The Casio PB-1000 was a handheld computer released by Casio in 1987.

Folded, the calculator was quite small but once open, it showed large keypad and screen.
Its special feature was its touchscreen display which consisted of 16 keys built into the screen on a four by four matrix.
The computer itself included 8Kb of RAM and it was possible to install the RP-32 card for a 32ko memory expansion .
The PB-1000 was programmable in both a Casio version of the BASIC language and an assembly language.
A ROM card could be added for CASL assembly for the educational COMET simulator.
It could be completed also by the MD-100 which provided a 3.5 floppy disk or by the FP-100 & FP-40 printers.
Because it was a complete system for the time, the calculator has been used for many years by business companies for their accounting or operational follow-up.
A special release of this computer, called PB-1000C provided C language but it was difficult to find in Europe.
