Thanks Ethan. I found all my docs too and after discovering the SRAM
had died on my little board and fixing that, I've now captured and saved
the ROM image here,
https://drive.google.com/file/d/0B6A73VHTVh23N3IzY2VPUzRteHc/edit?usp=shari…
The top of the capture lists the three line program I used to capture
it,
10 FOR I=0 TO #09FF
20 PRINT I, @I
30 NEXT I
followed by the listing (in decimal obviously) from 0 to #09FF where the
ROM lives.
Have fun!
Chris

And in the case of INS8073, I can do this too.
It has been a while
(like, oh, 30 yrs) since I have played with that micro so I'll need
to remember how to find / access the ROM.
ISTR ROM is 2.5K of the low 4K of the memory map. 8073 Tiny Basic
also uses "@" in place of PEEK() but I don't recall if it returns
valid results in that address range or if it's blocked (CBM BASIC 1.0
used to block PEEKing of BASIC ROMs).
