What timing *sigh*
I just noticed this morning that there is a rather severe problem with both our primary and secondary mail servers for the classiccmp.org domain. I must admit with much chagrin that it appears to be one of a set of changes that I made a week or two ago, but only manifested itself this morning. I am not sure of exactly which change caused the problem, but I have been working on it all day and will continue to do so till the problem is fixed.
Symptoms - inbound connections from remote mail servers experience a long delay after the connection is made before sendmail acknowledges the connection. Most of the time the mail goes through, but the long pause bothers me. Other times the remote mail server times out, and retries later, but gets through. As a result, it appears that mail is going through but is significantly delayed. The error message is the typical "timeout waiting for..... during client greeting". No, the problem is definitely not reverse DNS (ident) or low level network related - the typical causes for that problem.
I will post to the list once the problem is resolved, unless I choose to finally get some sleep.

I have used ExpressPCB and the free layout software on two projects. The
layout software is for Windows and does double sided boards only. This
software emails the design to ExpressPCB so it is not general purpose.
If a two layer board will meet your needs I recommend ExpressPCB. Their
service is fast and the software is easy to use.
http://www.expresspcb.com
Two 10 by 10 boards with no solder mask are +ACQ-230 (+ACQ-70 setup, +ACQ-80 per board)
with a 3 day delivery.
Two 10 by 10 boards with silk screen and solder mask are +ACQ-370 (+ACQ-310 setup,
+ACQ-27 per board) with a 10 day delivery
Boards up to 5.25 by 4 with silk screen and solder mask are +ACQ-229 for 5
boards.
The company also offers a full featured PCB board production service. Your
boards are actually manufactured here.
http://www.pcbexpress.com/
I have access to commercial grade design software (PADS PowerPCB) but it is
very difficult to get up to speed on the full featured software if you are
doing one design a year. If you mess up on producing your output files your
boards are junk. It is difficult to make operator errors in the ExpressPCB
software. (You can still route the trace to the wrong pin.)
You can see my projects here:

I've used ExpressPCB...just last week, as a matter of fact. Their
boards are quite decent, and their service is fast and predictable.

The trouble ALWAYS starts when someone posts an

or an answer. It's not news or information. It's not
a recollection and it's not history. It's not on topic.
Opinions are unavoidable, but self control (and
counting to 50,000) can really cut down on the
noise.

Actually not less than 4 different versions as LK201 and then you

This is doable. Though most of the LK201s had 8051 chips and you
could program a 8751 and put that in if you like.

Hi,
I have a PDP-11/34 programmer's console but no PDP-11/34, what
should I do with it? My options are:
1) get a PDP-11/34
2) trade it with something I need more, like a PDP-8/A power
regulator(G8018) and limited function panel so that I can
build my third PDP-8/A :-)
PDP-11s were never really my plan to collect, but I wouldn't
mind having one specimen of 2.9 BSD running. So, may be I
should get an 11/34?
cheers,
-Gunther

Help - What am I doing wrong?
I sent the following response (SEE AFTER DOUBLE LINES of ======)
to a previous e-mail in respect of auction:
http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=2006598832
This time he did not even reply. Am I being overly cautious is making
sure that the correct customs documents are used?
Previously, we have agreed on the Shipping, Handling and insurance
to be $ 24.45 and that he would ship to Canada, but for some reason
which I can't understand, he seems to think that using the GREEN CN-22
or a COMMERCIAL INVOICE is not a reasonable requirement.
While the shipping seems a bit high, I did not quibble and agreed to
pay what was asked.
His Positive feedback seems satisfactory, so what could the problem be?
His name and address are:
Bobert1959(a)aol.com
Bob Bruns
6334 Alta Oaks Dr
Garland, TX 75043
However, this information seems to not be traceable.
Is there anyone at eBay whom I can contact?
Any other suggestions?
Sincerely yours,
Jerome Fine
MY RESPONSE TO HIS E-MAIL FOLLOWS:
Bob Burns does not reply.
================================================
================================================
>Bobert1959(a)aol.com wrote:

