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
