The IBM Personal Computer

IBM introduced its Personal Computer to much fanfare on August 12th, 1981. The PC was developed in an astoundingly short time (under 1 year) by a "skunkworks" project at IBM's Boca Raton Florida facility.

One significant reason for the rapid development cycle was the use of "off the shelf" parts for things like disk drives, processors, memory and the like.

Another "off the shelf" component used on the PC was IBM's Operating System software - PC DOS. This product was licensed from Microsoft after the IBM development team were unable to secure a license for CP/M. The use of Microsoft's product on this machine helped catapult an already successful company into its current dominant position.

The PC pictured here is one of two in my collection. This is an original PC variant with a 64K motherboard (as opposed to the later 256K motherboards) and version 1.0 ROMs. It normally has a color graphics adaptor (CGA) and an IBM 5153 Color Monitor as well as a multi-function card and some other accessories although the Monochrome monitor (IBM 5151) and IBM Monochrome/Printer Adapter card are probably more correct for the machine. The system has a full suite of original IBM documentation including the 1.0 versions of DOS, BASIC and the IBM PC Guide to Operations.

Microsoft Adventure

I have lots of original software from IBM and other sources including CP/M-86, VisiCalc, PFS:Write and much of the original IBM library of games and educational software including the BASIC Primer, Typing Tutor, Adventure and the "Microsoft Decathlon."

Lots of Microsoft Docs

I also have the IBM PC Technical Reference and IBM PC Maintenance and Service manuals.

The other PC in my collection is a later model with a Monochrome card and an IBM 5151 Monochrome monitor.

IBM PC manuals

Both of my PCs have all of their original manuals, as shown here. The three manuals to the right are all 1.0 versions, including DOS 1.0 with the original DOS disk.

IBM PC Keyboard

The IBM PC Keyboard was a very sturdy, well designed 83 key model that had far better key placement and a better feel than any other low-cost computer of its day. IBM did everything they could to sell the ideas of "professional" and "sturdy" with their machines and they succeeded without question. Even the function keys were a hit!

IBM 5.25 inch floppy drive

IBM made the PC with as many off-the-shelf parts as possible. That didn't stop them from stamping them with their name and logo, though. This is a standard Tandon 5.25" disk drive except for that IBM logo.

The reciept for my first computer, purchased by my Dad

IBM sold the original PCs for around $1,600, but that was just an advertising price for the 16K system unit with a keyboard. Once you added a video adapter, some RAM and a disk drive or two you could easily climb to double that price. My first PC was purchased by my father and cost nearly $2,800. It had a single disk drive and 64K of RAM with a CGA card to be hooked into my TV set. I eventually got a black and white composite monitor so I could see 80 columns and a Quadram Quadboard that allowed me to expand the PC to nearer its 544K limit.

Front of the IBM Fact Sheet
Back of the IBM Fact Sheet

IBM did an all-out media blitz with the introduction of the PC. The card above is one of several I collected from local computer stores while waiting for my PC and it is one of the few advertising items that didn't feature Charlie Chaplin whose visage IBM licensed to represent their machine.

DOS 1.0 disk label

Perhaps my favorite aspect of this original IBM PC is the fact that I still have my DOS 1.0 manual and disk with it.

DOS 1.0 Running

DOS 1 was such a crude and simple operating system as compared to later versions or even CP/M. It was, however, easy to learn and starting from 1.0 meant that I only needed to learn a bit of new stuff with each iteration.

DOS 1.0 did have a nasty math bug, though, that was fixed by a patch - version 1.05. I've got a copy of that as well. IBM never officially released that version, however. It was just a bridge version until 1.10 could be shipped with the fix and some new features.

DOS 1.0 Booting close up

On boot DOS would ask for the date and then drop you to an A> prompt. There was no colon and there was no C> because the original PC wouldn't support hard drives or sub directories.

The PC also didn't have any sort of BIOS configuration utility. The system was configured by setting up a couple of sets of dip switches on the motherboard. One switch indicated whether you had a monochrome or color card installed. The one next to it indicated the default video mode (40 or 80 column.) Others set memory size.

As compared to today's multi-gigahertz, multi-gigabyte machines the original PC is crude and primitive.

But with its introduction in August of 1981 the world of personal computers was forever changed. The PC effectively killed CP/M and the S-100 bus and many of the companies that supported them, although those technologies clearly lived on for quite a while past 1981. Microsoft's shrewd decisions with regards to the DOS licensing agreement allowed them to sell DOS to other companies who produced PC clones. With every PC went DOS and with every copy of DOS Microsoft's dominance grew.

With the PC Intel went from being just another player competing with Zilog and Motorola to being the undisputed king of PC processors for two decades and probably more. In fact, much of the technology from the original PC lives on today as legacy support in the latest Microsoft operating systems.

Even when that's no longer the case the PC will still stand in the PC hall of fame next to other influential and landscape-altering machines such as the MITS Altair 8800 and Apple Macintosh.

