My Cup

I was just looking at my favorite cup. I estimate that I've had at least 15,000 cups of coffee out of it. It looks like new. I was looking at the MS/DOS commands and surprisingly they never left. It was given out by Microsoft as an inducement to use MS/DOS.
Maybe it's like riding a bike. You never forget. For those that don't remember, it was what they used before Windows. In some ways it was superior. You always got what you wanted.
But my time with computers goes back to the dark ages in 1953. When most of you were riding around in you old man's jock strap. Computers in those days were analog and not digital. Programs were written on IBM cards and read outs were on a Dumont Scope.
My first use of a computer was to look at the distributed stress on a cantilevered beam. It gave me loading for every inch on the beam. It took 2500 punched cards and half a day to run. The same equations can be done on a hand held TI-30 calculator.
So you can see the amazement I feel when look at Windows XP and FSX. However, when I look at Windows Vista I feel like we were back 55 years ago.
 
Wow! Programs written on IBM cards...my gosh! I'm intrigued now! I'll have to look it up on the internet to get a full understanding of the whole process.
The evolution of technology is always fascinating. Thanks for the glimpse back in techonology history Helldiver.

I enjoyed the cup picture as well :jump: It does look brand new!
 
There was no memory back then. They put the data on cards with punch outs, about the same thing. Back then programs were small compared to no.
You would need about a million cards to do a todays program.
 
Man we have come a long way...

From cards to cassettes, to floppy discs to disckettes, to CD's and then to DVD's, from HD's to Solid State HD's, from microchips to quad core chips and dual core graphics cards...

I am still trying to figure out how they put 16 GIGS! of memory in this iPod Touch. Its so small, has WiFi connection, has Google Earth, the Bible in about 30 languages and versions, 900 photos, several movies and programs, tons of music, and its only half full......

Thank the Lord for the tools of technology.

HD, didn't Dumont make TV's back in the 1950's? Our old set was a Philco but I seem to recall that Dumonts were advertised a lot back then. I remember when I was aboard ship in 1971, the A-6 squadron intel guys had an early HP or TI pocket calculator that did trig functions. They used it for offset aimpoint calculations. It cost the squadron $140 to purchase it retail. Seven years later I bought a TI-30 at Walgreens in San Diego for $20. :d
 
Dumont made TVs and also had the first commercial TV network

http://www.tvhistory.tv/1950-59-DUMONT.htm
The RA165 was the first TV in my house.

http://en.wikipedia.org/wiki/DuMont_Television_Network
WABI, the first TV station in Bangor carried a mix of what
was available from all 4 networks. I remember Bishop Sheen
and Captain Video.

My last contact with the IBM punch cards was as an ordering clerk
many years ago. I would use a big ledger style book to order and
then put that on a rack that held a deck of cards. I would transfer
the numbers from the book to the cards and mail the completed
deck to the warehouse where they would run them through the
computer to print out tear strips for the order pickers.

Today when 24 cans of Del Monte peas goes through any combination
of cash registers, a case is automatically added to the next delivery.
 
I started my college IT career with punched cards on the old IBM electronic accounting machines, programming boards, using sorters, collators, interpreters, and keypunch machines. These all used the IBM Punched card Hollerith 80 column format as shown here. Encoding used was EBCDIC (Extended Binary Coded Decimal Interchange Code). Basic cards were readable for data using standard hexidecimal interpretation, each column represented one byte. The binary card shown is from a compiled Fortran program and represents binary machine code.

In RW, I programmed an IBM 360 model 20 initially, a card based system. Of course they had memory but only 8K. In the mid-60's, a megabyte of memory cost $1 million, basically, $1 per byte. The memory at that time was made of "core", basic on/off switches, and a successor to the earlier vacuum tubes as used in TV's at the time.

Later, we added disk drives, 7.5MB each, and each drive was half the size of an office desk. The disks were made up of a stack of platters, about 9 or so in the stack, each side recordable. This disks were removable so you could use a disk per application like General Ledger, Payroll, Accts Receivable, etc. The Operation System disk stayed "mounted" in its drive.
 
I remember the punch card systems and the 'Winchester' drives too.

Seems like a lifetime away now and yet it was only 30 years or so. How things have changed.
 
The Dumont not only made a TV set but it was the best on the market. The tuner was continous tuning right through the FM band. Not just hitting individual channels. When I was in Ham Radio the tuner was a collector item because the front end was really "hot".
They had a "Hi Fidelity" amplifier with two 6L6s in push-pull and a darn good speaker system. They were expensive but well worth it.
It was out done by "Mad Man Muntz" and his cheapo gutless wonders.
Funny thing about IBM cards. They have an mild abrasive in them and anybody in the "know" would keep one in your car if the points got pitted.
 
