I have a SecureKey Zorro II board (by DKB Software), which I used a long time ago in a A2000 (with KickStart 2). This board provides a keyword protection, which can be bypassed only by removing the board from the machine.

When I now tested it in my A4000T/CSPPC, there was this message on the screen the board opens:

"Security ID is unrecognizable. Please call for assistance."

Mouse pointer did not move, either.

Is this board incompatible with Kickstart 3, or A4000T? I do not have nowadays any other classic machine to test it with...

Regards,

Gregor

The SecureKey board contains a Dallas DS1204U chip (from looking at the board pic on amiga.resource.cx).

The DS1204U contains an embedded lithium battery which has probably died, hence the error message. Apart from that the rest of the board probably works fine. I don't know if it's possible to recover/fix that. Perhaps by disassembling the board ROM code it would be possible to figure out something.
