Yes, it's very unlike most of what's been done since. Some of it (e.g. a

good stuff there yet to be mined.

Ooops, it was Roger Schell, I get them mixed up all the time. His oral

is a Must Read.

What I found about that mostly talked about the belt stuff. Do you happen to
have a pointer to the segment/call stuff?

Ah, what were the issues (if you happen to know)?
