Heya folks, I'm trying to get a Quadra 610 into shape for 24/7 operation, and could use some advice on getting it running reliably.
So far I've maxed out the RAM and replaced the HDD with a BlueSCSI, which is running A/UX 3.1.1 without a hitch. Replaced the 68LC040 with the real deal and pulled the PRAM battery. However, trying to fill the empty VRAM sockets out with new 256k SIMMs from Siliconinsider I ran into my first issue:
Running at any higher resolution or bitrate that would require the increased VRAM leads to consistent corruption on the lower half of the display. That's not a big deal for my use case, but makes me suspect a recapping may be in order. It could be the SIMMs themselves, but I'm not really sure how to discern that, and they are brand new. Dragging a window into the corrupted segment of the screen, then back up to the 'clean' area causes the window to continue drawing the garbage from the bottom half of the display. I've also noticed it only recognizes the additional VRAM at all if both slots are populated, though I don't really know if that's expected, or indicative of an issue. No visible change when swapping the two SIMMs between sockets.
As far as recapping goes, the board seems to be mostly tantalum caps. Are they worth replacing before they give me any reason to, or is it best to just stick to the few electrolytics? Worth cracking open the PSU? Am I overthinking, and it's probably fine to leave running as-is?
Cheers!
