I haven't seen this discussed before, nor mentioned in my Dead Mac Scrolls book

I have an SE/30 that was working just fine stock, but after installing a DayStar socketed 50Mhz upgrade and a MacCon PDS slot ethernet card, the screen is "twitchy"

The best I can describe it is that the screen moves down just a few pixels every few seconds and appears to be related to opening / closing windows. If I don't do anything, it's far less noticeable.

I checked the PSU voltage via the floppy port and it's a solid 4.93V even when I open and close windows, etc it doesn't waver even a hundredth of a volt.

I'd really like to keep these mods installed.

Any ideas?
