Tom:

        Thanks. I actually examined the manual a bit more closely this time and
found that it included a small loader. Dunno why I missed it the first time.
Bit rot no doubt...

Have you examined the data on the tape? Hex/ascii formats are easy to
decode, and binary ones are usually pretty trivial. They are almost always
something dumb like:

leader leader leader...

flag character or sequence
record type (1=data, 2=start addr, 0=stop, that sort of thing)
load address (2 bytes)
byte count (1, 2)
data....
checksum

more records...

ASCII vs. binary, even, would narrow your choices.
