I've never seen "NIBL BASIC" ported to 8080, that would be interesting.
the 8073
is a SC/MP derived cpu family member so nibble on that is developed code.

The 8072 was a custom part where the customer would develope code and
have National massproduce the part for a specific application.
Is the INS8073 the one that has a Tiny BASIC
built-in or runs out of
a ROM ?
Yes.
Is it a Tom
Pittman type Tiny BASIC ? Thanks.
How does one tell?
It's in 2.5KB of ROM, so it's definitely a tinier BASIC than in the
competing Intel 8051AH-BASIC and Zilog Z8671, both of which had 4KB of
ROM.
National called it "NIBL BASIC", although it is unclear how closely
related the 8073 version is to their NIBL BASIC for the SC/MP, SC/MP
II, or 8080.
