Can You Do Real Work With the 30-Year-Old IBM 5150?

0 التعليقات
When IBM released its first personal computer, the 5150, 30 years ago, it was deliberately drab--black, gray, and low-key. That’s because IBM intended the 5150 to be a serious machine for people doing serious work.
So how better to celebrate this important anniversary than by using the 5150 for what it was meant to do? Working on a 5150 seems to be a tall task in today's vastly accelerated computing world, however. Could a PC that’s as old as I am manage to email, surf the Web, produce documents, edit photos, and even tweet?
I sequestered myself for four days amid boxes of 5.25-inch floppy drives and serial cables to find out. The answer to my question turned out to be both yes and no--but more interesting was all the retro-computing magic I had to perform. In the end, my experiment proved two things:
  • People now use the PC for many things that weren't even conceived of in 1981, and the 5150, unsurprisingly, is woefully underpowered for those advanced tasks. But when you use it for the core computing tasks the 5150 was designed for, IBM's first PC has still got game.
  • Early floppy discs were just too darned small!

Day 1: Setting Up

I was interested in spending more time with the Model 5150 because it's the foundation of so much modern computing. For the past 30 years, the platform created by the IBM PC has served as the basis for personal computing innovation and progress. Today, most people use PCs that retain some level of compatibility with a computer system released three decades ago.
When I first set out to test the mettle of the 5150, I realized that this special challenge called for a unique test environment. I couldn't pull this off at my house; I would be too tempted to use modern computers as a crutch. I needed a secret bunker, a distant location where I could wrestle with vintage technology unhindered and uninterrupted. (Did I mention that I have a one-year-old at my house?)
After careful thought, I sequestered myself in an infrequently used room in the upstairs corner of my parents' house. The bulk of Day 1 consisted of moving equipment over. I needed to take not only the PC itself, but also what seemed like 15 metric tons of supporting hardware that I could use for repairs in case the PC broke. Among those supplies were a few dozen ISA expansion cards (including spare video cards, serial cards, and the like), a couple extra 5.25-inch floppy drives, some tools, and a box of assorted cables.

Day 2: Trying to Fix the Thing

Day 2 began with a general survey of the PC. The first thing I did was open the case and assess what was inside. In the PC's five ISA expansion slots, I found a CGA video card, a memory expansion card, a floppy controller card, and a serial card for communicating with mice and other peripherals. For storage, my PC came equipped with a lone, full-height 5.25-inch 360KB DS/DD floppy drive. Thankfully, someone had maxed out the RAM at 640KB (yep, that's a massive 640 kilobytes--roughly 0.032 percent of the RAM on today's low-end PCs). When I looked for the processor, I found a surprise: One of this system's previous owners had replaced the Intel 8088 CPU with a Zilog V20 CPU.

The V20, originally designed by NEC, was a pin-compatible enhancement of the 8088 that could run certain programs 30 percent faster than the 8088 could--even though it ran at the same 4.77MHz clock speed. But it wouldn’t be historically accurate to run such a speed demon for this challenge, so I replaced the V20 with an 8088 chip that I had in my collection.
Next, I hooked the machine to my period-authentic IBM 5153 CGA monitor and booted it up. I briefly had some trouble with the video connector on the CGA board, but after I cleaned it a bit, everything worked fine. Then I encountered the next obstacle: a bad RAM chip. The POST error code told me exactly which RAM chip was bad (okay, I cheated and looked it up on the Internet using a netbook I had with me). Luckily, this socketed chip (a 4164C, to be precise) could be easily swapped out--but I didn't have a replacement on hand.
Despite the malfunctioning RAM, the machine seemed to work well. The 5150 contains, as the Apple II did, a full version of BASIC in ROM that loads right up if you don't boot from a disk.

Targeted mostly at computers without floppy drives (the lowest-priced 5150 sold with 16KB of RAM and no drives), this version of BASIC could save programs only to cassette tapes.
You read that right: Like other personal computers of the era, the 5150 came equipped with a cassette port on the back.

With the appropriate cable, users could save and load programs from a standard Philips compact cassette tape. The tech was slow and poorly implemented on the PC, but cassette players (and tapes) were orders of magnitude cheaper than floppy drives in 1981.

