Ok, for some reason I had in mind that this was a
drum. I actually have
that drive in my collection. Yours is in WAY better shape though. I
think mine sat outside in the elements for a while before I got it.
The surface is nickel-plated. Nickel is pretty rugged and chemically
inert relative to other metals. Even if it's got dirt in it and had
moisture/water, it may actually be usable, or recoverable. Don't rotate
it! The heads I think are ceramic and enamelled copper wire, electronic
stuff survives water pretty well unless there was dissimilar-metals type
electrocorrosion going on.
If I work out a recovery scheme, maybe I'll ask to borrow it, clean it,
power it up and recover it and give it back to you.
I found some marketing literature for it while
going through some documents at the Computer History Museum a while back.
I can make a copy for you if you like.
I would *love* to have copies and of course originals if available.
Copies would be fine, and if they're at the museum, maybe I can
photograph the covers for a sense of color etc when I come up for VCF.
