In the early 1980s, after IBM introduced the PC, there was a rush to market of a wide variety of clones and work-alike systems. In that lot the Compaq was a notable machine due to its portability. Eventually folks realized that 30+ pounds just wasn't portable and the era of the laptop was born. (Actually, Tandy/Radio Shack had a portable PC available prior to the IBM-PC and several companies had calculator style PCs as well, none with tons of power.)

Sharp's answer to the portable market was one of the first ever clamshell designs featuring a full keyboard and a full 80 column display, albeit only 8 lines of 80 columns.

The Sharp wasn't 100% IBM-PC compatible but it did run MS-DOS and many PC programs (some modified to the screen.)

The Sharp was very unique, however, in that it used bubble memory for persistent storage.

Sharp PC 5000 bubble memory

The bubble memory was packaged in cartridges that plugged into a slot on the machine. These acted as 128KB disks.

The boxed Sharp PC 5000

This Sharp PC (Portable Computer) came with it's original box, packing materials and documents. It is pretty much new.

The Sharp PC 5000 manual

Even the manual is in new, almost unread, condition.

The Sharp PC-5000 is an Intel 8086 based 16 bit machine with 128k of RAM. Expansions would allow for more RAM, an attachable printer and a separate set of 5.25" floppy drives.

Wondering if anyone who has this system (Sharp PC- 5000), can confirm the power supply specs are 12vdc @ 850ma, center negative. I got one on ebay, but no pwr supp.

This was my first computer! It had an optional thermal printer, which could be installed into the unit by removing a plastic cover plate. It was slow and poor quality so I didn't keep it. Did buy the optional 5.25 drive and CRT display interface, but programs were hard-coded to run in 8 lines. Yes, it was PC-DOS, but NOT MS-DOS compatible. It did run Basic and a word processor and calc program. The Tandy was the better portable at the time, I think, but it used cassettes for storage.

I have a Sharp PC-4600 with 2 720K floppy drives and a 512K RAM memory drive that still works. I boot with DOS 6.2 and copy MS Works into the RAM drive. I would be willing to donate to a museum or collection rather than junk.

I've found an Sharp PC-6200 with floppy drive and extra external battery pack in my attic. It's in great shape I'm not sure if it works but if someone is interested please make me an offer.

I have a bubble memory cartridge for the Sharp 5000 with a WP app on it (Wordstar?) I remember that the cartridges were horribly expensive at the time they were released. Does anyone you know if there is a market for these cartriges now?

Sorry I'm off topic a bit but I just picked up a Sharp PC 6200 with the expansion/floppy drive interface for 5 dollars at a garage sale. I thought it would was just a word processor. I am wondering if I could add a bigger HD and some more memory. It is 640k, 20meg now.
