I never heard of a 709T but if I remember right, there was a 709 (but
it was before my time). As a general rule, machines with three-digit
numbers were vacuum tube machines, and those with four-digit numbers
had transistors instead of tubes.
I think this is right, and the addition of the T was to indicate that
this 709 had transistors, not vacuum tubes. Then, if my memory is not
too foggy, the pronunciation 709T morphed into 7090, and to eliminate
the confusion the T suffix was dropped. Gordon

Could be, I suppose, but as I said, although I was active in the
mainframe world around that time, I never heard of it.

I have a copy of a big 1986 book entitled "IBM's Early Computers,"
which I've hardly looked at before. I just browsed through it, looking
for info on a 709T. Here's the scoop. There apparently was never a
709T, but before the 7090 was released, while it was still under
development, they called it the "709TX."

I said that I had never heard of a 709T. I had never heard of a 709TX
either. <g>

On the 7080? I mostly programmed in COBOL, but patched in machine
language.

But most of my early programming was on the 1401, in SPS and Autocoder
(both assembly languages), also doing patching in machine language.

In 1968, I moved to 360s, again doing mostly COBOL, with a little bit
of assembler.

Over the years, I've worked on a variety of different machines, using
a variety of different languages, including the assembler SALT, on a
Univac II. And back in the late 1980s. I did a little PC assembler.

Sorry ass troll, they should have strangled your sorry nym shifting ass
with your own placenta at birth and tossed you in the dumpster.

Is this your best troll-a-rama ? You are what you are/

Spit in your face and swing upside your head with a brick you sick
bastard. :)

Hi, Gordon - and XS11E.

Class of '52! Me, too! And I'm a lot older than Ken:

I know, I know. <g>

For the others here, RC and I have met several times, which is why we
both know how old the other is.

I'll turn 76 tomorrow. ;<)

But I didn't know that. And since I'm replying "tomorrow," have a very
happy birthday!

I can still read the Hollerith code...

Me too--at least numbers and letters, which are very easy and hard to
forget. The special characters, which are triple punches, I've
completely forgotten.

... but I haven't seen a punched card in years.

I still own a t-shirt with an image of a punched card across my chest.
It has my name "punched" into it.

For years after I stopped using punched cards, I had a bunch of blank
cards that I used as bookmarks. I think those are all worn out and
gone now, but I wouldn't be surprised if I came across a book I
haven't looked at in years that still has one stuck in it.

And somewhere around here, I think I still have a small deck of cards
with a COBOL routine I wanted to save. I don't know where it is
though, and it's possible I threw it out.

Don't miss 'em.

Nor I.

For my wasted years toiling for the Itty Bitty Machine Company I used to keep some blank card in my white shirt pocket, right
next to my 'sincere' tie* for note keeping.


*anyone know the source of that bit? Herb Caen, in one of his columns for the San Francisco Examiner mentioned IBM employees
with their white shirts and sincere ties..

http://en.wikipedia.org/wiki/Herb_Caen

BTW, IBM's allowing shirts other than white was a major economic blow to J. C. Penny's, always the best source of good but
inexpensive white dress shirts....

FWIW, I guess the years weren't totally wasted, I learned to work on stuff with oil, grease and ink while wearing a suit and
white shirt and the retirement check keeps coming...

There was never a 7060 either. In the 7xxx series, there was 7030
(the biggest computer, in its day, and there were very few of them
made--seven I think), 7040, 7044, 7070, 7074, 7080 (the only one of
the 7xxx series that I ever programmed on), 7090, and 7094.
For you young fellas, I have uploaded a 7-zip file of 1.6MB to
Mediafire and which I have called "IBM Mainframe History". The file
inside is a PDF file of 1.7MB of the same name.

The name on the cover of the 45-page book is "IBM Mainframes -
45 Years of Evolution"

It may jog a few memorys (pun intended).

I'm afraid my memory far exceeds MTBF.

A link would have been nice, but here is a link to a 46 page publication
of the same name from IBM. It is 2.14 MB.

IBM never had memory, they had storage. Only humans have memory.
