TNS SC
It was manufactured from 1985 by JZD AK Slušovice.
The computer was inspired by or was successor to TNS ST. Hardware is based on U880D @ 2,5MHz.Operating systems running on the computer: TNS-DOS(TurboDOS),CP/M,COBRA.

On TNS-SC computers, bootloaders are reported as "D1>" or "D2>". The method of booting the operating system varies according to the recording density on the system diskette.
If it is a floppy disk with a single recording density, the system is booted by pressing the [S] ( single ) key and then pressing the key with the number of the disk unit in which the system diskette is inserted. For example, for drive 0, the key sequence is: [S] [0]
If it is a diskette with a double recording density, then the [D] key ( double ) is used instead of the [S] key. For
so disk drive 1 will be the key sequence: [D] [1]
On the TNS-SC/W, if the computer is not adapted for automatic loading from a Winchester disk, the operating system is loaded similarly.
The TNS-SC(/W) computer can be equipped with 5 1/4" drives. In this case, it is possible to use the INT module from the TNS-MC computer and boot the operating system in the same way as on the TNS-MC.
