[BC] Providing schematics

[Bob Groome]

Seems that not too many years ago DBX would also
not provide schematics. Generic stuff inside,
they were, I guess, protecting how they had
figured out to make those parts do a nice job of
audio processing. I had an early CRL that had
schematics, but some of the IC's had the part
number scrapped off so you did not know what was
inside it to help protect their designs.

Kind of a mixed bag for a manufacture to protect
all their design work and yet help owners keep 'm
going. With almost all the current stuff being
computer based; an EPROM holds all the secrets
now.
