   I am
suspecting a 2716 or 2732 too but...
 ... 
I'd be suprised if you could fit a reasonable BASIC interpretter into 2K
or even 4K of 6502 code.... 

Bizzare statement from you.  The 6502 was fairly code efficient and there
were
basics that easily fit in both 2k (integer) and 4k (with floats).

...
 There is/was an 8K*8 mask-programmed ROM in a 24 pin
DIL package (one of
the versions of the 2364 IIRC), and I wonder if that's what you have. I
can find pinouts of that ROM in the Rockwell databook if you need them. 

Yes there was Mask roms were available in both larger and less costly
for before the Eprom versions.
