Don't trust it's calculator design : it's a BASIC computer
Special features :
- A very funlook for a BASIC pocket computer!
Weak points :
- All the weak points from it's grandfather the PB-100 (more memory, though!:), plus the alphabetic keyboard!!

That's a very funny experiment from Casio. On one hand, it has a vertical design, a 12 characters display and a simple numeric keypad just like simple 4 operations calculators.
On the other hand, it has a foldable alphabetic keyboard just like antique databanks. It's none of the above, though!!
Or should i better say "it's more than both of the above alltogether"?... Just like the calculator, it will perform simple calculations in RUN mode (This is the mode the device is in when switched on).
With the MEMO mode, it acts just like the antique databank we mentionned : it will store simple lists of data and allow for keyword searches.
Now, what it does offer more is of course BASIC programming!
To be honest, this "computer in disguise" look is actually the most exciting "feature" of this device... The small memory and display size are quite a limitation. It also lacks a little twist that would make it really different...
If it wasn't a collectible item, i could certainly use it with home-made programs for some everyday situations at work : it's clearly designed for simple program access and easy numeric data entry, and does very good on that part.
