There's a chance that the Sun 4/260 in the collection was once mine.
I had it between about 1993 and 1997, in Mountain View, CA. I
eventually grew tired of the noise and bulk sitting in the dining room,
and offered it to interested parties. Barry came by to pick it up,
along with the Fuji tape drive, and a loose SMD drive or two, plus the
4119 color monitor and about 50 feet x5 coax to put the monitor far
away. He had an online museum that he was going to put it in, somewhere
in the Santa Cruz mountains.
I don't see the SMD controller in those 4/260 pictures though, and I
didn't take the SMD pedestal when I got the whole machine in a fire sale
for five bucks.
I'm pretty sure I don't need it back. :-)