Jerome Fine replies:
If everything in this e-mail is satisfactory, please respond with
"Confirmed" as the first word in the body of your reply.
Also, please add if you wish me to prepare the COMMERCIAL
INVOICE for you.
Your reply seems to suggest that by requesting that you comply with
shipping requirements at port of entry into Canada (and probably
any country - although I am not familiar with regulations elsewhere),
I am changing the terms of the auction. I hope that this reply will
help you to understand that the terms of the auction are not
part of the requirements for shipping the drive and that I have
nothing to do with these requirements.
In addition, if you read my last e-mail carefully, all that you have
been asked to do is to correctly provide the value of the item
to the customs officials in Canada. When a package is sent via
USPS, then I understand that a GREEN CN-22 form is used.
However, since I am not aware of exactly how USPS handles
air shipments, I may be incorrect. In that case, customs officials
in Canada may require a "Commercial Invoice" which is filled
out (based on my limited understanding) as a simple paper with:
===================================
COMMERCIAL INVOICE
Your Name, Address and phone contact number
My Name, Address and phone contact number
Value of the Drive: $ US 11.50
===================================
It is that simple. I don't set the requirements.
Here is my part if you need to send a Commercial Invoice:
Fine Services & Co. Ltd.
PST Exempt - 1531 2240
2 Inglis Gate
Willowdale, Ontario, Canada M2R 3G3
Attention: Jerome Fine (416) 667-8233
Please note that ALL FIVE lines are essential
for the complete address and contact phone number.
In addition, ALL FIVE lines are essential on the
outside of the box and on any shipping document.
I will include this information on a sheet of paper
which I will include with the money order and the
auction Item Number 2006598832. All you
will need to do if a Commercial Invoice is required
is to add your contact phone number to your
name and address plus the actual value of the
eBay auction.
Again, I don't set the shipping arrangements - they
are imposed by Canadian Customs at the port of
entry. I you wish, I can prepare the COMMERCIAL
INVOICE for you - all you will need to do is add your
contact phone number to the paper.
I anticipate that you don't wish to violate the requirements
that Customs Canada imposes. I certainly don't think
that a COMMERCIAL INVOICE is a difficult requirement
since it takes less than a minute to fill out. All of our e-mails
have certainly taken much longer. Certainly I have never
encountered anyone who has ever refused to provide
a COMMERCIAL INVOICE to Canadian Customs
since all of the information is normally available in any
case, just not consolidated onto the form which they
insist on - although I agree it is a pain in the posterior
if you ask my opinion.
Sincerely yours,
Jerome Fine

Another vote of thanks & support for Jay; the solution
to the essential problem of wasted bandwidth lies with
the rest of us and not him.
And Sellam, if you can't refrain from needlessly adding

Is this the manual for the thermal AppleScribe printer? (sounds like it)
If it is, can you toss it in the mail for me? Priority is fine with me
(so you can get a free envelope or box, or whatever... it isn't a fragile
item so a simple priority mail pouch will work well).
I can mail you cash, or stamps, or send paypal, or whatever you want to
cover postage.

I, too, appreciate the work Jay has done on the list. I use this list as an
example of a large well managed community. Even though there has been a
slight increase of Spam recently it is way, way, way below any other list. We
generate more Spam about the Spam than the originators.
I am not in favor of closing the list just like I am not in favor of closing
the community. Some times moderation is necessary but in IMHO less is best. I
believe in self moderation, something we seem to be falling down on lately.
If we do not reply to or about the Spam it will be hardly noticeable. And
here I am adding to it.
I would rather learn about how to attack Spam at it's source. I am learning
how to decipher the mail headers. I need to figure out how to automate
complaint letters. From what I have seen the direct complaint to the service
provider works best.
Links to any tutorials would be appreciated, as would recommendations on SW.

PS From what I have seen most of the Spam the list has gotten is very
international in it's source and not traceable back to a single source.
The FBI would like copies of the Nigerian Scam emails. They are starting to
take it more seriously.

