The X1cs, as well as the [X1ck](/museum/sharp-x1-ck-cz-804c/), are derived from the [X1c](/museum/sharp-x1-c-cz-801c/). They are low price models.
The difference between X1c and X1cs, is that the X1c can be connected to a 4 colors plotter/printer, whereas the X1cs has two I/O ports instead of the plotter/printer connector.
Tape Basic and Disk Basic were available but had to be loaded from tape.