Helldiver,....if I'm not mistaken, "Mad Man Muntz" also promoted a car with his name slapped on it. Who actually made it and of what quality,...I don't have a clue.
















 
When I was in college in the 60s taking a computer science class we punched our programs on cards and then fed them into to the card reader. If your cards were out of order the program would not run. The biggest fear was accidentally dropping your cards and then having to put them back in order. Some programs had up to 1,000 cards.
 
Oh geeze! Yeah there are some memories ... First job I ever had we used punch cards to compile bills of materials for gas compressor support systems.

We had file cabinet upon file cabinet fulll of cards ... and if a particular part was needed, we had to go to the punch room and punch the cards ourselves. I remember sitting for hours in front of an old IBM punch machine running cards.

Sheeze.

Thanks for the memories HD! :d
 
I am too young to remember any of that stuff.



Or, is it, I am to old to remember?

:isadizzy:
 
Life sure was simple back then. One thread. One program at a time. Take turns, give the processor back to the command interpreter when you're done. Simple! I'll have to post a picture of my TRS-80 Model 4, which still works! :d

LOLOL.... Still works???? Dang.. Someday it will be worth a fortune..

My first computer, a TRS-80 model 1 (16K memory, level II basic), is still functional, but I gave it away to a friend who collects antique computers of all shapes and sizes about a decade ago.

His comment after trying the old dinosaur out was "WOW this thing is FAST!!" (as compared to a few others in his collection)

On 2 occasions, I helped him "rescue" a few pieces for his collection, including a 450# disk drive (the size and shape of a large home washing machine), and a 1600# DEC VAX minicomputer. Both of these had to be winched up a flight of steps out of a basement, and the people involved will probably remember this escapade a LONG time.

True story:
<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:eek:ffice:eek:ffice" /><o:p></o:p>
My first computer was a TRS-80 Model III. It had no operating system. Its “OS” was part of the “motherboard” and was basically the BASIC programming language. I learned a bit about BASIC programming with that box before I bought the Model 4. Now the Model 4 came with an actual operating system, TRSDOS, on one 5.25-inch floppy disk. I had no idea what an “operating system” was, or why I needed one, or why this “new” computer wouldn’t boot unless I had this floppy disk inserted into the drive. The old one booted up just fine without a disk in it. What’s so special about this disk anyway?
<o:p></o:p>
Furthermore, after booting, now the computer screen simply displayed the word “Ready>” at the top. So now what do I do? I tried typing, “RUN” and pressing enter. The box replied “Command not found” or some such. “RUN”, after all, was what you typed to get your BASIC programs to “run” on the old Model III box. But this one was “better”, and it didn’t understand, evidently, what “RUN” meant.
<o:p></o:p>
So I called my brother. He was smart. He’d know what to do. He suggested that I type “HELP”. I did, and low and behold, the screen filled with lines of text! Success!! But it was just a long list of seemingly meaningless words. My brother said they were “commands”. Type them in, he said, and they would “do things”. Awesome!
<o:p></o:p>
So I started trying each one, one at a time. None of them seemed to do a darned thing until I got to the one called “FORMAT”. As soon as I entered that one in, the disk drive started running! Wow! I wondered what it was going to do. Breathless I waited. Then the screen went blank. I waited. Nothing more happened. I tried “re-booting”, but the computer remained dead.
<o:p></o:p>
Yes, I formatted the floppy disk with the TRSDOS operating system on it.. Back then, nobody had figured out the “Are you really sure you want to erase your operating system? Press ENTER to continue” warning message concept yet…
<o:p></o:p>
I called the guy at Radio Shack and explained what happened. After he had finished “LOLing” his “AO”, he told me to come on down and he’d fix me up. He gave me a half hour crash course in operating systems and disk drives. He didn’t have to do that, but he did, and I always remembered that!
 
Wow, this thread brings back some memories. When I was a junior in high School I had been taking art classes all thru school and that was pretty much my and my parents focus, art. i had a falling out with the amazon of an art teacher and had to change electives. tried to get into architecture but it was full so I enrolled in a new program they had called data processing, not having a clue what it was about. All thru my Junior year we did the punch card deal working in Fortran and Cobalt and trying to understand flowcharting and logic, LOL. My senior year we hit the jackpot, the school treated us to brand new Apple IIe's and I got my first taste of basic and floppy discs, LOL (YEAH, no more punch cards!)
