John,

64k is correct. I started working at a company in 1984 that was converting
from an IBM/360 to a HP Series 33. The 360 had 64K of memory 5 800 bpi tape
drives (the fancy ones with the vacuum feed), and 2 disk drives the size of
a washing machine holding a grand total of 7 meg of data. Must not forget
the printer 1100 lines a minute and the cover moved up and down
hydraulically.

I also worked on Sperry Univac OS so some times I am not sure of which JCL
is correct but I do remember it was something like:

//JOB
//VOL (volume (diskdrive) name here)
//LBL (name of file)
//LFD (program name of file)
//EXE
//EOJ

Here is a link to a picture (second one down) that looks very close to the
one I worked on. Our operator Marty did not look a nice as the one in the
picture.

I still have a COBOL program around that was written in 1974 on the 360,
converted to HP in 84 and ran in production till 2001 until the company
closed down. Since it was an accounting program it probably would be still
running today if the company existed.

This phrase just tickled my nostalgic funny bone as it set off memories of
my first job working for IBM when a Job card was just that.

I worked at the Hursley IBM site as a 19 year old (in 1969) who had never
seen a computer before. I was introduced to programming and had to use a
keypunch machine to set up a huge deck of cards of which the first card was
"the job card" and the next several were all JCL (Job Control Language)
cards. It makes me smile when I think of the huge room containing a 360/64
computer which consisted of several large refrigerator size cabinets, all to
house 64k of memory (if I remember correctly -- or was it 64 meg?).
Debugging the computer was done by pressing a switch on the front panel to
single step through the program and a "techie" would write down the numbers
based on the lights displayed to determine what instructions were executing.
:o) It now seems incredible that writing programs required a huge deck of
cards to be punched with a single line on each card (Hollerith springs to
mind !). The tray of cards would be submitted to the operators for overnight
processing and the next day a print out would show you where a punctuation
error had occurred, for example which meant going through the cards, finding
the offending one and replacing it with a corrected one. Then the whole deck
would be resubmitted for overnight processing again. This pattern would be
repeated until the program worked. Heaven help any operator who dropped a
tray of cards and they got all mixed up!

This experience even pre-dated my visit to college where programs were
submitted using paper tape to an ICL 1701 machine.  Paper tape also had
nightmare qualities of its own. It seemed that it was always just as you got
close to the end of a complicated program that the tape would break and you
would have to start again. However, it was a slight improvement on the
cards.

Just thought I would share that with you. I expect others have similar
nostalgic stories.
I for one would enjoy hearing them.  Perhaps Ron Seybold could have a
nostalgia corner somewhere.  :o)

Cheers,

John Dunlop
