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.
Seen from the back the Portable PC has all of the ports and slots typical of an IBM XT.
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.
System and associated items Donated by Michael Woo
if anyone has one of these to donate or sell at a reasonable price, i'd be interested.
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!!
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.
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!
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!
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?
I'd like to buy one of these if someone has a functioning one to sell.
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.
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. :)
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.
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.
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!
