My first computer was a luggable. That was the name for the awkward adolescent phase of a reverse growth spurt computers were making in the late 1980s. The era of room-sized computing was over, and early enthusiasts had desktops in their home office, but no lap was big enough for this device to sit atop. The iconic elements that define laptops today were emerging though: the screen on a hinge that folded over the keyboard, the ability to run on a battery. The giveaway that clearly defined the IBM PC Convertible as a luggable was the integrated handle, which let you carry it around like a suitcase.

Beyond its luggability, the name provided a clue that something more innovative was at play — this thing could expand! To make the core of the computer as small as possible, the keyboard, grayscale display, and dual floppy drives were all housed in a base unit that provided basic functionality at the smallest size. Modules could then be snapped on the back to add additional capabilities, extending its length (and weight) but integrating into a seamless whole. I had the modules for extra ports (serial and parallel), and the adapter to drive an external CRT display. I also had the module that gave the PC Convertible its most distinctive capability: an integrated thermal printer.


Stacked together, the assemblage nearly touched the ground when held from its handle. The printer was like a secret capability, hiding its mechanical identity behind a pop-up plastic door. It printed like a fax machine, burning crisp black characters into the same rolls of thermal paper that would fade to nearly unreadable gray outlines within a month. If your goal in owning a printer was to get data off of easily corruptible floppy disks onto a more archival substrate in the physical world, then this module was a clear failure. But if you defined success by the mere possibility of printing ASCII art banners on the go, then the PC Convertible was truly game-changing!

IBM launched the PC Convertible in April of 1986, and it was discontinued just three years later. It was already well put to pasture by the time I got mine, around 1992, when my Mom bought it at a garage sale or auction. New at retail, my setup would have cost over $3,000, but if I remember right, she paid just $25. Surprisingly, for the era, this wasn’t the first computer in our house. That would be the green-screen desktop in my Dad’s office that he used to manage his farm. I had a few games I was allowed to play on his computer, but there was always the specter of screwing it up somehow. The PC Convertible was mine to explore.
Even by the standards of the time, it was incredibly limited. No hard drive, and the floppy drives only supported double-density (720K) disks, not the newer high-density (1.44MB) versions. But I didn’t really register the limitations because it was the first time I could root around and figure out how things worked. I futzed with shareware games (shoutout to Babbage’s at the Portage Crossroads Mall), but what really captured my attention was the command line. It came with IBM PC DOS 3.2, spread out over multiple floppies, and I would spend hours running each command just to figure out what they could do.
This wasn’t yet programming, but it was my first introduction to computers as spaces of possibility and experimentation. Up until then, I’d watched my Dad use his computer like a single-use device, following written instructions on how to load and operate the programs he needed for his business. But here, on my own machine, is where I learned to see computers as general-purpose technology, with capabilities you could string together to do something new. What I discovered, in something as simple and limiting as a DOS batch file, was the mental reframing of a computer from an appliance to a platform.
It wasn’t long before I was able to move beyond the PC Convertible, to a hand-me-down Packard Bell desktop with a 40MB hard drive and a 256-color monitor. That led to modems, discovering the BBS world, and eventually the Internet. But that old luggable has a special place in my heart, and it’s the only computer I’ve kept in storage and still own today.
Museum Worthy
I’ve come to terms with the fact that I’m old enough for childhood artifacts to be museum-worthy, and it’s been nice to run into variants of my first computer at museums and swap meets around the world. That’s also made me realize that mine is in pretty good condition, and that I’m lucky to have both the printer and external CRT display.
As an artifact of design history, the IBM PC Convertible has been collected by the Centre Pompidou in Paris, along with some of the original design sketches and prototypes created by the industrial designer Richard Sapper. I would love to see these someday, in particular this gorgeous prototype made out of wood, cardboard, and paper.
