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) - author: Tim date: Saturday 18th August 2018 text: We had many hand me down computers growing up but this is the one I loved the most.

What I would be inclined to do is try to find an eariler version of dos. say maybe ibm dos 3.0 and boot from that and attempt an install. You could try booting off your dos 5.0 disk (it should be bootable) but I dont know how happily it will run on that machine so again I would recommend tring to get hold of an earlier version of dos on 5" 1/4 floppy, have a look on ebay there are a few copies floating about. Alternatively there is a version of DOS out on the net called free dos. It is built for varying architectures, some quite old such as the intel 8086 cpu. If you have another computer that has a 5" 1/4 drive you could create a boot disk and give free dos a try. From you post it does seem like the machine should run, probably just some problem with the hard drive that hopefully can be sorted out with a simple format and install of dos.

I had two young children at the time, and thought a portable computer would give me some versatility to move to different rooms in the house - which it did. It was considered pretty capable, as I recall, because of the 8086 processor. Other portable units didn''t have the full, detachable keyboard - a key selling point for me, as I recall.

First machine I had with an IDE hard disk, although it had an overheating issue. The machine actually had a packet sniffer card in and sniffer software (can't remember the make) and was stickered up with special keypresses and the Sniffer company's logo's. I suppose it could be an early "appliance". The sniffer card was a full length ISA card - the slot was in the base of the unit with the ports appearing on one end of the main box. Keyboard was a joy and the screen pretty good too, I thing it was CGA compatible but the video port could have been EGA. Cable tucked neatly into a slot in front of the screen with a spring-loaded flap on it (you can just one edge of the slot below the left hand edge of the screen in the pic.

Two disk drives, no hard disk, upgraded to 768K RAM, upgraded with a CGA monitor output port. Couldn't run some games porperly (Flintstones Lost in Bedrock would freeze after the title screen is displayed, Alleycats would periodically hang, Buzzard Bait and PC-Man would not read keyboard presses), but I could actually get the machine to run in "Dual Display mode", in which the onboard LCD display ran in monochrome mode and the connected display would display CGA graphics (some programs, notably SignMaster, could take advantage of the configuration and use the monochrome display for editing and the color display for output sampling). Has a 3-pin power connector, RS-232C DB25 serial port, a centronics parallel port around the back (upgraded models would also have a 9-Pin CGA port). The keyboard is connected to a port around the side. Keyboard has a special key that allows one to go directly into the BIOS and make changes that can take effect on the fly. Changes includes time and date settings, speaker volume, printer behaviour, Serial port behavior, and LCD behavior (off/monochrome/graphics, normal/inverse ). All in all, nice machine.

From the menu, choose the SETUP option by entering the number 4 and then pressing the keyboard ENTER/RETURN key....the SETUP routine will now start to appear on screen. 5\. Follow the SETUP screen prompts, making each selection ...DATE...TIME...etc. 6\. When the listing of options is shown, review to assure that they represent your PC-7200/7221.

Does anyone know where I could find a keyboard for it, due to RJ 11 (Phone/Ethernet) cable used for it. - author: Tom Dwelly (UK) date: Friday 12th September 2003 text: |- I just got hold of a "SpiderSystems SpiderMonitor PC200" from a clear out at my university (I dunno why they still had it hanging around). Well, after taking the thing apart (I couldn't resist), I discovered that its actually a PC7100 with a fancy NIC in the expansion slot (and some tasteful decals of course).\ I can't see myself using it as is, especially as its not booting, but some of the bits may be useful. So the question is, does anyone know if its possible to get the LCD panel working independently? Pin-outs or such like would be useful too. Any help would be much appreciated. - author: Pat McNeil (Canada) date: Thursday 24th July 2003 text: |- Hello - does anyone have the pinout for the keyboard connector for the Sharp PC7100? (I imagine the other models 7000 are the same?) I have a machine here that boots from the internal HD, but I can't work w/it as I don't have a cable. It' a phone cable w/6 conductors, but it isn't a straight through, it seems. Anyone with a cable that can check this for me?

This was about ten years ago. I didn't find anything I thought was of value back then. I have just rediscovered them and am keen to get the LCDs out and use them as displays for CPU temp, fan speed, network throughput etc, on newer computers. Does any know where I might be able to find out what type of LCD and controller chips they use, and how to wire them up?

(nothing like a good ol' game of the original pacman or paratrooper!) oc_id: 496 source: url: https://web.archive.org/web/20230608082939/http://www.old-computers.com/museum/computer.asp?c=496 date: '2023-06-08' --- 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.
