Back to the original topic. So after the wash the Mac worked fine for 2 days then started giving the simasimac increasingly frequently and now it's back to not booting any longer, sitting at the zebra screen. I went around my new caps and resoldered a few, also I did solder the replacement RP2...

Btw, regarding supplies of the RP2 Bourn filter 4120R-601-250/201, I saw Quest Components appear to have them for $3/pce (2-8 units), minimum order $25. I didn't order since I could recycle one from my old board but probably worth it if you plan on servicing a couple of Macs.

Update. This is a good one. I ended up replacing the Bourn filter RP2 with a replacement I plucked from a dead SE/30 board (my first experiment with replacing the caps a couple years ago...) pretty much like Phreakout described. Excruciating process, took me a good hour just to extract it. It...

No luck. All the caps are solidly soldered and I checked there's good contact with a continuity tester between the cap and the back of the board. Has anybody experience replacing the Bourn network filter RP2 and successfully cure simasimac?

Hi. I'd like to get some input from the experts out there. I got a SE/30 showing terminal simasimac symptoms (horizontal zebra stripes). Following the common advice I replaced *all* the caps C1,...,C13 on the motherboard and still get the simasimac. Pursuing further based on the recommendations...

Victory! I got the problem fixed. The schematics got me started scrutinizing the motherboard and I found out that capacitors C6,C9 and C10 had been leaking. I replaced the 3 of them and, miracle, the reset is now fully working again. Thanks for all the pointers and the schematics, it helped...

That's what I feared... this one will get solved the hard way... I was secretly hoping somebody would post a reply like "it-happens-to-me-all-the-time-all-you-need-to-do-is-replace-component-xy34" I'm torn. Since this is the only (and minor) problem I have, I'm not sure I feel like raiding all...

I've been using the switch regularly (like a couple times every week, mostly because of Netscape 2.0.2 hanging now and then). So I immediately noticed when the switch stopped working. Initially I suspected the switch itself. I desoldered it, measured the resistance across the pins of the...

Hi. I signed up to the forum as I could not find any cue on the web for the following problem. I have an SE/30 that has worked perfectly well for many years until recently when I noticed that the Reset button (next to the Programmer's switch on the left side) had no effect anymore. In details...
