Hi, Nick

Not sure whether t200 and t200a are software compatible. The t200
is known to work. The eeprom dump gives me the impression (not sure)
that your board is stuffed with another tuner.
Please have a closer look at the board. Do you find a chip tda9889?
and a small tuner metal can?
If you find the tda9889, the driver for the t300 might work.
To get it, you will need to load the saa7134 module with
modprobe saa7134 card=70
A picture also might help.

Good luck
