seeking 680x0-based Sun gear

Hi.? I'm new to the list, but have been collecting and restoring (mostly S-100 stuff) for many years.? Now I'd like to expand my hobby to tackle a 680x0-based Sun system.? I have some Multibus cards that I'd like to interface, and a VME-Multibus adapter if necessary, so I'm hoping to find a Sun-2 or Sun-3 system or parts to assemble into a working configuration.? I'm located in the San Francisco bay area but looking everywhere.? If you've got any related items that you might be willing to part with, or any leads that could be fruitful, I'd love to hear from you! (Another collector suggested that I might look for a Sun-4 VME chassis and populate it with Sun-3 boards, which seems like an interesting idea.? At this point I'm basically open to anything, but really would like to focus on a Multibus or VME configuration.) cheers, Shawn Neelymaxweb at pacbell dot net
