The IBM Portable PC was IBM's answer to Compaq and their Portable. The IBM machine boasted 100% IBM compatibility, of course, whereas the Compaq couldn't quite get there (mainly because they couldn't put BASIC in ROM).

The IBM Portable PC was actually a tiny bit smaller then the Compaq and just a little less expensive. The competition spurred Compaq to produce some smaller, more powerful and less expensive machines.

The back of the IBM PC Portable

Seen from the back the Portable PC has all of the ports and slots typical of an IBM XT.

A closeup of the IBM PC Portable screen

The screen on the IBM PC Portable was one of its strong points. The bright amber display was both attractive and easy on the eyes. Just for fun I booted up DOS 1.0 on this portable (they typically shipped with 2.0 or later) to see how it looked.

The PC Portable was a transportable machine. This one came with the optional IBM carrying case made of sturdy blue canvas capable of holding the considerable weight of this machine.

I have one of these, still works fine. I'd like to sell it but I see it's not really worth much. Oh well, maybe my grandkids can sell it in 30 years.


(Submitted December 1, 2010 23:32:46 by Dominic)

I've got one, that still works perfectly.

Does anyone have a (on 5 1/4 floppy disk) copy of the word processor Textor that was running on it. I've got old files / archives I'd like to edit again.


(Submitted November 9, 2010 10:02:04 by Keith)

I have one of these that works fine if you're interested and will pay the shipping...

I'm thinking about parting with a working full desktop setup, including the luggable w/640K *AND* the math coprocessor (8084), an IBM RGB color external monitor, and IBM PC XT expansion box with 2 10MB HDD. Pretty sure I still have the original DOS diskettes and manuals, too. LOL! Anyone interested? Its quite a conversation piece. :-)


(Submitted June 26, 2010 14:07:14 by Jacob Moore)

I have one of these that won't power up. The PSU fan spins for a second, and the floppy drive lights flash briefly too. If anyone has any suggestions as to what is wrong, or if someone has a service manual, or even just the PSU section from a service manual, that would be really appreciated!

Thanks, Jacob

I live in San Jose, Ca and have retired from IBM after 42.5 yrs. This June my wife is hosting a retirement party for me and I would be interested in 'renting' an original IBM Portable Computer to display during the party. Does anyone in San Jose have one and willing to rent it ?

The 5155 I had for sale in my March 25, 2008 comment below has now been sold!

The IBM Portable PC I offered in the March 22 post has been claimed.


(Submitted March 22, 2009 19:31:07 by Eric)

I've got a working IBM Portable PC that's free to anyone who can pick it up in San Ramon, CA or I can ship it if you'll pre-pay the shipping. It powers up and runs the built in BASIC. It comes with the original IBM carrying case and has a 640KB memory upgrade. I don't have any floppies or manuals.


(Submitted December 14, 2008 15:26:49 by Zane)

Are any of these available for sale at a price range of $0-25. I would like to buy one.


(Submitted April 15, 2008 03:31:14 by Terry)

if anyone has one of these to donate or sell at a reasonable price, i'd be interested.


(Submitted March 28, 2008 20:03:51 by Steve)

Oh! I could kick myself now, but back then... Been browsing the site and looking at all the old dinosaurs, and remembering. I had one of these back around 93-94, and put a 486 board in it, just to see if it could be done. Modified the drive bay to take the 3.5, and had a real hot-rod! I'm guilty of mod'ing PC's, XT & AT's, a Kaypro, and others. O! The tragedy!!


(Submitted March 25, 2008 20:22:36 by John O'Callaghan)

I have a working IBM Portable PC and I have decided to sell it, or trade it for some vintage Intel chip(s). Anyone interested, please contact me at 773-572-6461 (work). Chicago area...thanks.


(Submitted February 16, 2008 11:28:24 by Nick Darley-Jones)

I have one of these and it works! Spent most of the 80s-90s writing software in IBM basic.

Planning to sell it complete with Case, manuals and disks! Haven't fired it up for about 15 years. Will be sticking it on eBay. I hope someone can pay the postage!


(Submitted December 6, 2007 13:18:49 by (a href=mailto:)John(/a))

I have one in my living room. 640K ram, 40Mb SCSI hard drive with matching black front, Dos 5.0, USR 9600 Baud modem and windows 1.1.

FYI - the IBM 5155 I had for sale is gone. Thanks!


(Submitted September 27, 2007 10:24:18 by HG)

I found one of these years ago complete with the carrying case. I asked how much for it and the guy just gave it to me. Not a scratch on it and works. I figure if I hang on to it long enough well. Who knows?


(Submitted September 14, 2007 09:56:13 by jim burns)

I'd like to buy one of these if someone has a functioning one to sell.


(Submitted September 12, 2007 10:30:27 by John McCartney)

I have one of these that is available. It comes with DOS and the original manuals, I think there's some other software there as well. Shipping from (or local pickup) Portland OR.


(Submitted July 27, 2007 00:57:07 by (a href=mailto:)Brian(/a))

To answer a couple of questions:

It is functionally an IBM-PC/XT—i.e. 8088 based, with up to 640kB of RAM without resorting to an Expanded Memory card. It should be able to run any version of MS-DOS. 3.30 is probably about optimal, for running from floppies.

Its weight is: fracking-heavy-oh-gawd-my-back. My memory of lugging the buggers suggests at least 40 pounds.

Ahh, the Luggable.

At one time i wanted to score one of these cases, and build my 286-12 (which was then living on a sheet of wood) into it. I had an ATI EGA wonder, which could drive interlaced 640x350 to a composite monitor, so it could have driven the Luggable's monitor. Would have been a nice upgrade.

I still have the hardware; i may yet do it, jsut because. :)


(Submitted July 22, 2007 17:05:17 by funkytoad)

What is its weight?

PS: I want to buy one

Hello, i got one of those portables. but when did the manufacturing started of this serie? i got one that has had his final test on 9 november 1984.


(Submitted June 10, 2006 17:06:35 by (a href=mailto:)Ziva(/a))

Can anyone tell me how to use its basic commands that come without DOS? Found an old one, and I have no idea what to do with it.


(Submitted April 5, 2006 17:11:47 by Kurt)

I used one of these, back around 1987-89, maybe later. We actually added a hard disk to it by running a ribbon cable out the back to a Seagate 10MB drive housed in an old tape drive box. Worked!
