Maybe it would be a good thing to make that timing fix, anyway.
I had problem with a1200 for YEARS. It would freeze if used 15 min after cold boot. But if left alone, after 15 min, everything worked fine. So I did the timing fix, although it was a "long shot" and VERY unlikely solution. Surprisingly, A1200 works now. It has some minor problems, like when exiting YAM system crashes and screen gets blue (custom chips), but its much better than before. :-)