I've got a weird PC add-on that's looking for a good home. Its an Apple II built on an ISA card -- its not a clone, its the real thing. AFAIK it still works, although obviously I haven't run the thing for years. Its free (P&P appreciated) to anyone who wants it...

I might have some other PC junk in the attic but I don't think there's anything interesting except a software package that allows PCs to read CP/M floppy disks. (I've got a complete, allegedly working, Corona PC clone up there, its one of their transportables, but if anyone wants it they'll have to come 'n get it.)

I have the original IBM BIOS manual that contains the complete fully documented bios code. I bought this when I bought my IBM 5150 in 1983. It was quite the popular borrowed book when I was consulting at GM because many of the folks I worked with were writing MASM Assembler device drivers and telcom software. I still have my 5150 with upgrades from PC Limited (aka Dell), but am missing my color monitor which I lent to an ex brother-in-law and never got it back. Would love to find another monitor and boot up this baby! Regards from San Diego.

Thanks for the correction on the receipt- I should have guessed 1/2/81 was a slip-up due to the New Year's festivities. I also found out that the Osborne 1 was ready for sale before the IBM-PC, in April/May of 1981 (in time for the National Computer Conference in May, 1981). That model was officially the first laptop ever, but as you know the screen was almost like the modern day Ipod in size! Talking about archives :-), I just ran into a fascinating interview on a show called Computer Chronicles hosted by Stewart Cheifet and Gary Kildall (of DR fame): ~~ http://www.archive.org/details/Computer1984_5 ~~ In this episode we see Gary Kildall, Digital Research; Steve Wozniak, Apple; Adam Osborne, Osborne Computer; Lori Harp, Vector Graphic; Gene Amdahl, Trilogy Systems. I really enjoyed watching Computer Chronicles on PBS in the 90's, and found Stewart Cheifet to be a most entertaining and affable host (1981-2002).

The Aug. 12, 1981 date was very well publicized.

The 1/2/81 date on the receipt was just a typical New Year's hangover where the clerk forgot to change the year.

The actual purchase date was 1/2/82 although it was ordered months prior to that.


(Submitted May 23, 2009 09:59:42 by Stephan)

Erik: I have been puzzling over the actual date that the IBM-PC was first introduced. I have seen in a couple of places, the date April 24, 1981. ~~brainyhistory.com is one of those. Your receipt pictured above for your First Computer- purchased by your father- shows the date 1/2/1981, but that computer was probably not officially an IBM-PC, but a customized version with some IBM parts. Then there is the date Aug. 12, 1981, familiar to us all. I suppose there will never be agreement as to the actual First-Release date, since it depends on who you ask! Maybe 4.24 was like a sneak preview for 8.12, at one of those computer conventions. They are related after all, since *8*=*4*x2 and *24*=*12*x2. Who knows what the marketing gurus had in mind?

The power supply is fine, but the motherboard seems to have given up. Does anyone know of anywhere, preferably in the UK, where I can find parts for this great computer?

On a philosophical note, I would dare say the green monochrome display is so ingrained in our collective (sub)consciousness that it has become the defacto symbol of the cyber-culture as represented by the Matrix' movies.

I bought my first IBM pc in 1981. It cost $6,000! It had a 20MB hard drive which was built by someone other than IBM. It had a uni- directional Epson printer (MX-100), a monochrome monitor. I found some company in Boise, Idaho that sold me an indexing system for BASIC, since IBM's BASIC had no way to directly access a file other than by record #.

The DOS language had a quirk. When you keyed the FORMAT command, if you forgot to key the drive letter (A: or B:), the darn thing would default to C: which was of course the hard drive. Did that a couple times before I stopped making that mistake.

I programmed it at my office. I was taking it to the customer so I carried it out to my car, lost my grip and dropped it on my foot. It broke my big toe.

Hey Erik,

Any chance of putting the DOS 1.0 dsk image up on your site or emailing it to me? I'm sure IBM'd be OK with the copyright side of it given that (a) They sold their PC division to China last year (b) It has no commercial value or application (c) They would have dropped support for it an eon ago.

You can get all the tools to do the imaging (plus many many old IBM booter images at:)

That's interesting to see CP/M-86 in an IBM slipcase. I always thought DR marketed it themselves. Boy DR were dumb... if they had priced it lower than DOS then end-of-story but apparently it was worth like $500 compared to about $50 for DOS and DOS was so much more underpowered (I have used CP/M-86 on my 5150 and it's a real step up from DOS 1.x-2.x).

IBM used the Intel 8086 in the System 32 and was afraid that if the Intel 8086 was used in the IBM PC that some interprising soul would figure out how to get the System 32 OS to run on the PC and thus cause a loss of sales for the System 32...in the end, some one figured out how without IBM's help...:)[/quote]

This is total BS. I was a Customer Engineer for IBM and trained on the System 32. It was introduced before the 8086 was available. It was an 8 bit processor machine derived from System 3's and the 8086 would blow it away.

