Hi
I have just got hold of two 16533.
I inspected the boards and noticed that the PCB is infact of a 16534 and that it was relabelled 16533.
I have also noticed 2 resistors that have been changed near the main chip.
The two values are 1MOhm and 0.
I wonder if this is an attempt to change the card to 16534?
Anybody has detailed pictures of the two boards, so that I can compare them?
Thanks
