Got an A1200 motherboard with what appears to be repaired traces on the bottom left corner. I have to reseat roms and tap the machine every once and a while since it resets or acts really wierd. (garbled graphics, sudden loss of memory, resets, garbled graphics in early startup menu).
My previous A1200MB worked fine before I ruined the IDE header, so this behavior isn't due to quirks in my configuration.
When I emailed them about this they said the motherboard they sent was in working order.
Well yeah it works, just not 100% of the time. Could see how they could have pushed it through as you have to use it for a few hours to see catch the problems as they're sporadic.
Can't advise a refurb motherboard purchase, but I intend to order from them again for some future equipment.
