| INSIDE PC |
|
A modular concept which allows user to add, remove or exchange any part of the computer.
**(1)** Expansion slots for add-on cards. There are only five of these ones, which is almost too much for the 63 Watts power supply which cannot handle high power cards.\
**(2)** Intel 8088 microprocessor. Next to it is an empty socket intended for an Intel 8087 math. coprocessor.\
**(3)** The power supply is equiped with a security system which automatically cut the power in case of short-circuit or overheating.\
**(4)** Floppy-disk controler card. The first PC was equiped with full height, single sided, single density, 160 Kb disk-drives.\
**(5)** Disk eject levers.\
**(6)** First PC motherboards included 64 Kb. RAM. Note that each row of memory circuits is composed of 9 chips, eight for memory plus one for parity control.\
**(7)** ROMs holding the BIOS (Basic Input Output System) and the IBM Basic written by Microsoft. |

1983 - Before the IBM PC became THE universal standard, IBM was looking for good programs using all the features IBM Basic could offer.
Advert said:

This was my first PC repaired by my hands and with only basic aknowledge in electronics.\
The 5150 was set at our Library and an memory error mesage appeared when you powered on.\
It had a bad memory chip and I didn´t know how to fix it.\
So I found the solution in Brenner´s book which deserve my respects at all. |

"Jeffrey H. Ingber" is remembering history wrong. I built literally thousands of machines when working for resellers in the Los Angeles area. You could order a PC with no drives, one drive, or two drives. The XT came out of the box with a 5 1/4" drive and a 10mb hard drive. You could order them that way right out of the box, and take them home.
Now, what alot of operations did was customize. Pull out the single drives and stack two 1/2 height floppy drives. Order the XT with no hard drive and put in a 20 or 40mb hard drive with its own controller.
The idea that you "couldn''t" go in and get from IBM a machine ready to run out of the box is hogwash. People did it all day, every day. The biggest sellers for home use were two drive PCs from the factory, and standard XTs with the hard drive from the factory. Hughes Aircraft, Rockwell and others would order XTs without the hard drive and have third party Seagates put into them$by the THOUSANDS. Our config center would crank out hundreds of machines over a weekend, so I know what I am talking about! |

my old man brought one of these from work back in about 93-94 for £50 i had it in my room $ spent much of my childhood using one for word processing $ playing games. in order to play a game or load a floppy you had to enter a command as they wouldnt just run otherwise. our one had on floppy drive $ i wasnt much for the screen as it would get whatever you had been doing burned onto the screen, plus it used to give me headaches which no other monitor has ever given me lol i owe alot to these PC''s as they started my interest in computers which i still have today $ has been a lifelong hobby. unfortunately when we moved house it got left behind in our old house $ i do miss it alot, i would definitely buy another one |

I''ve done some extensive research about the MS/DRI debate. As Tom Rolander (DRI) states in many interviews, DRI was indeed interested in having their OS in the IBM PC. Gary Kildall and Rolander did meet IBM executives, there were some early licensing disputes (it seems that IBM wanted to buy the whole CP/M 86, while DRI obviously preferred a licensing scheme). IBM then involved Microsoft to have an OS ready for the PC launch.
Microsoft proceeded with buying QDOS from Tim Paterson - who wrote it in 6 weeks QDOS - many suspect it to be a CP/M ripoff.
After some legal threats from DRI against IBM, both a completely rewritten MS'' QDOS (due to bugs, IBM had to rewrite it fron scratch), branded PC-DOS, and CP/M were given as an option to PC buyers.
As DRI''s Rolander recalls, when the IBM PC went on sale, CP/M option was priced $ 240, while Microsoft-IBM PC-DOS was priced $ 40. |

