Zetaco SCSI Controller

2019-12-17 Thread Sean Kelly via cctalk
Hi,

Would anyone happen to have or know the whereabouts of a technical manual 
and/or schematics for a Zetaco SCZ-2 controller?

Or the same for any other Zetaco SCZ (hoping that they all used the same 
back-plane presentation :) )

Many thanks

Seeking information on the CSTS Timesharing service

Jerry Reich has brought to my attention the operating systems written by
Computer Science Corporation (CSC) for its Infonet time-sharing network.
In the late 1960s, CSC developed CSCX, which was a highly modified EXEC II [*]
with time-sharing and multiprogramming capabilities. CSCX later evolved
into the CSTS time-sharing system used on the Infonet 1100s throughout
the 1970s. Commercial time-sharing networks were widespread during the
1960s and 1970s.


[*]
https://en.wikipedia.org/wiki/UNIVAC_EXEC_II
--
EXEC II is a discontinued operating system developed for the UNIVAC 1107
by Computer Sciences Corporation (CSC) while under contract to UNIVAC
to develop the machine's COBOL compiler. They developed EXEC II because
Univac's EXEC I operating system development was late. . .

EXEC II is a batch processing operating system that supports a
single job stream with concurrent spooling.



I have reason to believe that my very first exposure to digital
computers (in the spring of 1969, at a high school in northern
Delaware taking advantage of a Federal grant to equip a room
with some teletype machines and acoustic couplers) was to
"Conversational Fortran V" running on a Univac 1108 at Computer
Sciences Corporation. Presumably the operating system was CSC's
own modified version of Exec II (CSCX) rather than Exec 8,
but I believe the Fortran V language processor would have been the
same in either case. That taste of high-end timesharing was a
luxurious experience, never to be repeated -- the following year,
those same teletype machines were connected to an overloaded
IBM 1130 at the University of Delaware running BASIC.

For you Fortran folks, I need to explain Fortran V.

Based on Fortran IV, Fortran V was implemented on Univac 1100-series
hardware (and probably other Univac systems such as the 494) by
Computer Sciences Corporation in the late 1960s. It extended Fortran
to include parameter statements—basically a way to define constants,
conditional compilation, and statement functions—basically macros
that produced in-line code.

In 1970, I went to work for Computer Sciences Corporation working
on systems testing of a new timesharing system they were developing
called CSTS. While some of my work was done in assembly language,
the majority was done in Fortran V. For me, it was the "best scripting language"
I had available. (It was also the only language I had available on CSTS
itself for a while.)

I don't believe there should be any contact to make any "wear" affect 
the head.  It may have been damaged if you're talking one of the heads 
you cleaned up.  But heads should never really contact the drive on 
these types of heads.


I haven't posted earlier, but I had the same head technology on 
Microdata and Western Dynex drives.  Those had spring steel welded from 
the frame that attaches the positioner and the wires run out to the head 
via that arm.


The thing I had happen was that in fiddling with the head, and cleaning 
it, one could flex the head mounting.  It was a very stiff probably 
stainless steel, but I suspect in cleaning efforts early on when I was 
working with the heads and drives I got hold of some which either I or 
someone prior had over flexed.  The clearance is so small that I think 
that tweek allows the head to look okay, but in actuality isn't flown in 
the proper orientation to stay clear of the media.


I built a number of drives up from highly abused parts, and there were a 
lot of them, so got to play back then and learn.  Huge numbers of media, 
junk drives and the like.


Once I got new heads the problems vanished.  Never did get a reliable 
way to ID a head as good, so I always had a non essential removable 
platter I'd fit the heads to and fly them to see if they caused damage.  
If not, I'd move them to the fixed disk on the bottom of the positioner, 
and mount two more on the top that I'd vetted.  That saved the most 
media and heads.


But unfortunately not good now days where media and heads are scarce, 
since it risks the media and heads.

Re: Tap, tap, tap, is this working???

2019-12-17 Thread Fred Cisin via cctalk
I wonder of all the subscriber how many have posted something or 
anything in the last 6 month, year, ever?  I suspect the never cases.


Well, it is likely that if there is a subscriber harvesting, that that one 
is not posting.  But there are so many that don't post that you need a way 
to narrow it down further.  Automagically kicking out everybody who 
doesn't post doesn't seem like an appropriate action.


When I Google a topic, I often get hits that are posts on this list.  So, 
it is obviously possible to get posts from this list without subscribing.

(Sometimes I get my own previous posts on the topic)


I have always assumed that harvesting produced a list of addresses, 
probably a lot of smaller lists.


For one type of spam, that with a forged FROM from a friend or associate, 
that an address is chosen, possibly randomly, possibly by other criteria 
such as frequency of posting, and used for the FROM, and another for the 
TO.


Multiple smaller lists means that there is a high probability that the TO 
will recognize the FROM since they obviously have some contacts in 
common (well, at least the source of the list) and therefore the message 
is likely to get through.


I find it amusing that on many/most lists, when it is known that there is 
such actions going on, people bombard the FROM with advice that THAT 
computer has been compromised and taken over to send spam, should 
immediately change passwords, etc. and refuse to believe that the FROM 
line of the spam has nothing to do with where it is coming from.  People 
just won't accept that the FROM of an email is NOT necessarily the actual 
source of the email.  If you print "1600 Pennsylvania Avenue" on the upper 
left of snail-mail envelopes, would they insist that somebody has hijacked 
the whitehouse mail-room?



