This is the compact version of the [Sharp X1](/museum/sharp-x1-cz-800c/). No new features except the size and the VRAM (48 KB instead of 4 KB).

The most famous and strong feature of the X1 series is Programmable Charactor Generator(PCG).

Tape Basic and Disk Basic were available but had to be loaded from tape.