I had one of these old beasts. I had the Hercules Graphics card and an Amdek amber-on-black monochrome monitor. It did indeed have the 8-bit slots but there were only 6 of them. The XT had 8. Most of the chipsets on the board were made by texas instruments although I do also remember seeing hitachi and samsung chips as well. I remember this because when I was 12, I took the thing apart right down to the screws and rebuilt it again. This computer is the reason I know how to build PCs today. (Like my Phenom II system I just built last week! LOL!) The upgradability was fantastic for its day and at the very end, I had an AdLib sound card and an ATi EGA Wonder. Ahhh, the carefree days of my youth. I actually even ran my BBS on it with a 2400bps modem for over a year. *grin* my BBS, Seventh Heaven can currently be found on the historic area code 416 BBS List.\
Oh yeah, one more thing. It took a full 2 minutes for the thing to boot once you managed to get your hand to the back of the case to flip the power switch. |

Bill Gates didn''t have an OS so he SENT Jack Sams to see Gary Kildall about CP/M. When Gary''s wife Dorothy turned them away, Bill realized that he needed to get an OS or his deal with IBM might fall apart. |

The reason IBM did not go with CP/M is that two guys in IBM garb showed up at the CP/M location in Sunnyvale (which was a home) to discuss that IBM was going to build a PC. The husband wasn''t home and, before they would even tell the wife who they were, they asked the wife to sign a 22 page disclosure (standard for IBM when working with other OEMs). She was so overwhelmed and confused that she threw them out. They then called back to their manager who suggested that, since they were already on the west coast, they go up to talk to "that guy who wrote the basic". |

In 1983 we were a new government program and my boss, a great visionary - who none-the-less considered a pencil to be a portable printer, my boss knew this "PC Thingy" would be important. Because I had been playing around at home with TRS-99 he appointed me to be "the computer guy."
We purchased an IBM PC with an 8086 chip. It was the second PC in the entire State Employment Agency. Two floppy drives and one 10 megabyte hard drive in the expansion chasis. (During design phase I requested a 20 megabyte hard and I was told by our "expert" - '10 megabytes is more than you will use in a life time.')\
I later added a second 10 megabyte hard drive in the expansion chasis. dBase II was the main piece of software I ran, with some word processing with WordStar.\
By using the PC to organize data collection we were able to demonstrate the effectiveness of our programs and we continue to serve the people 23 years later.\
I have retired now, but thousands and thousands of young people owe a great start in their working life to vision of that one guy and the use of the IBM PC. |

To John Cowley:
This reply comes a year later, but regarding "Non-System Disk or Disk Error," the answer is quite simple:
In order to boot up properly, an operating system is required. As these computer systems only came with floppy drives (originally), you must start the computer with a "Boot Disk" in the first of the two floppy drives.
Assuming the disk has the necessary system files on it, and it has not become corrupt, then they will allow the operating system to load into memory. If successful, you will come up with a DOS command prompt.
During a time before the success of the mouse, the IBM PC and compatible computers ran completely from a command prompt. From here, you can swap diskettes, enter commands, and launch programs. But without a "System Disk," to tell the machine how to talk to it's hardware and peripherals, the computer is unusable. |

Back in the early nineties I bought one of these second hand and wrote my entire four years' worth on university work on it! Mine had a hardcard - a 30MB HDD on an expansion card - in it, which made things a lot easier. Those were the days: DOS and WordPerfect 5.1 !!! |

My dad used to use these at his job. The drives were so primitive, so they liked to eat disks. Can you attatch a 3.5 floppy on this? |

To Maja - IBM-PC is copyrighted, but it is very hard to prevent somebody to do some reverse-engineering and build a 100% compatible machine from scratch. In IBM's case, that was Compaq, I belive. IBM even sued them over copyright infringment of the BIOS code, but they lost, as we can all see. And rightfully so - reverse-engineering is not the same as copying and if done in the spirit of "fair use" - perfectly legal. |

Hi. Does anyone happen to know, why IBM did not patent the original PC? I mean, how did it happen that everybodey started cloning the thing. Was that IBM's intent or did it happen by accident?\
If anyone knows,I'd much appreciate the info.\
Tnx.\

Microsoft Flight Simulator 2 was the best hardware compatibility test software to evaluate IBM PC clones!\
The PC keyboard had an excellent feei but was VERY noisy and CGA output in text mode was flickering when scrolling text. MDA display was eye-pleasing and character generator supported accented letters; great tought for non-English users! |
