I'd like an inexpensive computer for my neighbor

I was surprised at how small that machine is. It allowed my friend to redo her office space and free up lots of real estate on her desk, especially with the new, smaller footprint monitor I gave her. The new setup is really sweet.
 
I got roped into helping my girlfriend who wanted to buy a computer for her friend. She assumed I could handle it, so it ended up on my plate. What started as an inexpensive PC turned into a $1000 purchase after adding a service agreement because her friend couldn't manage it on her own. 🙄

The only difference I could spot was one takes 19.5v power adapter and the other takes a 19.0v one.

Oh, Sounds Good Not sure if I want to upgrade my All In One to a SSD Or Go with one of these.

Is this a Good SSD For my All In One? Either the 250 or 500 GB The 500 is only about $6.00 more.
Its A HP System Model 19-3013w

If you are happy with the speed of your current machine, that SSD will be a huge improvement over a spinning type hard drive at loading programs and files as well as speeding up boot times. On the other hand, the CPU (and everything else) in the newer BeeLink system you linked to is massively more powerful than your current one.

yeah it's not too bad for the most part.
big difference on the CPU l see though!
Would my All In One be able to upgrade to windows 11 when l install the SSD?
Would I have to buy windows 11 and how much does that usually cost?
Is this a good one?

No your current HP aio will not be able to install Win11 without the Rufus workaround. I would not worry about Win11 on that computer, just run win10 until it's dead (or is it still on win8.1?) and then buy a new PC in the future.

Thanks.
Yes currently running windows 10.

Probably. I'm not sure what NASA had at the time. Maybe a PDP-8?

The actual guidance computer had to be small enough and light enough to be in space. Despite being 16 bit it had about as much power as an NES. (Variants of the moon lander pc had 2-4kb of ram)

…..
The Apollo Guidance Computer had RAM of 4KB, a 32KB hard disk. It was fairly compact for its time, measuring 23.5 in x 11.8 in x 5.9 in, but weighed around 33 lb. Current computers are much lighter, at least thousands of times as fast and have storage capacities that around millions of times those achievable in 1969. ·

The original Apollo computer used 16-bit words for its data and instructions which was adequate for the local control functions. However, the navigation calculations required greater accuracy--"double precision," That is, more bits to get greater numerical precision, a feature implemented in the computer’s software. The Apollo computer had two types of memory--"erasable" and "fixed." Today that is referred to as RAM and ROM. The erasable memory was used as a kind of scratch pad for data and calculations while the programs were running (or for temporary programs). The fixed memory contained the programs themselves. All the erasable and fixed memory was known as "core" memory. That is, bits were stored by magnetic fields on tiny cylindrical cores. The computer comprised 1,700 transistors, each in their own metal can. There were nearly 20,000 metal and ferrite cores for the memory. Eventually the computer had 12,288 words of permanent storage, And 1024 words of erasable memory, It had a 16-bit architecture with only 8 instructions. For a control computer such as this, the interfaces were key –

It’s become fashionable n recent years to denigrate the Apollo guidance computer with phrases like: “we flew to the moon with less computing power than there is in my wristwatch", or "can you believe the entire Apollo program fit into a mere 36 k of memory? Simply focusing on memory size, or the computer's speed, however, misses the important point regarding the engineering accomplishments of the Apollo Guidance Computer. Even with today’s computers who among would you be so foolish as to risk our life on our desktop computer? Even with all the speed, accuracy, and memory available in today’s computers. And rely on their working flawlessly for two straight weeks?

For safety the Space Shuttle’s Orbiter flies with five redundant computers. And any fully digital airliner has a minimum of three. But the Apollo Command Module and Lunar Module had only one computer. There was not a redundant one on board.--and It never failed during two weeks of continuous operation.

Thanks! From what one of my professors said in college, we were well into the space age before NASA even got it's first computer. I was actually thinking of the ones sitting on the ground that NASA was using to compute orbits and other engineering problems.

NASA had various machines but IBMs 7090 series were the big Iron throughout the Moon years. For a time NASA was considered as having the most computational power in the world and the fastest computer in the world.

Other proprietary machines were used to store digital imagery from Satellites resulting in some moderately recent attempts to recover and restore tons of data tapes.

Funny part is it’s a lot more than 1000x

if I did the math correctly a modern smartphone would have about 3000x the ram and 100000x the processing power.

or as someone else said.. saying a smartphone is more powerful than the apollo 11 computer is like saying
Bill Gates has more money than me... same ratio. ;) :ROFLMAO:
