Sharp
PC-7000

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.

We need more info about this computer ! If you designed, used, or have more info about this system, please send us pictures or anything you might find useful.
Please consider donating your old computer / videogame system to Old-Computers.com or one of our partners from anywhere in the world (Europe, America, Asia, etc.).


 

I recently restored a PC-7100 and it''s a really cool little machine. The CPU is a soldered 8086 which can operate in a 7.37mhz or 4.77mhz "compatible" mode. Expansion options included a modem and video port, my model does not have either of these. The hard disk was on a hardcard and wired to a non-standard port, mine had this removed unfortunately. The FDD had an eject button rather than a lever and uses a canon 1/3 height drive and supported 5.25" DD. The FDD interface can handle a 3.5" DD or a GOTEK with DD images. The Parallel port is non-standard and does not support much more than "nibble" modes, it also does not support any sort of communication with cd-roms, zip drives, back pack hard disks or sound devices (covox). I was able to get a Compact-Flash to Paralell (Shuttle interface) to work over nibble but its painfully slow. The screen is horrible by todays standards but impressive for the time - it did support CGA mode "2" and Mono/Text but is completely unsuitable for any games except text adventure. Windows 3.0 is possible using the CGA driver and looks pretty decent. RAM is expandable to 764KB and the motherboard itself is very small and beautifully laid out (as was the style of many japanese electronics back in that time)

We had many hand me down computers growing up but this is the one I loved the most. Maybe it was that pack up portability or super crisp text on the screen. I remember spending hours playing in a text editor...exploring all the menu items to see what they would do. If anyone has a PC-7000 and wants to sell it let me know nelson1707 at Mac.com

Hi, my dad owned the Sharp 7100 and i assume like the 7100 the 7000 does not have a internal Batterie (except for BIOS)
It only had a big 3 Pin Powersupply.

I learned programming on that the 7100- loved it.
The internal display only was capable displaying Letters (i think it was 25 Lines and 80 Columns letters)
the 7100 had an external Monitorport (I think it must be the 15 Pin that is often called vga-port but i don''t know if it was VGA or CGA or something)
Only the external display was able to display graphics (i had to switch to another graphicmode to enable the external display and then i could draw sprites into the videoram).
With the square on the right you can change the angle of the display to come out a bit and there was a weel at the top of this square to change the contrast.

i can confirm the 7100 has a 20mb harddisk and one 5 1/4 floppy drive.

some years ago i heared my father has thrown it away :''( (even if it was still working and had absolute no damages or scratches)
