Thanks RichA. Does any of the original UUO interpreter
code (with the
exception of the missing DDT code mentioned above) survive in a
publicly-available form?
Hi, RichC,
I'm afraid not. The original code is the private property of Paul Allen,
though Microsoft used later versions in its language business for many
years. (A friend of mine was the maintainer/developer of Microsoft's
tool chain back in the 1970s and 1980s. He appears in the famous picture
of the team from Albuquerque.)
We have talked to Mr. Allen about the possibility of making this available,
but he has not responded either way.
He used the simulator and original source code to create the Altair BASIC
which he demonstrated during his interview with Leslie Stahl on 60 Minutes,
so a working copy (other than the DDT) does exist. We'll announce its
availability, when and if we get permission to put it up.