Stuck in 40 Columns

Once I booted into BASIC, I noticed that the machine's display was stuck in 40-column mode (that is, capable of showing only 40 columns of letters on the screen at once). As a business machine, the 5150 supported an 80-column display. Switching it was possible, but I didn't remember how.
Instead of a software-based BIOS, IBM equipped the 5150 with a series of dip switches on the motherboard for configuring basic system parameters, such as what kind of video card you're using, how much RAM the system has, and how many floppy drives are installed. I saw that all the dip switches on this PC's motherboard were set correctly for 80-column CGA, so I was stumped.
Next I booted into PC DOS 3.3 (PC DOS is what IBM called its version of MS-DOS) off a floppy disk. Still 40 columns. Then I remembered that there was some way to change the video mode in DOS. I thumbed through an authentic PC DOS 3.3 paper manual to find the solution: A DOS command called "MODE" sets the video mode. The mode I needed was called "CG80," which set up a color, 80-column mode in DOS. Yes, 80 columns at last!
Somewhere along the way, I decided to add a second 360KB floppy drive to make my journey easier. Thinking ahead, I had brought a half-height unit (pulled from another PC years ago) along from my house the day before. Doing serious work on a single-floppy-drive machine involves a lot of disk swapping, which is never fun.

The first images from inside the "slot end of the world"

I picked up a new photo from inside the giant hole that suddenly appeared in the Earth's surface, and images quickly spread around the world with increasing interest in scientific views of this phenomenon.

The multiplicity of theories pay the government authorities in Yamal to call a mission of experts to find out the real reason for the appearance of the hole in the ground in this region.

I picked up the scientific mission of many important images of the slot, including by helicopter, and the pictures were published in the newspaper The Siberian Times, the scientists also used satellite images from Russian to see an instant form the slot.
The data indicate that the mission to the slot depth of 70 meters, and in the glacial lake bottom and Tnsal water ice on the walls of the hole corroded.

Despite the insistence of the team of scientists that hole, "a natural phenomenon", but they emphasize the need for further study to determine the reasons for their formation like this huge and deep.
Scientists have observed also that the aperture diameter is smaller than Kdrōh previously, said Andrei Plekhanov, a researcher at the Center for State Scientific Research Arctic The nozzle hole take the form of elliptical rather than circular, what makes the measurement aperture diameter accurately is difficult, but they appreciate by about 30 meters, With the addition of the burnt edges of the measure becomes a diameter of about 60 meters.

Scientists have been able to go down into the hole, but they were unable to get to the bottom, and noted that the ice accounts for about 80% of the components on the walls so that the bottom has been taken gradually to melt under the heat of the sun.
Some scientists likely to be high summer temperature in the region of Yamal past two years 2012.2013, the impact may be in the slot, but others believe that the best theories put those attributes posed to the causes of "internal" out of the ground does not "foreign."
Scientists say: "We can now say with certainty that under the influence of internal processes in the ground there was a" centrifugal "of ice, and that what happened was not an explosion, which means that there were not associated with the heat of the opening is."

This calls for speech theory emerged in the eighties of the last century, scientists have neglected for several years, and says that the Yamal area lakes were formed due to such "natural processes" that occur in the ice beneath the surface of the earth.These processes have been happening since about the year 8000, and perhaps now is the repeated, ie, we are witnessing a new phenomenon of the lake again.
The proof of this theory means that we Nasr natural process is unique, the foundation was formed in scenic nature of the Yamal Peninsula.
On the future of the pit, said Marina Liebman, the researcher first at the Institute of the cryosphere of the Earth branch of Siberia to the Russian Academy of Sciences: "the walls of the crater will melt down, and with high temperatures in the summer there will be no time to freeze again, the water will top the water level inside the pit, and we are probably in front of the formation of a new lake.

The All Seeing Eye and #Illuminati Control/Power #freemasons #Masonic #newwordorder

Although many of you will object to this, those with keen eyes know that the symbolism of the All Seeing Eye is literally everywhere. This is no question. The real question is why? Is it just a cruel joke by unassociated individuals to mess with the heads of conspiracy theorists? The way I see it is that these symbols are used today as marks of ownership as well as to mark things that contain symbolic significance containing a message. The elite are not so careless as to mark their innermost texts with these symbols. However, some things, such as logos, are marked with these symbols. The focus of this writing will be on the All Seeing Eye. First I will explain some of the meaning behind the All Seeing Eye. 
The All Seeing Eye is a symbol comprised of an eye within a triangle. Often light is shining down from the eye. It is called in Freemasonry the Eye of the Great Architect. There are two explanations to the symbol of the eye. The first is that some believe the eye to be the Eye of Ra, an ancient Egyptian sun deity who is also a manifestation of the god Amen [Amun], known as The Hidden One. The other explanation for the eye is that it is the Eye of Horus, which I find a bit more interesting. 

