The PC-7000 is Sharp’s second computer targeted for sale in the US, after the PC-5000 from late 1984.
First previewed in July at the 1985 “National Office Machine Dealers Association” show in Las Vegas, the PC-7000 was available for retail three months later in October.
While the PC-7000 is not the first transportable computer by any means, it may have had the best built-in display of any – a huge 9.5 x 4.25-inch electroluminescent backlit LCD screen capable of displaying 24 lines of text, with 80 characters per line.
The computer offered IBM compatibility, dual built-in 5 1/4-inch floppy drives, and relatively light weight made the PC-7000 one of the best portable computers of the day.
Sharp always had a reputation for building technically sound but rather stange computers, ignoring ‘industry standards’. The PC-7000 broke this image.
This was a “lunchbox” portable IBM PC compatible system. It had two 5”1/4 disk-drives mounted on the right side and a nice blue tiltable screen, the world’s first backlit LCD.
The system consisted of three main parts: system unit, keyboard and optional CE-700P printer. When the system had to be carried, both the keyboard and the printer clipped into the main unit.
One year later (1986) , the PC-7100 was launched. It had a 20Mb hard-disk instead of the second built-in 5”1/4 FDD.

The computer is modular in terms of accessories, an 20MB external drive can be attached underneath and a thermal printer on the back. I found a picture on Reddit with the HDD but I haven’t found the printer on the web. It clearly exists as the printer is mentioned in the user manual.
I got my machine pretty dirty and it needed cleaning. Sure, some retrobrite would be great but I really like the yellow color on this particular unit. Here’s a picture with the unit disassembled and squiky clean:
I made a video with the PC-7000 that I will share soon. Some attention was needed on the dual FDD unit, the internal 3.6V battery etc.
