Thanks Dwight. I call it "digital archaeology". Doing a little more work on it
today, trying to see what responses it might expect from the remote system. I
did find specific text strings that have "CPM" in it, so my theory about the
origination is probably right.
I'm hoping to use some "six degrees of Kevin Bacon" here...maybe someone knows
someone who knows. I may post the edited listing file at some point.

Subject: SCP/Microsoft 20HAL uploader
All –
I’ve done a quite a bit of work with my Seattle Gazelle,
and I just did some work on 86DOS.SYS (not released in source form, as far as I
know) and its comparison to PC DOS 1.0 (at the code level, a very high
correlation as you can imagine). Partially related to that is a program called
“20HAL” which was a code uploader Microsoft used in the late stages to get code
from Microsoft in Bellevue to IBM in Boca Raton, FL. I did a little write-up on
it here (http://www.classiccmp.org/cini/hal.htm)
There are some holes in the analysis – I think it’s pretty
close, though -- but I’d really like to get some more details on it.
Unfortunately, it’s 40-year-old code at this point, and how many people
remember how they used a file transfer utility that long ago?
Anyway, enjoy the read. If anyone sees any corrections that
need to be made, let me know. Thanks!
Rich
