got a mono slab it worked for the first 4 hours then stopped, won't boot or anything, my thought is that it is the power supply??
Thoughts??
You might want to check the battery inside the station. If it's out of voltage, you can't boot the station, independent of the power supply. It's easy to get a replacement in an electro shop.
Cool, I will check it out later, what purpose does the battery serve? I would assume that it would keep the internal clock current, etc.. How does it stop the machine from working? Does it power any info in PRAM?
Seems that this is the same way that older Macs were designed and ocassionally things would go wrong then you would have to zap the PRAM..
Also, another question, I could not set the date past '99 on the machine, do I need the Y2K patch to be able to set the clock or could it be the battery that was on it's last leg?

OK tried a 123 Size Lithium 3V battery and still no dice.. Would it make a difference with the 123 size lithium vs. a BR-2/3 A 3V battery??
If it is not the battery, then the power supply?

Probably dried caps in the power supply or those choppers that are mounted to the copper ceramic pieces that break everytime you try to repair the power supply. You might try Ron Fronberg and see if he has any spare slab power supplies. I bought a couple off him a year or so ago.
The CR123 is a good substitute for the BR2/3A.

The battery is needed for the system to check, if the power key on the keyboard is pressed. No battery, no possibility to check for power key press.
Have you wiggled all the cables?, I have a soundbox that has a bit of a dodgy connection and does this. Try breaking and remaking all the connections.
From what I understand, you're saying the computer was working then powered down on it's own and failed to restart or you powered it down and thats the last time it worked?.
If the machine died on you, I think some kind of component failure, PSU or logic board/cpu. If it is failing to start up it could be a cable or battery or PSU.
As silly as it sounds and I have made this mistake, have you tried another appliance in the AC outlet in the wall/strip or whatever?, use a table lamp or something to test it. I once took a Linksys router back to the shop saying it was knackered when in fact it was fine and the socket in my house was dodgy.
QuoteHave you wiggled all the cables?, I have a soundbox that has a bit of a dodgy connection and does this. Try breaking and remaking all the connections.
I disconnected everything and then plugged everything back in. I also checked all power connections and the outlet. I also disconnected the Digital Ears Audio Input breakout box and alas... nada..
So, I guess that I need to isolate any other items..
I would assume that the power supply might be the culprit since I have read online that the Sony power supply is not the best in the beast. I am hoping that it is not the mother board, venelation to the unit it unblocked and is usually the reason the mother boards go bad.. or a short.
The box just stopped, it was up and running. No force power off or anything. I noticed it becuase I was pumping some MIDI into it and then the sound stopped while dumping a sequence from a synth, I thought maybe a buffer overflow and kernel crash, but I have yet to see a Midi buffer overflow kill a machine. Usually it will cause sound errors or keep looping but nothing more.
I am going to try and acquire a powersupply from the blackhole guys in Colorado and see if that fixes it...
While waiting to get the box back up and running will try and get a Color Cube ;)
Anyone on this board in the SF Bay Area with a power supply for a slab, let me know.
Cheers.

Your best bet as Blackcube said is Ron Fronberg, I got a spare slab PSU from him 5 or 6 years ago, (still have it). He bought a load of stock from the company that took over the spare parts business after NeXT stopped making hardware (Bell Atlantic or something?).
I think his eBay id is "ronfronberg" maybe a space between the two names.
Is it not possible that somebody could repair the PSU?, or at least test it, is there nobody on this board that lives near you, whereby you could send your PSU to someone and ge them to test it in their slab?
Yeah I saw this, half the links are dead when trying to email folks, there are a few available on eBay....
Got a new power supply and it now works!!
How do I get the machine to want to boot off the drive vs. trying to start off the network?
Cheers.
Never mind....

:shock:
Glad you got it working, very nice. I've had a few of the slab power supplies fail in the past. They don't seem to be the best for longevity. Have fun with your new NeXT box.
