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.

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.

I had looked in jameco's catalog before, and the prices seem rather high! $25
for a single mathco is outrageous. i remember they did/do sell system boards
that arent necessarily state of the art for 2-3 times a "normal" price. do
they still sell apple parts? mouser electronics (if still around) might have
parts cheaper.

The EXACT place to look is Jameco, at http://www.jameco.com . In their

Sorry, the big DB that doesn't go anywhere is used to add another MFM
hard disk. It contains the control and data signals for the second drive.
I've not seen the 8-port option, but I believe it plugs in place of the
color graphics board.

Gerhard Moeller (I believe that's his name) has hacked over the SCSI driver
for the MicroVAX 3100 to bring it up on the 2000. I've used the driver under
VMS 7.1 to speak to a tape drive (this gives me a nice little package to take on
travel; a 2000 with an RD32 and a TZ30). Since it's a full-up SCSI port driver,
it can be used to support anything VMS knows how to talk to; disks, tapes,
etc. I've heard of one fellow who is using a 2000 to burn CDs.
I suggest looking around on dejanews for discussion of Moeller's driver.

All 2000s include a monochrome display built into the motherboard. It is also
possible to add on a color display. Rumor has it that it is not impossible
to use both displays simultaneously, but I've never tried it (my color
monitors have died over the years).

Nephew has acquired a Telex 181-GP dot matrix printer. I've looked on the
net, and it looks like Telex is all but gone. Any idea where I might find
documentation on this unit? I'm assuming it emulates a 5152, like almost
every other DM made in the 80's.
Kind of ironic, as we had a huge Telex facility here in Tulsa for years.

I recently acquired a Morrow Designs Pivot Model 2522 - Special,
serial number 31-0001488. Both the model number and serial number are
hand written on the manufacturer plate on the rear of this pc. It has
dual 5 1/4 " floppy drives and 640k memory. The memory board is
labelled Morrow Zenith.This is an interesting portable having a rom
monitor for the built-in modem, what appears to be a built-in
calculator (haven't been able to get the calculator button to do
anything). Date can be changed in the monitor by pressing a button
also. Boots MS-DOS fine.
I read in Stan Veit's book that Zenith licensed this technology from
Morrow. Does anyone have any further info on this unit or better yet a
operation manual?
Thanks-

Today I bought three portable PCs marked "Rabbit 286". They're about
the size of a large lunch box and have a keyboard that fastens against one
side. When you remove the keyboard it uncovers a gas plasma screen. There
are slots for two 3.5 drives on the right hand side and a door on the left
side. Opening the door exposes the back of several expansion card slots.
There's a label on the bottom that says "Chicony Electronics Co.", "Model
286G-A", "Gas Plasma Display" and "640H x 400W Dots". One almost works, one
is dead and the third one is somewhere in between. Does anyone know
anything about these? I'm wondering if it's possible to put a small 386 or
486 mother board in these.

That's exactly where I got it from. Now, I was just thinking that in 1973,
that would be a huge space, the size (or larger) than hard drives! So you
could transmit your entire hard drive in a second, barring server stuff and
hard drive speed. It sounded strange to me. ;-)

Well after the 2901! it's far more complex. It was preceded by the 8x300
and the 3x305 was somthing like 1979-81.

My point too. There's a big difference in "market value" and "collector
value". (Don't believe me, buy a "collectible" plate sometime, or coins
>from a TV shopping channel.) Market value is what the average idiot will
pay, at auction or elsewhere. Collector value is what an informed

I've got books on disney, hot wheels/corgi/dinky/matchbox/etc., glassware,
collectible board games, and so on (used to be in the business, kinda) and
I am often amazed at what things sell for, at auction, at antique shows, in
stores, as well as at garage sales, flea markets, and so on. Heck, Hake's
is one of the biggest value setters in the US of pricing on Disney,
politicals, advertising, and so on stuff, but still, a lot of collectors
(me included) think their prices are inflated. Market value versus
collector value.

Ah, but... Say I'm a newbie to the group (and don't take this
personally!), how do I know that if I sell you my //c LCD screen for $20, I
won't see it listed on eBay next week with a starting bid of $400?
And even though I know you wouldn't do that, I still not that easy. As an
example, I've got two SE/30 motherboards, brand new, in the Apple Service
boxes. I know some people here expressed interest in them, so I should
probably offer them here, cheaply. The problem is, they're actually part
of the Mac stuff allocated to my girlfriend's school. If I sold them on
eBay, I might get enough to buy a complete, working IIci system to put into
the classroom for the kids to use. What do I do?
And even if they weren't going to the school, I wasn't able to take my dad
and niece to Disneyland this year because I can't afford it. If I sold
them on eBay, that would pay for part of a cheap trip to Dland.
Like I said, tough call.

Here's an idea...
How about making Friday the "classifieds section" day? You know, like
the local newspaper. Although classifieds appear in newspspers daily, it
seems that one day has many more than the others.
This would reduce the daily FS/T traffic, but still enable people to
trade stuff. I see ClassicCmp as a great resource, not only for information
not available elsewhere, but also for physical equipment and software which
is obviously no longer made or supported by the manufacturer.
I also think that those on this list should give (and be given) first
crack at something that one of us has for sale. We all know eachother, have
dealth with eachother previously, and for the most part, know that "the
check is good."
Trading should continue, but maybe it should be aggregated and done on
one day. Maybe Monday's the right day...maybe Friday. I don't know.
Just my $0.02.
Happy Holidays to all.

It has. It comes up every now and then on every mailing list. What
usually happens is that those who want a newsgroup go off a create a
newsgroup, and the ones who can't access or don't like newsgroups stick to
the e-mail list, and the real die-hards follow both, cross-posting stuff

That's right 'ls181, a crude bit slice ALU. I remember there was a way
to download microcode directly, the RSX driver supported it. None of
those cool 2900 series slices were around yet, maybe even the 8x305 was
still on the drawing board. I still have the AMD 2901 design book,
heavy going but it tells you everything you ever want to know about
building a CPU from scratch. I don't suppose anyone has some kind of
system built from 2901 bit slices? Roll your own microcoded instruction
sets?
