Well, the ideas of 'assembler' and 'standard' don't really go together in my
mind... :-)
But seriously, I don't know how many different PDP-11 assemblers there were,
but the two _main_ ones (DEC's, and Unix's) both use the same numeric
convention (although they differed in other ways, probably because of the
CTSS/Multics erase character convention): a sequence of digits is an octal
number, unless there's a trailing '.', in which case it's decimal.
(Well, technically, DEC had PAL-11 and MACRO-11, but PAL-11 was basically a
subset of MACRO-11, and used the same number syntax.)
I've never heard of that '&o' bizzaro-stuff - where did you find that?

Without going through the manuals at length, basically MACRO-11 supports
macros, and PAL-11 doesn't. The syntax is otherwise very similar.

I know it was used on ITS (although the PALX source had assembly options for
all the main PDP-10 OS's, except TOPS-10), was that where it was written, do
you happen to know? It's in MIDAS, so probably...

An image gallery of cheesy -- and cheese-cakey -- magazine covers from
what were for me the golden days.
But the UK mags weren't ever like this.
Some of the names, and the typos, are highly amusing.

OK, what was the standard (if there was one) number-base syntax for PDP-11 assembler?
Despite all the PDP-11 assembly info on web sites, this seems to be a buried bit of info.
One assembler doc uses a prefix of "&o", another specifies octal as default and prefix of zero for decimal (opposite of the common C-derived standard . . great).
Is this for example standard?:
BIT #&o200, @#&o177564 ; test 2^7 bit at address octal 177564
(I'm just trying to make some written commentary consistent with common policy.)

Same experience. I have some in a drawer on my work work-bench that
were purchased in the early 80s and they still smell.

In high school chemistry we did some experiments with that stuff. I
think the teacher just liked to stink up the school every year.
Now I also have a bunch of drawers filled with Allen-Bradley carbon
composition resistors from around 1970. All the leads have a whitish
film on them that has a peculiar odor. They've been in the electrical
lab at work, in an office environment since that time. I've always
been a little curious about what caused it.

I'm looking at a sample of what I see as a directory of sorts and am
attempting to decode the file names from it. They're not anything as
elegant as Rad50, but the encoding has escaped my weary brain.
The system in question is a Lanier 103 word processor.
Here are some samples. Can anyone come up with the encoding scheme? It
can't be very complex as this was a comparatively brain-dead system:
(All values in hex)
c4 a3 75 6a ab 52 00 00
5c 25 15 1b 4c 40 00 00
cd 6d 15 7a a6 10 cb 82
a1 7a c1 c0 00 00 00 00
94 2f 38 40 00 00 00 00
d0 7f 9f 12 25 fd 53 28
The recurrence of these strings in what appears to be a block directory
in the same position tell me that they must be file names. The file
data itself is in ASCII, more or less (special formatting codes). The
distribution of values to me suggests some sort of bit-packing algorithm
is involved.
Thanks for any suggestions.

A few months ago I picked up some Polycorp Polys, a computer designed
specifically for the educational market in New Zealand. One worked and one
didn't. The latter is now fixed. As usual I've written it up with lots of
pictures. If anyone is interested you can read about it here.

Folks,
Why does this keep on happening? What is google doing to cause this to
happen? Is it doing greylisting and mailman ignoring the retry-after time?
