I had a lot of problems with my SE/30 network card from Sonic Systems recently. Sometimes it would work, with the LEDs on the NIC and switch both lighting up, and sometimes it would just not work at all. In some cases, the connection LEDs would randomly flash on and off, without any network traffic going over the line.
Then I found out that some of the solder points at the back of the connector card would make contact with the SE/30's metal chassis. It didn't short the board causing it to fry or anything, it just created an extra ground, causing the card to simply stop working. When I pushed the card aside a bit (as far as the outside casing allowed me), the solder points lost contact, and the NIC would work again. Now I just have a piece of plastic wedged between the solder points and the metal chassis to isolate the two. It seems to work fine so far. This seems like a big design flaw from Sonic Systems, but on the other hand it's understandable that such a thing can happen when you have to screw a logic board to a metal chassis. It's more a result of Apple trying to cram an expansion port inside the compact Mac's already cramped innards. Maybe your cards have similar problems. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Vintage Macs group.