I feel the need to chime in with some support for Jay. This is a
high-traffic list with a lot of recipients, which surely takes a
nontrivial amount of bandwidth and system resources to host...people
shouldn't lose sight of that fact. I run a couple of fairly large
mailing lists myself; something like this isn't a "set it and forget
it" thing...Spam is the least of the problems, most of the time.
People with crappy network connections whose mail gets backed up and
queued, Windows programs that screw up everything in sight when moving
mail around, twenty-line messages turning into 50Kbytes due to rampant
Microsoft HTMLization bogging down the mail server, etc etc etc. It's
a pain in the ass, and it takes a certain amount of babysitting to
keep things running smoothly.
Jay does a fine job. He may not have started this list, but he runs
it now...and that counts for a lot.
I hate spam as much as anyone. Actually, I hate spam a lot MORE than
most for various reasons. But guess what...My mailer has a "delete"
function, and I actually know how to use it! Wow, what a concept.
I know, I know..."but spam slows down my net connection!" If your net
connection sucks so badly that a little (or a lot) of spam bogs it
down, then get something faster. There's no real excuse in this day
and age. Spam blows dog, there's no question about it...but it's a
fact of life on the internet today. Everyone should fight it whenever
and wherever they can, but you WILL get spam if you have an email
address. The sooner people learn to deal with that, the happier
everyone will be.
Further...there are lots of off-topic conversations on this mailing
list. I take part in many of them, so I'm as guilty as anyone. But
you know what? Humans are social animals, and this list is a social
thing. Many of you are my friends. If there's an off-topic
discussion here that you don't want to take part in, well, use that
magical "delete" key...Every mailer has one.
In other words...if anyone here has a life that's so utterly perfect
that spam and off-topic discussions can offset the friendship,
comeradery, education, and other classiccmp benefits, I'll swap lives
with you any day of the week.
Sheesh.

I say OT because some of this applies to newer machines, but I
thought it might me worth sharing.
I was in a tinkering mood yesterday. I had recently pulled the 256 mb
(three dinky DIMMS) from a Pentium II and put in two 256 mb sticks.
My motherboard docs state a max of 512 mb, but now I got a spare memory
socket and could not resist. I stuck another 32 mb in and fired it up.
The BIOS self test ran OK, and it booted to DOS find. But when I brought
Microslop Windoze 95, I learned the true meaning of Windoze. You could
click on the start button, take a drink of coffee, light up a smoke, and
maybe, just maybe, the start menu would appear by the time you did that.
A whole new meaning to the word slow.
Needless to say, I pulled the 32 mb. Windoze returned to its 'normal'
speed.
Not content to stop there, I decided to up the size of the ramdisk from
16 mb to 32 mb. Since I boot to the DOS prompt, it was easy to catch the
error stating invalid ramdisk parameter. So I took it back to 16 mb and
starting incrementing it. I got all the way to 30 mb with no problems,
or so I thought. I had only booted to DOS, and not brought up Win95
during the time. With a 30 mb ramdisk I brought it up. My display settings
were changed and the display adapter was complaining. I returned the
ramdisk to 16 mb and all returned to normal.
I found nothing on a specific limit on a ramdisk in any docs I looked
at. I have used a ramdisk since my XT days. Now it is almost like they
don't want us to know about it.
Any thoughts?
----------------------------------------
I also have been trying to add some memory to an old Gateway 486/33 machine
I use for utility things. It already has 16 mb. I've tried several
combinations of SIMMS all meeting GW requirements (36 bit parity 70 ns).
It comes down to no matter what combination I put in, nor how I set the
memory dip switches, it won't recognize anything beyond 16 mb. I have
the manual of this beast, and it clearly states it is expandable to 64 mb.
----------------------------------------
And finally, I was confused by the recent posting on the DEC 3000/300.
The reason was that someone handed me a bag of DEC SIMMS some time back
and I thought they were for a 3000 but the descriptions in the recent
posting dod not jive with what I had. The ones I have are 100 pin,
10 chip, 70ns and are a 4 mb module with room for another 4 mb on the
back. It would seem that mine are for the 3000/400 and maybe higher.
Mike
I have just been given a Display Writer system complete with CPU,
Keyboard, Monitor, Dual 8" floppy drive and some floppy disks. I have been
told it works but I haven't tested it myself yet. It is surplus to my
requirements so if anybody wants it they can have it. I can test it if
there is interest.
