Dead Apollo 4040-4060 turbo Card -- Help!!

[Palm]

I have aquired a Apollo 4040-4060 Turbo A4000 acc card. It has a 50Mhz 68060-RC50A CPu and a 66MHZ Xtal. I have gotten it to boot into early startup ONCE(!).

I have checked it for shurtcircuits. All semms ok (visually).
I ahve both jumpers on motherboard to INT/INT (J100) as the manual states.

The Amiga works fine if I insert my Warpengine 040-40 card.

What happens is:

1. I insert the card properly in the slot
2. I power up

What I see is that the powerled never goes from halv-lit to full-lit (as it should with about 0,5 sec delay). It kind of just hangs there and never boots up.

So, i was wondering

a) any tips ?
b) who can repair it for me ?


BTW: Since it actually booted up once! I believe the CPU and xtal to be ok.

The jumpers on the card are set correct. It is set to 060 mode on the CLK jumper, and set to C60 on the jumper beside the ROM chip.

Anyone who has had similar issues with the card, I would be VERy happy to hear from you.

Well if the CPU is 50MHz, shouldn't the crystal be too, at least to start off?  I'd stick a slower crystal in there, it will probably run even if the slower crystal underclocks the board a bit.  But I suspect it came with a 50MHz part from the factory.  I'd try that first.

[Palm]

Hi. It is said that this is a RC50A version of the CPU which means it should run fine with 66Mhz. It was written in some post somewhere that it could also run at 80Mhz (!?).

However, I tried to take the xtal out, and the card was as dead as before. Maybe it is a defective xtal. I really dunno where to get a 66.000000MHz xtal. Probably have to order it at a high price (!?) from some company. (elfa.se ?)

Thing is,  I don´t have another 50MHz xtal to test with. That kinda sucks :-)

BUT: The CPU gets warm when the machine runs, so my guess is that this means there are cycles going on ?

Anyone ??

[alexh]

For it to run at 80MHz it has to be a version 6 68060 with an E41J mask and you need 50ns DRAM. Then there is only a very slim chance the Apollo will like that speed.

Is the Voltage regulator board connected correctly?

Check all jumpers on the accelerator itself.

[Damion]

Is the CLK jumper near the oscillator set to 040? (It should be with an overclocked 060.)

edit:

It is set to 060 mode on the CLK jumper,

This is probably why it won't boot. Set to 040 and try again. (Or leave at 060 and go back to a 50MHz crystal.)

[Palm]

Hi Alexh: I only plan to run it at 66Mhz as the xtal says. no more...although, less is fine...060 is cooler than my old 040 board so I will settle for 50Mhz if I have to hehehe..

The regulator is connected ok. I have checked it. The regulator-transistor gets slightly warm, which I guess means it probably works. Also, since the card did boot once a while ago intermittently, it cannot be totally broken :-)

Hi -D-:  I do not have a 50Mhz xtal. Maybe I can order one and tryit out. However, I think this card came with a 66Mhz xtal.

My 040 Warpengine card has a 50.000Mhz 4pin xtal on  it which I can solder off and try. It is in a black plastic IC package, and not in the shiny metal-package the 60.000Mhz xtal is from the 060-card. Will it work to test with this 50Mhz xtal ?

Setting it to 040 still doesn't do the job, I am afraid. still same symptom (powerled doesn't get fully lit after power-on).

I guess the xtal has to be 4 pin package ? Is there some kind of regulation on what type of xtal it is ? Most 4 pin xtal packages today seem to be SMD. If it is all the same, I can just solder legs to it to mount it into the xtal socket on the 4040-4060 card.

I wouldnt break your 040 WarpEngine.

Just get an xtal off ebay or AmigaKit or somewhere like that... wait a bit.

Check your stand-offs make sure they are the right length and their is no loose connection on the CPU connector

[Palm]

Hi Alexh,

I will search for the xtal. However, I am not quite convinced that this is the reason why it does not boot up.

If by stand-offs, you mean those two plastic-poles which the card rests on, then they are ok. On this card (as opposedd to the warpengine) only 2 are required (as there are only 2 holes in the PCB. They are both in place. And I have also checked that the CPU SLOT connector is properly connected. I can "feel" with  my finger alongside the connector that there is no gap. I have felt how it is when my working warpengine is connected too, just to compare how it should be when things are fine :-)

This is really killing me. I got this card for free, and if it works, then I will be happy. But if I have to repair it, then I would maybe prefer to buy something else..maybe a ppc card or something since I have a elbox PCI board which I desperately wants to buy the mediator-card for so that I can start using PCI cards....then I can sell my Z3 card...hmm...to buy maybe a PPC ...mmmmmmmmmmm......PPC....armmmmmmm... :-)

[color=ff0000]UPDATE:[/color][/u]I did buy a new 50.0MHz xtal 10 mins ago from the local amiga shop down the street. It did not boot now either, when I set the CLK jumper over to 060 (as it probably should be when 50Mhz "normal" xtal for non-overclocking is used.

However, I did see that the MACh chips has "66" written on them, and this makes me wonder if this card has been upgraded with new 66Mhz MACH chips, hence the 66MHz Xtal.

Any suggestions ?

Not any to help but i did have an Apollo 1240 that died in the same way.  I also got a new crystal but never got it fixed. I was told the CPU was dead and could be replaced if you have the solder skills or tools to do it.

[Palm]

Hi. The CPu is on a socket, so that should be easy to replace if I find a spare CPU. However, I dont wanna spend too much money on this card as I am told Apollo cards generally stink a little. :-)

If someone wanna buy it, along with a CV64-3D w/scandoublermodule, a 16 bit SUNrise soundcard and a MacroSystem VLab 1.3 I will happily sell them to finance a Mediatorboard for my A4000 so that I can use cheap Voodoo gfxcard and PC soundcard which cost close to $0 :-)

£50? for the dead Apollo. You can keep the 060 chip.

Hi

Are we talking about this card...

If so they can often conflict with the slightest thing. I have had a number of problems with this card particularly with PCMCIA devices and possible power issues. You either get the dim light or even a flashing light. You will note from mine I have the bit of paper under the power modulator.
Sorry if I missed the point or got the card wrong. As I say, may be not the card at fault.

Here is a link to a PDF of the card from my site

We are NOT talking about that card.

1240/1260 ! = 4040/4060

You're out by 2800 ;-)