I find that SOME spam lists last forever.  I still get quite a bit of spam 
for an address that I created temporarily for Comdex 2000.

Short term solution is use Gmail then run for a while and then kill it

A partial "solution" for those who can handle multiple email addresses, 
snd can run a "white-list" filter, would be to create an address that is 
ONLY for posts to and from this list.  THEN, any mails that come to that 
address get filtered to only pass those that purport to come from this 
list.  All others being put in a special "probably spam" folder.  Glance 
at that folder periodicaally to retrieve any that are actually private 
messages sent by somebody on the list.  Discarding that dedicated address 
periodically will lose few valid correspondents.


That would be a valid use for a "white-list" filter.

Other than that, I don't normally find "white-list" useful, because a 
significant part of the email that I get, such as about XenoCopy, is from 
people I have never encountered before.  It would be insane suicide for a 
business to only accept contact from their prior contacts!
Similarly, after my mother died, I got phone calls and emails from 
relatives I had never met.




At one time Google used to publish recommendations to avoid having emails
inadvertently stopped by their antispam systems.  At that time, I made sure
that my mail server complied with all their recommendations.


As did all spammers, so Google probably found it counter-productive to 
discuss their algorithms, and didn't know WHICH parts of their algorithms 
should be published V kept secret.


I've since tried to contact Google to ask them about this but I've had 
no success.


It probably went into the Google Tech Support department's spam folder. 
:-)



Since this address is on PINE, I often forward emails that I want to look 
at, but that need a "modern" client (such as attachments, pictures, etc.) 
to my gmail address.  A lot of those get sent to the spam folder of my 
gmail address.  Marking them as "not spam", etc. hasn't helped to convince 
gmail that I don't consider anything from THIS other address of mine to be 
spam.  So, they don't seem to have a white-list over-ride.


I have to have that "modern" account for otherwise unreadable emails.
A friend coming into town emailed me her Orbitz itinerary.  Full of lots 
of ads and "of interest", and with pictures of text rather than text.

The easy way is subscribe and copy the mail and scrape the addresses.

Compromised machines makes the list activity visible as well.

In my experience with 2315 packs, the top heads are the most prone to crashing.

What is bizarre is that one email address that posts to the list is getting
lots of spam and another email address that also posts to the list is not.

What is also bizarre is that your spam stops when you unsubscribe from the
list (if that is what you mean by "stopping this net" and "bailed from the

they don't bother to check whether the address is still active any time

I think you are jumping to conclusions here.  In my experience, spammers
are very lazy people and they are just not willing to put in that sort of
effort.  Unless the spams you are getting are very specifically designed
for you, I would discount this theory.

I'm a mere blow in that hasn't been here more than 25 years.  I worked for
an email provider for 15 years and for the first 5 years of that, email
spam didn't really exist (unless you count the "call for papers" type of
academic spam).  After that, I put a lot of work into understanding spam
and preventing it from getting to or from our customers.

It is really really difficult to come up with a useful filtering system that
can recognise and stop spam without stopping good mail too.  The only ones
I use are DNS based lists of ip addresses which are known sources of spam,
such as those operated by Spamhaus.  I also use my own homegrown ip lists.
This approach works for me because I have my own mail server.  If you are
stuck with using a commercial email provider, you are stuck with what they
are using.  Many commercial providers won't even reveal what they are using.
As for the free email providers, forget it.

The ip address based filtering I use stopped just one spam going to my
cctalk mailbox since April 2019 (there was a spate of it in April).  Filtering
is never a complete solution.  The best way to avoid spam is to avoid having
email addresses harvested but this is not always possible when people we
correspond with unwittingly get their machines compromised.

Another thing I believe makes a difference is to complain about every single
spam received to the ip provider of the spammer or the compromised machine
used to send the spam.  Nobody else I know is willing to put the effort into
doing this though.  However, nobody else I know has as good a legitimate mail
to spam mail ratio as I do either.  (Obviously this approach can not help
when already getting too much spam to cope with.)

Speaking of RPG.... was :Re: Is IBM RPG classic?

Hi all,

This discussion brought up some memories. Until I retired, I was in the 
media conversion business (read : handling media Windows did not 
support). One of my customers was the danish Custom and Tax authority, 
and they had a peculiar problem. They wanted the incoming data to be 
verified before the data was forwarded to the mainframe, so they did not 
have to search through boxes of media when errors were found, in order 
to be able to return the medium to the supplier.


The software used for the conversion, was called 'Intermedia for 
Windows'. Apart from being able to do normal conversions, there was the 
possibility to lead the data through a customer-defined DLL, before 
being written to the ouputfile.


So what I had to do, was to develop a Windows DLL, doing whatever was 
specified by the customer, including writing errorlists, table look-ups 
and other niceties. And as the customer had RPG-II experience in-house, 
the job was clearly defined.


This was accomplished by writing an RPG-II editor, written in Delphi. A 
program would then interprete the RPG-II source, and would then compile 
it into a DLL.


Surprisingly, it worked quite well

Thanks for all the replies, both humorous and informative.  I'll try to
find out what version of RPG my friend has the misfortune to be working
with, and what platform it's on.
