob mentioned, just replacing the cheap 2032 coin battery can make an apparently dead A1XE board appear to work again.

In case you are still in need, I have an AmigaOne XE motherboard that I was considering selling, but it has the G3 CPU module installed instead of the G4.

Out of curiosity, could you tell us any more about your company?  Do you routinely do Amiga hardware diagnostics/repairs?  Where are you located?  I'm sure others in the forum would be interested to know these things, as well.  Thanks, and welcome!  :D

Beautiful, the CR2032 did the trick.  Thanks.

Well, we started with Amiga, C64, PC, Atari, Mac.

But I am afraid over the years everything but the PC became unviable.  Amiga outlasted everything but the PC for us.  We used to do the agnus upgrades, 3.1 upgrades, hard drives, accelerators, had a full wall of software for the Amiga, loved the CD32 too.  But when it got down to 1 game sale a month, we just couldn't afford it any more.

Now we are a PC/PC Repair shop, but we still do service for the 1 Amiga customer we still have.

I still get funny looks from the guys when they do something nifty on the PC and I reply that the Amiga did that 20 years ago...  I miss the Amiga almost as much as Firefly.

Thanks again for the help guys.

Nope, Bothell Washington.

Hey, as long as you love what you're doing ;)

You know, if you wanted to get back into the Amiga repair business I think there could be a market for it. I'm not sure there's anyone else doing repairs in North America now. It'd be a different sort of work than what you might remember - lots more soldering and board-level work these days. Just a thought... :)

Here is a really cool feature of the AmigaOne XE/G4 and it helped me troubleshoot and fix mine.  This takes all the guessing out of why it is not booting.  I hear other AmigaOnes have this feature as well, however, I can't say for sure.

Connect a null modem cable to COM 1 (left port) and then use a terminal program.  I used Teraterm it is free on the net.   I also used a USB to 9 pin serial dongle.  Set the serial to 115200, 8 bits, no parity, 1 stop bit.   If you don't know how to do this and know a Cisco guy, we do this all the time to access routers and switches.

This is the output of my XE/G4.  I was getting the "black screen of death" and it was failing at the memory check (1024 Line).  I replaced the memory and I was back in business.

It seems like when I let the Amigaone sit for a few months, it won't boot and I have to reseat the CPU module.  However, this was not the case this time.  I hear about replacing the 2032 coin battery but that has never fixed mine.  I was looking on YouTube and there was a guy that baked his CPU module in the oven to resolder all the connections.  In his video it did fix his BOD.  I would only use this as a last ditch effort because when the solder melts in the oven, your components can move or fall off.

This is what is should look like with 1 Gig of Ram in bank 0.
