The TCS was planned already in 1989, when Bjarne Lassen joined BAO. With his great interest in electronics in general and stepper motors in particular, he was the master mind behind the project. But the project was delayed again and again due to lack of time. The TCS was installed and ready for operation in the spring of 1993.
The 80286 PC is talking to the PC in master control of the whole TCS via an RS-232 line operating at 115200 baud. At given intervals, the TCS PC is receiving information about the step counters values and sending commands to move the telescope to a new position.