You're right. The date only adds up once you realize that a lot of folks have trouble remembering the change in year right after the new year. On January 2nd many folks are still a bit hung-over. The machine was actually picked up on 1/2/82 even though it was ordered months earlier.

@Ron Mitchell - It was in an 8088, not an 8080. They used an 8088 because 8-bit components were cheaper and the 8088 had an 8-bit bus compared to the 16-bit bus of the 8086.

Hi all, Erik this ones for you, since you have all the instruction books and original disk is there any chance that i could say, buy a copy from you? They don't need to be originals its just hell trying to find software of this age anywere, i am after pre 2.0 DOS and the diagnostic disk for an ibm 5150, and help is much appreciated, Thankyou, David

Anyone care to guess what a working IBM 5161 Expansion Chassis might be worth? I have a complete unit with a 10M hard drive installed, sender and reciever cards, that ridiculously thick cable, and the manual taking up space in my basement I'm thinking of selling...

Sorry Interlace, but I have to kick you into touch with your above post (second from top)... the standard machine came with 64Kb on the mother board as standard, to extend the memory, you needed to either upgrade the memory chips or use a ram extension board (Quadram for example) As far as I remember, the standard shipped out mother board had 16 4KB memory modules on board, but absolutely did not have 640KB of memory modules as standard... no, you paid extra for those, along with your hard drive and your monitor.

Oh! great computer. My 5150 is still working well EXCEPT it's hard drive. I've got to reinstall PC-DOS again, but I haven't found 5.25 disks. Anyway, someone selling them??? ;)

My dad had an 8088 XT (ibm) when i was little, with a monochrome adapter and a monochrome monitor that displayed orange (ahh.. nostalgia) :) I remembered using HGCIBM to emulate CGA for games (which was extremely cool hehe), i also believe that was the tool that could give a boost to ega adapters (mentioned a few posts above). Only one correction to what's mentioned above.... it had 640kb memory (so i don't think 512kb was the max back then). Oh well, those were the good old days.

The 4-color limitation was only a limitation of the CGA memory. With 16K memory, it could do 2-bit color at 320x200 (320*200*2/8 == 16000) or 1-bit color at 640x200 (640*200*1/8 == 16000). These are the modes directly supporeted by the PC BIOS; with a little bit of manipulation of the CGA registers, though, one could achieve 4-bit color at lower resolutions. I don't remember the details, but I remember playing with some old code from Compute or BYTE magazine that did this; I was truly amazed.

i really like this page and i was just wondering if you could send me the recent upgrades to the IBM computers since 1975 when I think that was when it was first started.

Thank Michelle

Can you mount a 1.44mb or 1.2 meg drive in there and just configure them as 360 and 720 my 5 1/4's are no good anymore.

Graphical User Interface. -like windows XP or just plain old windows itself. DOS is a non-gui

But whats a GUI

GUI is a Graphical User Interface. That means interacting with a computer by doing something other than typing command line text strings.

Windows and Apple and OS/2 and many other operating systems are GUI. If you have to type things like C:/qbasic or edit in order to run programs, you're probably not running a GUI. If you are using a mouse, pulling icons around, etc, then you're using a GUI.

Here's a place that explains GUI in more detail:

I was surprised that a commenter in Dec of 2004 was eschewing Ebay because it would require a GUI. I presumed the comment was tongue-in-cheek, though I suppose it was not.

Jeff,

If you don't want to do eBay or the Vintage Computer Marketplace you can just accept emails from here and, hopefully, someone will want them.

You can also post something to one of the appropriate newsgroups. . .

Erik

I've got two 5150's in my garage...haven't had it in me to toss them (thinking they may be worth something someday...) Any idea how best to unload them (I'm not much for ebay...need a GUI for that)

There were differences between the early PC and the later XT. The PC had five slots, spaced further apart than usual, had two DIN connectors on the back (one for keyboard and one for cassette), and had a feeble 67 watt power supply. The later XT deleted the cassette port (though the BIOS continued support for it), at least a 120 watt power supply (IBMs I have seen used 120, 150 or 180 watt PSUs), an 8 slot motherboard. The PC could only support 64kB memory; the XT supported 256kB (512kB with special piggy-back memory). The PC had two sets of DIP switches and a relay for the cassette, the XT had one bank of DIP switches. The earliest PC's had a built in cassette with no floppy, like the Adam had...

A GUI, Bobby, is a Graphic User Interface. I pulled an IBM PC out of a dumpster at New York City's World Trade Center back in the late 1980s/early 1990s and still have it. I actually mail ordered some additional RAM a while back and took it up to the full 640K. I used it as recently as 1997 but have not booted it in years.

the CGA display supported only 4 colors @ 320x200

I remember that...thing...being in my house way back, my father worked for them. It was cool just to see numbers on the screen!!! Didn't work like a calculator though...you had to put in formulas or code or whatever it was.
