Sharp PC-E500 (S)
The Sharp PC-E500 was a pocket computer made by Sharp that could be programmed in BASIC .
The built-in programs covered the areas of mathematics ( whole numbers , equations , differential calculus , integral calculus , formulas and graphics), physics , chemistry , biology , geology , electrical engineering , mechanics and statistics . In addition, physical constants and the periodic table of the elements were available. However, it was not possible to automatically transfer a result to another program.
The Sharp PC-E500 settled by Memory ( RAM cards), printer , RS232 - interfaces , cassettes and - floppy drives expand. The internal working memory (RAM) could also be expanded from the standard 32 KB up to 256 KB through a hardware change. This was automatically recognized by the operating system and made it possible to set up a large RAM diskette to store numerous of your own programs.
The power was supplied by four micro batteries (AAA), which were sufficient for around 70 hours of operation.

successor
The successor, the PC-E500S model, came onto the market in 1995. This was a bit wider, which also made the keys a bit bigger. The display had more contrast , and a hinged lid was used for the keyboard cover instead of the plastic slide. There were also four additional BASIC commands. Programs that were written on the original model could run on the successor model without any restrictions. In the opposite direction, however, this only applied if the additional BASIC commands were not used.
