Yes. That was apparent from the fact they printed this MCS48 catalog.
National made an extension on the 8048, i.e. the 8050, and the 8035 in the
form of an 8040. It had 256 bytes of on-board RAM, but otherwise pretty
well compatible with the Intel parts. They pushed it pretty hard for a year
or two.

(INS8155,56)
among my parts.
The NS8156/55 were introduced a year or so later.
would appear together with products coming from
device families intended
to replace the MCS-48. It must have lived within a fairly narrow window.
National did the 804x for a while.
NEC and a few others made the 8155 and '56, so
they might have made a
version of the 8154 as well.
They did not. the 8154 was an oddball part.
