I've an old 5150 which had spent the past few years up the loft in a box. I recently decided to put it back in use, but found it to be quite dead. 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.

Great article! I have one question though that I can't find the answer to. Does anybody know when IBM stopped supporting it?

I'm writing a history article and this and other old technology support dates are of interest to me but very hard to come by. Also if you know when major companies closed support to some machines like Macintosh 128k, etc. please, drop me an e-mail.

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).

Anyone got a 5161 or 5152 they want to sell cheap?

Here's a tid bit on the 25th Anniversy of the IBM PC... IBM used the Intel 8080 micro processor instead of the Intel 8086 micro processor because of the IBM System 32. 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.

Re: The date doesn't add up on the invoice. It is for 1/2/81. The IBM PC didn't come out until 8/12/81.

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.

I don't know where you got your info.

I have a large variety of software and extra's to go along with it. Any information would be appreciated. This is not a MSX GoldStar as far as I know and was made in Korea. Has a CGA Monocrome monitor. Base operating system is DOS with the main desktop Eight In One that boots as soon as the system is turned on. Has one 5 1/4 floppy drive. Has a internal hard drive, not sure about the size of the drive. Several programs including GW-Basic and a GoldStar monitor manual, I am missing the system manual. Also has a MS- Basic manual and a MS-DOS referance manual to go along with it. Apparently this PC was purchased on QVC and the PC was manufactured on date October 1989 according to the model information on the back. Also the serial numbers are 910003624. FCC #: BEJ9QKXT4.

Hi All: This is my first post on here. I own an IBM 3270 Personal Computer, It was rusted very badly so I gutted it and painted it. I am now looking for an AT board for it that will support a P4 processor, anyone have any ideas? Thanks....Mike S.

I used to have one of those when I lived in my apartment in New York on the 5th floor and it was by a window and my husband scared me and the window was open and I hit the screen and it fell out the window down 5 stories and it was gone. That old thing had good memories and then they ended up getting swept away with the dump truck.lol~

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

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. . .

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.
