Default PPC problems
Hi!!! I friend of mine has a PPC 060/200 card. It was working ok until he had to reset 2 or 3 times the machine in order to work. Until one day, when the machine woulnt boot up at all. We changed memory, the machine boots but at the early startup menu, board is not recognized.
We did a flash update, but the same thing: board doesnt work and is not recognized by the Amiga.
The chips are hot, the cooler is working
Any suggestions before we send the card to France??
Its a Phase 5, not DCE, with scsi.

Cheers
Sebastian

I'm afraid to say that those behaviour is common in old ppc cards. Maybe it's near to his end. :-(

its difficult to say!

Have you already tryed to clean the edge connector and/or try to fit the BPPC NOT fully inserted? (1-2 mm out)

EDIT- ah . . which PSU are you using? and would be better to test it on another A1200. (before sending it for repairs)

We tested in a full Tower (250W PSU), with 2 different memory modules (with 64meg it wouldnt power up, just RED and/or BLUE screen). With the other 32 meg simm i have, sometimes we got so far as opening screen of WB, but it wouldnt finish loading it up

In my desktop 1200 with an A500 PSU, sometimes black screen, sometimes nothing at all...

I guess its complicated to diagnose this, uh?
So, we tried in 3 different machines with different configurations...of course we tried every single possible combination...

:-o

it "seems" a lack of power on the +5volt rail. (worse with the 64MB module)

The last test you can do, is to feed the +5 volt and GND directly from the PSU to the CPU fan socket.

But honestly, i prefer that someone else (who has already done it) could confirm this "dirty hack" :-)

That little fan socket trick/hack will work , at least in the short term. Visually, the power led will be nice n bright , just like if no ppc card was connected. On the downside, the fan connector is unlikely to work again as a fan power output and eventually the extra power will eventually appear not to be helping much. The chips do get fried (er...hotter) with this extra power direct to card.

ah yes for sure!

That dirty (yes because it is) hack, will generate a ground loop at least (if not worse without an appropriate circuit).

In most of the cases, it will work but . .
