I get random freezes and errors. Sometimes doesn't boot up properly. Some times have some single pixel vertical lines when it hangs. Seems to be able to make it occur by wiggling SCSI+Floppy ribbon cables or have some shock motions (like inserting a floppy or tapping on the case)

Hi, recapped the logic board and Mac works great other than date/time and PRAM doesn't survive power cycle. I have the revision 1 board (http://www.maccaps.com/MacCaps/Capacitor_Reference/Entries/1991/10/21_Macintosh_Classic_II.html)
I unfortunately lifted the solders pads on the logic board...
A little repair history
- Changed out all the leaky caps on logic board 10 years ago. Replaced the battery. Everything worked great except doesn't keep date across power cycle (didn't before the repairs). Never found the problem.
- Messed with it 10 months ago. A friend has better soldering...
Took apart my Classic II nearly 10 years ago for repairs. It had no sound and RTC didn't keep time across power shutdown. Back then I replaced all the chemical capacitors (a couple of lifted pads/traces with some wire repairs) along with a fresh battery. Sounds came back, but RTC still lost...
Mac Classic II capacitor replaced, boots up fine, sound works (was faint and then silent after I washed the motherboard), keyboard+mouse works, SCSI works. Battery also replaced.
It won't keep time after a power cycle. If I restart the computer, the time is kept there is no interruption in...
I've got low audio and boot issues. Cleaned the board and now boots fine. Of course low audio issue is still around and definitely bad caps.
On the Classic II, there are a couple of capacitor in tight spots without too much room around it for a soldering iron tip. I've also read the traces tend...
