Ok. I opened the telex machine and found the following details.

8088 pc chip 2 telex cards (for 2 lines) model No. 405-2 Chipset of the telex card AMD-8085A-2PC /P8085A 8135 EP.

There are two 9pin cables connecting the telex cards to a DC/DC converter (what's that) There's a 360 KB floppy drive on the system with some system files. The floppy never used to work earlier, the drive cable was loose. The floppy contained some files command.com, autoexec.bat, start.com, duend.com (what's that). The machine does not need the floppy to boot. so the system's operating system must be on a boot rom.
