Definitely solder marks. When you put soldering iron directly on the tabe without any stand, sometimes it turns around and wreaks havoc.... or, just, these marks can be from soldering
I have a question for you, Codex.
My pal recently got interest in Amiga and started buying various parts over eBay for assembling.
Amigas were completely non-existant here, so he has a two very simple questions.
1) Can you use standard 5.25" or 3.5" FDD with Amiga or you need set jumpers/solder new terminator resistors like in old times of tinkering with ZX-Spectrums?
2) Sometimes accelerators for Amiga 2000 are sold.

Can you use them with A3000 and A4000? And explain why if it's non possible. Apparently, they completely replace CPU, right?
1, No, you have to to modify FDD to use it in Amiga. Not every model can be modified.
2, Those boards are generally useless for A3000/4000 because they are (in most cases) weaker than standard A3000/4000. Buy Cyberstorm 060 or PPC + adequate graphic board.

Definitely go for A1200 + Blizzard 060 + CF to IDE (2GB CF card) + CF to PCMCIA (another 2GB card) + CRT monitor (C1084S, C1085S, Phillips 8833II or M1438, which is the best monitor for A1200).
