Weighing approximately 50 pounds and sized slightly larger than an IBM typewriter, the 5100 Portable Computer was announced by the company's General Systems Division (GSD) in September 1975. The Portable Computer was intended to put computer capabilities at the fingertips of engineers, analysts, statisticians and other problem-solvers. Available in 12 models providing 16K, 32K, 48K or 64K positions of main storage, the 5100 sold for between $8,975 and $19,975. The 5100 was available with either APL or BASIC — or both — programming languages.
If the size and weight of the 5100 seems huge by today's standards, then the Portable Computer was very slender compared to a late-1960's IBM computer with the equivalent capability. Such a machine would have been nearly as large as two desks and would have weighed about half a ton.
IBM offered three Problem-Solver Libraries, contained in magnetic tape cartridges (shown above), with the IBM 5100 to provide more than 100 interactive routines applicable to mathematical problems, statistical techniques and financial analyses. The cartridge had a 204,000-character capacity on 300 feet of 1/4-inch tape. The 5100 Portable Computer was withdrawn from marketing in March 1982.
Out of college the first job I had was programming the IBM 5110/5120 computers!
Wow does that bring back memories.
And in college the 400 level 'PC' class was with the 8080 pc. We saved our files by track and sector. The 'file names' were written down on a piece of paper!
Who respects, or other, when I arise her as a topic to be considered, hopefully with humanity involved and not politics.

Lefties, as you are for the most part persons more adept at technology than I, could you please, as Teddy would have laughed about, documented, use Mary Jo Kopechne's photo (avatar as you like) in homage to Teddy's Kennedyesque humor?
I say that not to capitolize or use spelling properly, but to bring attention to the care Kennedy's have, have had, and will have.
In 1974-75 I was representing the DC residential landlord community in dealing with the then-new rent control law. One issue was that the statute said that a landlord could get a rent increase if he wasn't making a "reasonable return on investment", but it didn't say what rate of return was reasonable, or how it was to be calculated. So the judge ordered the administrative agency to conduct hearings on that issue.
Somebody told me to use a particular guy as an expert witness on this. He was a real estate appraiser who had a portable computer to calculate the overall return on investment in any income-producing real estate, taking account of cash flow, depreciation, and capital appreciation.
The computer was, I think, a custom job, probably created just before the IBM in your video. It was about the same size, but more specialized -- it couldn't tell you anything about cattle feed.
It confused and intimidated the agency personnel who couldn't understand what it was doing, and certainly didn't want to have to buy one to run their rent control program. So they adopted a simple, workable approach to deciding what's a reasonable return, that anybody could use with a paper and pencil (or a pocket calculator if you didn't go to school in the days when they actually made you do arithmetic).
Some of the tasks they mentioned would soon be relegated to small calculators. You can still purchase the HP-12 and HP-15 that I acquired in 1985.
There is a Canadian network that is re-broadcasting 1960's action-adventure programs. We enjoyed watching "Batman".....BIFF....POW...ZONK. Next up, was a broadcast of an old "Lost is Space" episode. My adult age daughter completely lost it when the computer spit out a punch card that solved all the problems.....although the rest of the story was pretty cheesy as well.
I tried to explain to her that computers were smarter back then!

I don't know how many 5100's sold but they disappeared from the market by 1982, just after the IBM PC hit the market.
Little known fact - the project code name used by IBM when attempting to become a player in the wildcat days of the personal computer was "Acorn." Big bucks IBM almost bought out Nolan "Chucky Cheese" Bushnell to acquire his Atari 8-bit machines.
For the life of me, I cannot imagine pinstripe IBM associated with PacMan.
but this here tablet makes capital letters a sort of extra effort, and you cannot really have a cup of coffee while using the thing. things were more comfortable then, apparently.
its wonderful though how these people look like people, even in a commercial. wearing clothes too. refreshing.
i always thought hp made the first personal computers.

Ann,
Out of college the first job I had was programming the IBM 5110/5120 computers!
Wow does that bring back memories.
And in college the 400 level 'PC' class was with the 8080 pc. We saved our files by track and sector. The 'file names' were written down on a piece of paper!
Picturing my dog I thought:
There it is.
Nose.
Eye.
Ear.
Side view.
Portrait near if you wish to extrapolate like decent folks encourage and do.
now every teenager with a smart phone has exponentially more computing power and potential. they're not getting a thing done.
More, comedy, per one D. Burge or so I heard, is the idea of laughing at Ted Kennedy joking repeatedly about M.J.
Kopechne.
Teddy like laughable death ha ha.
Little motherfuckers didn't make Ted Kennedy's life easy though i.e. Fox News.
The most powerful amongst the right are impotent non-instapundits and therefore confused.
But one man, Mr. Jeff Fucking Goddamed Goldstein, has for over a decade defined the battle and set the terms.
We, as in I, and him, just need the funding.
70s.
Oy!
And The Blonde would still argue with the post title.
Love the smoked glasses that the paper mill guy is wearing. Smooth.

I'm thoroughly entertained now.

So the portable computer served its purpose.
It'll never catch on.

We got an IBM PC in 1984. I have it in my garage now. Its keyboard is much nicer than any keyboard currently sold. I should buy an adapter and use it.
People don't have interesting voices anymore.
looks very retro and sort of ugly.

Too bad it didn't come with a separate monitor that could sit on top. They might've had something then.
