[SunRescue] note on living expenses

[rescue at sunhelp.org]

   IIRC, the Sky boards had a big Weitek chip on them. They existed because
the 68010-based Sun-2's otherwise had no FP hardware at all, unlike the
Sun-3's which all had at least provision for a 68881/2 if they didn't
come with one stock.

   There were VME Sky boards -- it was a 6U board that went in a 6U-to-9U
converter (that might also have memory onboard) that was also used for the
"Sun-2" SCSI boards.
