Hi Steve,

I don't mind - glad to see someone makeing use of the code.

Btw, in case you have a version of ALPS that I posted to my commercial site some
years ago - about a year ago when I did my "Altair preservation project", I dug
into the ALPS sources, cleaned them up and fully commented them - I also found a
much improved version I had done of the debugger and updated it as well. These
updated sources can be found in my ALTAIR simulator disk images, as well as the
ALPS N* image that I just posted through Randy's site:

I never did update the ZIP on my commercial site - if you don't want to be bothered
with trying to extract them from the simulator images, just email me and I will send
you the updated source files.

I also have Micro-Basic - a tiny (3K) BASIC for the 8080 --- obviously not as
powerful as MS-basic, but a cute little way to demo a system (You can try it
out if you boot my "DMF" OS under either Altair or Horizon simulators).
