Does anyone have any B8500 or D825 documents?
D-Machine?

There was also a B8300 for a TWA(?) airline reservation system,
anything out there about that?

I am also interested in IRE Journal articles about AOSP (the 825 OS) and
early Burroughs floating-point arithmetic.

Thanks

Not that this helps you any, but I forwarded this to my older brother,

The D825 was quite a different machine from the B5500. I remember there was
a paper on it in one of the {Fall,Spring} Joint Computer Conference
Proceedings.

I once had a nearly complete set of Air Force technical orders on the
machine - it was known as BUIC for "Back Up Interceptor Control".
I gave the TOs to a fellow who was working for Nick Tredennick, so
he might still have them.

I have here a "8500 System Reference Manual". Please
contact me by email if you want me to do something with it
-- though I'd be reluctant to post it overseas and I don't
have access to a scanner. My email address isn't hard
to work out.

(PS - I'll be away from Monday for 3 weeks and out of
contact).

Cheers, Mike.

I also have a copy of 3 manuals for the 8500. Do you live near the Computer
History Museum?
I would be happy to donate the manuals to them if they do not have copies.

I did have a copy of the D-Machine manuals, but I may have given them to the
CHM already.
