A1200T + BPPC (Resolved)

[Piru]

@Effy

Now was that really necessary?

[Effy]

I don´t like the idea that I would be somebody who likes to ripp off other Amiga guys. I always do my very best to make everybody happy and now it seems to look like I am the bad guy who did everything wrong, don´t like that. I prefer to think before I write, that´s why I haven´t posted so often in this thread though I followed it all the time !!

@nyteschayde

You really should do your homework before buying things like this. Check your A1200 motherboard and tell us which revision it is.

I'd bet that it is a 1D.4 or a 2B and as such requires some timing fixes to work with accelerators like the BPPC.

@Effy
I thought you would have known about these fixes? You might have been able to advise nyteschayde which A1200 to buy and saved this thread. He maybe a little stoopid, but that is no excuse ;-) BTW: Can you get me a nice cheap 1260?

[lorddef]

I had a 1d.4 mobo that refused to work with any accelerator (tried a blizzard 030 and apollo 030) until I did the timing fix on it. The timing fix on my mobo just required removing two caps, after that it was cool.

@nyteschayde Try not to accuse people until you're 99.9% positive it's not you.

Interestingly my rev 1d.4 A1200 worked just fine with BPPC, no mods required. Eventually I did apply to fix just to be sure though.

i had big issues with my 2B mobo the bppc did never work on it and i am just too lazy to do the fixes but the newest 1d4s are ok . Note that i have also had problems with amiga not booting. the whole thing can well be a timing issue as well as a power issue check you powersuply connection ! i had a power connection at 400watts not booting with bppc but fine with out was down to the connection that was verry badly solderd to gether. my board was a bppc 240\060 noscsi

Mine too :-/

 So, Blizzards are affected by these timing problems afterall. I thought that only apollos and some other cards has problems with these Motherboards.

[nyteschayde]

It's ok. If Effy wants to play that game thats fine. His response stemmed from this last email I sent him (below). He is worried that I will try to further discredit him. I did ask for help here because I am having trouble.

I am upset because I have spent so much trying to get this working. Anybody who has spent 500USD on Amiga parts just to receive a non-working unit would be equally upset especially if the seller's only response was to say, "Keep asking people, I am sure you'll get it working."

If I can get it working thats great. You're all right that I wasn't aware of any timing issue. I'll take photos of the board and continue trying new things as I indicated in the email before I further discredit him but not once has he come close to stating he'd return the money. Based on his actions I doubt he will. Even though it's something I'd do. I didn't want to sell the BPPC before ensuring it worked for that very reason. Which is why I went through the process of purchasing an Amiga 1200T to test it with.

I have noticed that of all things you don't seem very upfront about guaranteeing your purchase. Did you sell me a broken accelerator? Because it was broken when I received it... If this cannot be resolved I can be sure to make sure that others know you won't make good on your sales and that nobody should trust you with purchases. I don't mean to strong arm you but you walked away with my money and I got your broken BPPC. I will keep trying a bit more before I let everyone know but I am not exactly happy with your stance on the whole thing.

Ho !
It reminds me about a f**** 420W ATX PSU that could not give more than 4.56v (for 5v) when it was in loads, so it could not boot my BPPC, and makes crash my PC ...

And also the old 140W AT PSU that give only 4.86v on my 1200PPC+GREX+tons of hardware and boot 1 times about 10...
I replace it by a 230W AT PSU that give me 4.96V (for 5V) and my machine works very well  :-D

So I suggest you to check the voltage on the PPC FAN, if it's under 4.9v you 'll have lots of problems to start your machine !

So check all the voltage  :rtfm:

Nyteschayde : I don´t mind dragging the subject to this forum, but to be honest you forgot to add my answer I gave you yesterday :

"hi Gabriel,
           I know for myself that when I have a problem that I can not solve that I ask for help at Amiga.org, just like you did. Check out their answers.
 
greets,
Effy."

So far I have not only seen possible answers to this problem, I have also learned answers that I didn´t know yet.  But it worries me that you seem to be so sure that the card won´t work, even when you get different possible reasons from people that have more experience in these things than you and me together  :-o

[nyteschayde]

Ok, so here are some pictures of the mobo. It appears to be a 1D4 model. But on the url supplied above, they mention only a Budgie Rev 01 and Budgie Rev 02 fix for 1D4 mobos. Any ideas on which model this is? It seems to be a Budgie Rev 0.



And the BPPC card with and without RAM

[CLS2086]

Hi,
and what about the voltage ? I'm still waiting for your answer !!
Try also to look at the Quartz and under the 68k CPU if their pins are well solded. I had this problem in time  :rtfm:

IIRC, my mobo is similar.  I always assumed that the line below the Rev 0 indicated the real revision - i.e. Rev 01 in your case (this is the same as my mobo).

I forget if Escom updated the copyright on the mobo - possibly not.  It's just that the A1200 HD sticker looks the same as mine - i.e. a post-1995 Escom A1200, rather than a Commodore one.  I mention this because my mobo is an Escom version, revision 1D4.  I remember checking the mobo fixes out long ago, only to find that Escom had apparently already performed the 1D4 fixes at the factory.  So, it's worth checking the component numbers on your mobo to see what is there on your 1D4, since an Escom 1D4 is not necessarily the same as an original Commodore 1D4.

It is a 1D.4 motherboard.

Unfortunately a badly worded help page, due to poorly numbered chips! There were two budgie chips: Budgie Rev 0 (part no. 391425-01) and Budgie Rev A (part no. 391425-02).

You have a 1D.4 motherboard with a Budgie Rev 0 391425-01. You follow the instructions on that help page marked 1d5 Budgie Rev1. I think you can follow from there?

[alexh]

I have to say that looking at the photographs of your BPPC you can see that it's had it's two crystals replaced AND the Zero Ohm link jumpers (clock multiplier settings) changed sometime after it was sold (i.e. neither are factory issue)

Pressumably these mods were to overclock both the 040 (33MHz) / 060 (66MHz) and PPC (266MHz).

 Just looking at the soldering work you can see it was not done to.. lets say.. "the highest" of standards. Not only did they not clean up all of the PCB resist with some alcohol afterwards, you can see where they accidentally melted part of the plastic on the top of SIMM socket with the soldering iron when they were doing the mod :-)
