There were 2 3000-series families, one known as "lower 3000"
(3100/3300/3500) and the other as "upper 3000". (3600/3800)  I never had
any direct experience with them, but I recall that the lower 3000 were 24
bit and the upper 3000 were 48-bit machines and had the "Forbin Project"
blue-glass styling.  Most of the CDC 6000 unit record equipment (printers,
card readers, etc.) was designed for a 3000-series peripheral interface and
hooked to a 6683 channel adapter box.
