Thanks Paul. I found an srec2bin converter and ran
that.. it created a 1K

readable strings.
Not too surprising, since AFAIK the basic Dynamicro doesn't have any ASCII
I/O. Next step would be to run the binary file through an 8080 (or Z80)
disassembler. I use z80dasm, which is provided as C source code:
https://www.tablix.org/~avian/blog/articles/z80dasm/
but there are many others to choose from.
Without the disassembler, just looking at the object code in hex, you might
see whether there's a pattern in the first 64 bytes of each 8 byte group
containing a few bytes of code then zeros. That's common (but not
universal) in 8080/Z80 code because the reset vector is at address 00, and
the RST instruction vectors are at 00, 08, 10, 18, 20, 28, 30, and 38
hexadecimal.
