now, back to something on topic...
picked up an unenhanced //e system for $10. a bit dirty from no use and a
broken shift key, but powers up fine. came with 2 floppies, monchrome display
which needs the contrast control cleaned and the ever popular system saver.
this one has a hayes micromodem //e whereas the ][+ i got last week had a
micromodem II. besides the way they connect to the phone line, are there any
major differences? i presume both are still 300bps.

I'm not sure how you did the arithmetic :-) 4KW (8KB) is used for the "I/O
Page" which *includes* the boot PROMs. Stack can be anywhere.

Because the DDD DDD specifies a register (1 of 8) and address mode (1 of 8) to
use. So, you'll often see something like JMP @#0173000, which is represented
in two words 000137,173000. In this example, the address mode is 3
(auto-increment deferred, deferred = indirect) and the register to use is R7,
which is the PC.
So it means "jump to the address given in the word the PC points to". In other
words, that's how you code an absolute jump. The reason for the auto-increment
is that that mode is the general way of getting immediate data, and in the
general case you do need to increment the PC after the read (think about MOV
R0, @#0173000, opcode 010037,173000 which stores R0 in 173000).

Yeah, but could such a thing be done on Linux/UNIX OS's? I'm guessing that
you would need a NT server... and I don't like NT servers. I actually had a
NT and Linux server running on the exact same machine, at different times.
NT was harder to handle, and had more crashes just when I needed it most,
with many requests. Also, I had to reboot it 8 times to get it set up with
my video card, but not other cards, altogether, it took 16 reboots, compared
to 1 with Linux. My NT 5.0 beta is showing some signs of hope, but I'll
need a lot more before trusting NT with a hobby list as important as this
one.

probably they don't use VMS ... ;-))
but serious, i think they expanding this Hobbiist thing to other countries.

Wait a second, ARE there private newsgroups on this topic? I thought
it was just an idea everyone proposed but never did...

You can run the INN server under linux (or other UNIXes), and it supports
authorisation. I'd expect that the real problem is finding the extra space to
store the newsgroup files. At present, I don't think the list takes up much
file space, since the postings aren't archived (AFAIK).

Thanks! I also see that it only covers a few countries -- not including the
UK, where I am. I let my UK DECUS membership lapse, when they started charging
considerable (at least, from a student's point of view) amounts of money for
annual membership and vast amounts of money for software from the library.
It's not like in the States, where there's a no-charge Basic Membership. What
does DECUS do in other countries? There must be lots of peopel like us who
keep old 11s and VAXen running.

Well, since I wasn't the one who implemented the news server, I'm only
guessing as to its implementation. You can probably hang a NNTP (news)
server off of any Internet-accessible server. The news server has its own IP
address. Bill Whitson could create one off of the ClassicCmp server at
UofWA, or anyone else here with a free IP address and the approval of the
bosses. You could then also provide an e-mail gateway the news server so
that those who want the newsgroup activity by e-mail can get it.
Authentication is either anonymous or login required. Each of us is
given a login name and password (like rcini and 12345678), which will be
required to logon. From there, your newsreader takes over.
