Q: On what platform was Microsoft BASIC 1.0 written?
Umm, which Microsoft BASIC 1.0? If you mean the productized BASIC for
the Altair, then a PDP-10 (KA10 CPU) in the school district offices in
Albuquerque, New Mexico, on which Micro-soft Corporation rented time.
If you mean the original version for the Altair, there was no Micro-soft
in existence at the time, and that was written on a KA10 at Harvard
University. Both systems ran the PDP-10 10/50 Monitor, probably a 5.0x
release given the dates in question.
What was written on the label of the tapes written on
that machine?
Things like "LGP1", "WHG", and the like. Absolutely no clues as to
the
contents at all.
By the way, these were DECtapes, not 1/2in 7- or 9-track sequentials.
I've held them in my hands, and read the contents on a TU56.
If you mean some later product, I have no idea.
