The databook indicated that the 1801 is a two-chip
set, which consists of
the CDP1801C and CDP1801R, the former containing the control circuitry and
that latter containing the registers. Apparently RCA designed it as a
production prototype, and did not intend it for commercial use, instead
recommending that customers design in the 1802 which was due out soon
thereafter.

That's not inconsistent with what I wrote. Rad-hard parts are not considered
"commercial" use.
