Anyone with a working Quadra LC 630, Performa 6200-6300?
Posted by: nzmacuser on 2025-12-16 21:53:16 Hi, Can someone with a working Quadra LC 630 or Performa 6200-6300, please tell me if it will still post without the front LED/infrared/volume control unit plugged in? I just wonder if mine has developed a fault. Thanks.

Posted by: Nixontheknight on 2025-12-17 13:24:18 Yes. View attachment 93363 View attachment 93364 With original capacitors even! 🤣 oh wow, my 637CD, 6214CD, and 6300CD all have their original caps (to my knowledge with the 6214 and 6300)

It turns out there was some corrosion on the contacts of the Cache Rom slot which I didn't initially see. This slot sits directly below the fan/enclosure, which had a bit of rust on it, so might explain where the moisture came from. I sprayed some contact cleaner on the slot and inserted/removed some thick cardboard 30+ times which seems to have cleaned it up. Now the machine posts. 🙂
