I had one of these back in 1998 I believe it was. Needed something I could store some phone numbers in and quick notes. I didn't have a cellphone at the time and this fit the bill nicely. 1997 to about 2001 were what I call the "HPC Haydays". HPC stands of course for Handheld Personal Computers. Casio, Compaq, Psion and a slew of others had top of the line (and price!) palmtops out like the Philips Velo and the Casio Cassiopea A-11/20. These demanded a big price, so some companies saw the market to make "cheaper" versions of these machines. That's where the Sharp OZ 770 comes in. I bought mine in the U.S. for about $39.99 at Office Depot after lusting over some Psion 5's which were out of my price range. Anyways, I bought it and went straight to the car. I ripped the packaging open and powered it on. "Bliss" I said, entering a couple of quick phone numbers to try it out. It's a great little Palmtop, it's got a clear LCD display and plenty of memory for notes and phone numbers. (This isn't a video playing machine so 3mb will be more then enough!) It lasts quite a while on the batteries which you can get anywhere. It's also rather durable. The plastic, although it can get easily scratched won't crack. Not easily at least. So you don't have to worry about leaving it in your backpack while tossing it around. Be warned though, these palmtops were at the lower end of the palm top market. Mass produced for the folks who didn't want a palmtop which cost as much as their laptop. That being said, some people on eBay (and other places) charge and OUTRAGES sum of money for them. These are probably worth 15 to 20 U.S. dollars and not the 200+ dollars they sell for on eBay! But to recap: Pro's: Great clear screen which is easy to read even in direct sunlight. Decent back light. Good amount of memory for text like memo's and phone numbers. Batteries last a long while and can be bought anywhere. (AA type) Durable plastic which will help the unit last for a long time. Con's: Cheap screen showing only numbers/letters unlike their more expensive cousins. Scratches easily. PC sync cables require serial ports, not sure if a serial to USB adapter will work. Ridiculously priced on eBay! Again, over all I give this a strong 8 out of 10. For what it is, you won't find anything like it. Don't use a cellphone? Well here you have everything you need to stay in contact without the actual phone!Read full review
A lot of people aren't familiar with the full capability of the Sharp 700 series. All of these are cross compatible from the OZ-700 all the way to the OZ-770. The 750 had more Sram though, built-in 256k of ram and 2.5mb of Flash. The 770 has 3 MB of flash and went back to 128K Sram. Other than that they are identical. All of this was directly addressable by the CPU. Yes, you read that correctly, the flash and ram are all addressable as pages of memory. Using the z88dk SDK development kit, it is possible to write programs in C on this machine with bitmapped graphics, software sprites etc. Contrary to some reviews, this device is more than capable of bitmap graphics(239x80 pixels). You can download software to do just about anything including spreadsheets(which can be transferred to excel), and long documents up to 16,000 characters each. You can write code on this machine, compile it on your laptop or desktop, and then come back and test it on your wizard. It uses a Z80 processor running at 9.8 mhz. In addition, the powerful Daytimer software DB is transferable to Microsoft products. It has RS-232 serial as well. This means that the creative user can do anything that a serial port offers! That means USB conversion as well! Even RS232 to Ethernet. Communicate with Any parallel or serial driven device. This is provided of course that the user develops the code for doing these things using the SDK. Standard out of the box, it can do sync, and program transfer. I have a USB to RS232 adapter running on COM 3. Works great! There is also a BASIC SDK for this machine which is very similar to GW-BASIC for MSDOS. The 'Loader' program allows you to store up to 19 programs at the same time. The Downloader allows you to put your own software or software written by others on your wizard!. Bacon allows you to program short BASIC programs as memos and load them...this gives you nearly unlimited space for short programs! As for the organizer portion, you can place larger documents on it, and then read them all with the "write" software. Separating each into 2K spanned segments, as pure memos, or with the write program it is invisible to the user. you can read whole books. There is an eBook reader for it called Librarian which can be installed and used. A program called Memoedit allows for 16K memos (that's 16,000 characters per file). As for the rest of it, it is SOOOOO handy to have. It is way better and easier to use as an information storage device than any phone. Full qwerty means you have a mobile productivity machine that is unmatched in terms of battery life, viewable graphics display, and functionality. Whatever you end up paying for one of these, it is worth it! One of the best pocket devices I have ever come across!Read full review

I have been using a Sharp OZ-770PC Organizer since they came out many years ago. I have tried other organizers and always come back to this. It's small enough to carry around...can put your phone numbers, birthdays, anniversaries, appointments....all very easy to use. I wish they didn't stop making these new!

This device may be tech from 20 years ago, but it has a great functionality even today. It holds memos, phone numbers, addresses, etc. It has a great calendar that goes till 2099! If you can get one with a non defective screen (missing pixels can develop), then go for it! It's really refreshing to use a device that runs on 2 AA batteries and needs no recharging.

The Sharp OZ-770 as the best organizer ever made. They were ultimate organizer product before the entire product type was made "obsolete" by very small PC's, and they are still best for the functions they perform – storing telephone numbers, short memos, etc. You can transfer the valuable data stored on the organizer to a regular Pc for safekeeping in case the organizer or its data is lost. That also allows me to down load the data to another OZ-770 if necessary. I really liked this particular buy because when it arrived it was better than advertised and I got it for a very good price all things considered. It will make an excellent "spare" in case something happens to my original 770.
