... which has two 4-Bit CPUs (!) from Sharp, SC43177 und SC43178 labeled, driven with only 256 KHz (yes, KILO not MEGA). This was my first "Computer" I had, and I loved it, because I was able to use the Pocket Computer at school (think about an electronical cheat sheet) also.
Unfortunately it had only 1424 BASIC steps (implemented with 3 4KBit RAMs.... still wondering how this could work), so not too much for larger projects.

This is my own one:


Remarkable also is the rare yellow LCD display (later this intensive yellow color can't be found anymore).

One of the successors of this first Pocket Computer was the PC-1500, which owns - guess what - a Z80 compatible CPU - perfect to program it also in assembly language.

Unfortunately the Assembly language for the above mentioned PC-1211 was never published, so any kind of extension or graphics can't be programmed on a PC-1211 :-(
