Bob asks about row/column based database software.
+ADw-snip+AD4-
Lots of mainframe database software existed but it was expensive and
took lots of CPU power and disk space. From my experience it all
depended if you purchased software or wrote your own.
At the University of Missouri in 1976 we made a database of food
poisoning victims.
I used one punch card for each patient which was one row.
Each column on the card was for each symptom or food consumed.
Columns 1-16 was usually last name
Column 17 might be Saturday morning vomiting
Column 18 might be Saturday afternoon vomiting
Column 19 might be Saturday evening vomiting
Column 20 might be Saturday morning diarrhea
Column 21 might be Saturday afternoon diarrhea
Column 22 might be Saturday evening diarrhea
Column 23 might be Saturday morning beer
Column 24 might be Saturday afternoon beer
Column 25 might be Saturday evening beer
We would usually look at a 3 day interval.
It usually takes 18 hours for food poisoning symptoms to start.
Some people are +ACI-immune/tough+ACI- and don't get sick.
Some people have symptoms from other sources+ADs- beer, other foods
If you listed a data deck of cards then row columns were how the data
was listed. We looked to trends and correlations. On one outbreak the
highest correlation was the potato chips but the chicken salad was the
actual cause. We used to get a lot of false positives for vomiting due
to the amount of beer consumed by students.
We also used SPSS on IBM 370/168 to analyze data also printed 2 X 2
tables of cross-correlations. The data was punched on an IBM 026 card
punch, later we got a 029.
We moved the analysis into FORTRAN programs on PDP-11/20 using DOS.
Later in 1979 I used BMDP and Datatrieve on a PDP-11/35 to computer
percentages of bacteria that consumed certain sugars.
The table looked like
S L M C
U A A A
C C N S
R T I I
O O T N
S S O E
E E L
e.coli 75 5 5 10
s.aureus 5 1 1 95
P.aeruginose 10 50 50 1
The PDP-11/35 was later upgraded to a PDP-11/70. BMDP required overlays
and lots of common areas to fit in the limited memory we had. We had
320K words of memory for 6 users, the RSX-11M OS and all external device
pages. All of our data was on RK05's. The system was on one RK05, the
programs on another, one for scratch and another for data. We changed
the data packs a lot to load more data. Our first RP04 was setup by us
to look like lots of RK05's since we stored data and analyzed in those
increments. For the clinical machines the data was stored in a PROM
board on a PDP-11/04 that analyzed bacterial growth and identified the
bacteria. If I remember correctly the table was about 30 rows by 26
columns.
Minicomputers were an attempt to move out of the computer center. We
weren't really classed as computer programmers but R+ACY-D engineers. We
stored lots of data in RAD50 and bit flags to save space.

Trim replies and change subject when appropriate.
I'm guilty of failing to do both at times but I'll
try to do better.

thanks and kudoos to Dwight and Dave for lightening a stressful day at work. To have taken my rather terse comment and created such wonderful content is what life is all about. LOL
best regards, Steve
now my only problem is whether I should leave the rest of the email or snip it off... sigh

I believe that Steves Last Comment (that being the last comment that I
received before any comments that he may have sent that I don't believe you
to have read at the time you sent the message that I am responding to and
you will soon (hopefully) be reading).
It would be a personal insult to Steve to NOT believe that he was sincere an
honest in that comment. Although the one prior to it (in the same message),
which has previously generated feedback from me (oh should I include that
too) may be taken in a number of ways, as I have previously done.
Additionally the interveneing comments by other members have an impact also
(although I am not sure what it is), but if you mook solely at the messages
that were sent in the interval between Patricks first post on this subject
and Hans first response you will see that Dave Dunfield has been tring to
focus on his own issue (which Wayne has of course been helping on).
I do suspect that Wayne may hve just been lurking since himing in in on the
other issue, which I wonder if the original poster ever got an answer that
he can use for hist original purpose..It would be interesting if the 94
responses (subjed to the one by Wayne mentioned above) did not provide such
an answer.
Or is it really not suprising since that is difficult to determine using
this technology....
David.

Hi Steve
You make several good points but I find your last
statement without foundation.
I tend to agree.

You are correct, that is what the adaptor is for. Or at least it looks
just like the one I had for that purpose. I'm not sure if I still have
mine or not (I no longer have the Wyse PC it went with)
I have a crappy diagram and pinout to make one of these:

When I finally get to play with my TU81E, I'm sure I will find them
useful! My drive is known good, but still having manuals is very
valuable just in case. Please put them up for all of us!

Hi Wayne,
Where exactly in the maintenance manual are the codes listed - I did not
find them when I looked.
Although the machine was stored with a tape in the drive (keep mice out),
I had already removed it before my tests.--

Very impressive. Look like a F series in dual bay rack, lots and lots of
memory (HSFCA at that!), and a 7925 disc drive that looks to be mint.
My trailer would have no problem driving to the UK *GRIN*

My 5100 maintenance manual is buried, but my 5110 manual says that error
"07" is a CRC error in the ROS. I have notes diagnosing a similar
problem indicating that one possible solution is to remove any tape in
the tape drive before powering on. Seems unlikely that this would work,
but you never know.
