Hi guys,
I had a bad experience last year when I bought Blizzard PPC 603e+ over ebay
and it came faulty. When I put accelerator into A1200 tower,
I have white screen and system stays hanged.
Kind Regards.
Not an all unusual thing with these boards especially the DCE reproductions (lower quality)
At the age these boards are invariably it's the edge connector and a power problem because of it. Brand new these boards are drawing the max across the A1200 edge connector for power and age, weak connection, corrosion on edge just makes things worse.
I would buy a wedge eraser and shave it down to the connector edge size to insert in and clean the orgiginal connector, also provide a beefier power suppply to the PPC board.
Do NOT use the original A1200 PSU. That PSU is just "barely" cutting it for the requirements.
If the above doesn't work then have the edge connector replaced as well the rest of the board checked out by a qulified electronics tech that is familiar with Amiga hardware.
I'm have the experience to verify your board but unfortunately I do not have any of the
AMP connectors and they are hard to come by last time I attempted a supply 3 years
ago.
