SDF claims to have Altair BASIC running on a PDP-10. Maybe they have
both the source code and the 8080 emulator macros.
Altair BASIC would probably be easier to get working on an Altair 8800
simulated on simh.

Hi,
(First post, so go easy on me.) Perhaps what we have
is not so much the release of the 8080 instructions, but
the comments and, for what it's worth, the variable and
storage names. This surely gives an insight that a
disassembly, even an annotated one, just can't give?
Cheers, Brian.

Yes, in those days, magazines were printed, and mailed out, or shipped to

I thought about it long and hard. A fully configured Altair 8800c would be
at least $1200 plus shipping to Australia from all the different component
suppliers at least another $600. I would end up with a "real" system but
some parts wouldn't quite be real. For example the floppy drives are

revolution - at least in the US. CBM, Apple, Atari - the three big names in
home computers, all went with the 6502 family. And perhaps even more
importantly, so di
