Can anyone elaborate on the technique to get the I/O cover off the case? The Service Manual on TOS leaves me wondering how to exactly do this.
I am trying to troubleshoot two card readers I have, one does not read cards (Checksum and Card Error messages) and the other appears to have a bad ROM as it is not even recognized with CAT 2.
I hope I can make 1 good from both or does anyone have parts?