Horus, also originally a Sun Deity, later became attributed with being a sky/duality deity, representing both the Sun and the Moon, with his right eye representing the Sun, again called the Eye of Ra, and the left eye representing the Moon, called the Eye of Tehuti. Interestingly, Tehuti is also known as Thoth, who in occult circles is known as Thoth Hermes Trismegistus, or the Thrice Greatest. He is also known as Hermes to the Greek. Thoth Hermes Trismegistus is a knowledge bringer [Luciferian/Promethean] deity accredited with divulging the divine sciences of Alchemy, Astrology, and Theurgy to humanity. Some also credit him with mathematics, language, among other things. In the esoteric view, Thoth Hermes Trismegistus is believed to have been at one time an actual person who was eventually deified... 

The All Seeing Eye usually features a LEFT EYE.

But first of all, DO these symbols actually appear on things tied to the elite? The answer is yes.. but is it all just coincidence? 

1) The Information Awareness Office logo: 

Funded by DARPA, the Information Awareness Office's stated goal was to collect as much information on everyone and everything as possible. This drew much flack to them and the IAO was discontinued. However, its core projects still continue under different names. The logo depicts the Illuminati pyramid with All Seeing Eye shining its light over a globe. 

2) The MI5 Logo. Military Intelligence Section 5. 


3) Fidelity Investments Logo: 


4) AOL logo: 



However, what is more interesting is that these symbols are all over popular media since as early as the 60s and 70s in very hidden and yet deliberate places. So either all these different artists/people are purposefully putting in these symbols just to mess with conspiracy theorists, or there is some greater power at work: 

4) For example, here is Madonna bearing the symbol on her back. The name Madonna also has obvious esoteric significance: 


5) All Seeing Eye flashed in Nickelodeon logo, along with CBS logo type eyes. If they are just putting it in to mess with the minds of conspiracy theorists, why would they put it here? How many conspiracy theorists watch Nickelodeon, and why was it flashed quickly as if it were a subliminal [note this is back in the 90s]?: 




6) Michael Jackson's Dangerous album cover contains the All Seeing Eye as well as the Skull and Crossbones. It is a goldmine of occult symbolism.


Some people believe that Michael Jackson was actually killed by the Illuminati and had been subjected to character assassination in the years prior. This is due to a recent comment by Michael Jackson about a year ago speaking out about the Illuminati, hinting that he was going to utilize his then upcoming "come back" world tour to spread his message and awareness, particularly with a song called "They don't care about us." The music video for the song depicts a rural third world country where Michael is dancing with the people, while UN Peacekeeper looking people stand by monotonously giving a fascist presence. In one scene, Michael is seen dancing next to an all-seeing eye that is painted on the wall. 

7) Here is recent pop sensation Lady Gaga. Her backup dancers bear the All Seeing Eye symbol on their backs: 


Now Lady Gaga is an interesting character. As we all know, music, television, etc.. all influence people in large and yet subtle ways. Lady Gaga's musical message is one of emptying thoughts and acting as one feels, exemplified by her song Just Dance. It is basically Orwell's concept of Bellyfeel from 1984. She is often shown speaking in a robotic manner, or acting as if she were mind controlled. Whether or not this is just her public persona it is definitely interesting. She is also often seen with butterfly symbolism, which is a direct reference to MONARCH Programming.. but there's more. 

The word "gaga" roughly means a sort of astonished stupor, for example "he was gaga over that girl." It is also a direct reference to the Queen song, Radio Gaga. In the music video for Radio Gaga, many scenes from the 1927 movie Metropolis was used. The movie Metropolis is about a woman who is chosen by a futuristic scientist to be "sacrificed" in a black magic/scientific ritual in order to give life to a robot. The experiment is a success and the now alive robot also proved to be very popular among the people. Then the scientist in the movie utilized the public adoration of the robot with the aim of manipulating the public into doing his bidding. His goal was to cause the public to destroy themselves [they end up unwittingly killing their own children and destroying their city]. 

Lady Gaga's symbol is that of a headless mannequin with a lightning bolt through it. This of course symbolizes a body which is charged with some sort of outside force that moves it. Mind control themes are often referenced in her songs, which also contain many other occult symbols such as that of associating her with Baphomet, a hermaphroditic goat-headed and winged deity representing the dualistic principles "as above so below" and "order out of chaos." She is also rumored to be a hermaphrodite herself. 


Another thing of interest is that she had an entire photo-shoot in a Masonic Temple, in which she had eyes painted onto her eyelids and took the series of photos with her eyes closed. The esoteric significance of this symbolism is obvious.
