CSPPC BOOTUP

[Miloo]

Ive had my CSPPC for about 3 months and it rarley boots up first time, it usually takes several attempts before the thing decides it wants to boot.

How many PPC owners have the same problem?
Is it a case of the age of the hardware?

I think about 3 possible problems:
-bad contacts
-bad contact in the cpu socket (bad solder point)
-bad PSU

[quenthal]

Those three are the most probable reasons. I had similar problems with my CSPPC, and all of those were caused by bad contact between CS and motherboard. I removed CSPPC, cleaned the contacts with eraser and some contact spray and replaced the four original spacers with plastic/nylon screws and bolts and everything has been ok since.

Ive cleaned the mobo, made sure nothing was shorting out, every connector, slot and removable chip and put everything back together and guess what - the machine will NOT boot at all.

I put in an A3640 changed the INT/EXT pins and still nothing. Im going to try and get an A3630 and try that as well to be sure.

Im really gutted as its only just come back from France from having the clock fixed :madashell:

Ive run out of options now so if anyone has a spare working 4000 mobo (pref a CR, REV D) they want to sell I'm interested, otherwise I may start to sell it all off and get a PS3.

dont do that you will regret it, aos4.0 is around the corner now!!

Best thing to do in this case is just relax.  Put the Amiga in a corner somewhere and forget about it.  Get dinner, see a movie, take a nap, whatever..  Wait 24 hours then, when you're calm and collected then go back and get the Amiga.  Reseat all the cards once more and your Amiga will work again.  Works every time.   Its called Amiga Yoga.

UPDATE :

I put the EXT/INT the wrong way round, the A3640 does work and I can boot into Workbench, so that means the CSPPC card is dead and was dying! :boohoo:

Push gently the 060 processor down into it's socket.
If it boots while holding the pressure it is the most common problem off these turbocards.
In the past I made a bracket to push it nonstop against it's socket.
Worked allright but that was in a tower but guess you could do the same in a desktop.
It still needs to be repaired once but you can save up some cash then.

Check out your scsi chain. If the scsi cable is bent that may prevent booting. Do not lose the faith! Check out your ram modules. Press ESC key and see if that works.

Never ever push on top of the PPC chip. You can press slightly the 060 chip but please be *very* careful. Don't try to save money making strange tricks to keep the cpu pushed against the socket. If you see that applying a slight presure your computer boots you should thinka bout carrying it to an experienced technical service and ask them to resolder the cpu socket. Remind them that the cpu cpu socket is SMD.

But I hope it's not a big problem and you can resurrect your board. Don't get nervous and be patient. Speed kills so take it easy, discharge yourself from static electricity before touching your miggy and take out all the cards but your turbocard.

It just doesnt want to boot, I have just the CSPPC installed and a Voodoo 3000 - nothing. Im going to send it to France and hopefully it can be saved :-(

[Miloo]

If the PPC cpu was defective would it still make the machine not boot?

[amiga92570]

try it with both terminators on the scsi cable and see if it will boot off the workbench floppy. If not send it to me and I will check it out :lol:

JJ B said he thinks he can fix it for 220 Euros, I'll try and find out whats wrong with it.

[Framiga]

looking at the price, i bet on the 060 socket! good luck :-)

ah a suggestion ... don't use/start it anymore until is fixed
