I have a huge resolution of the amiga colored checkmark. I think it was close to 2235x2480 done in a PSD file (8MB total size). There are a few elements that I would have to strip out of it before I would let you use it though. Also, I would probably convert it over to a 24bit PNG w/alpha removing any layers. One of these days I will convert the original logos over to SVG or EPS for full scaling without loss of quality... but that won't happen for a while. When I get off work today I'll convert the graphic over for you and send a pmail your way on how to get it.
I also have other high resolution graphics of the original logos including the original 16x8 boing ball found on the A1000. The only logo I can't give to anyone is the AO logo... that stays within the core developer team.
