I deleted the mac address in the set list of my isdn router. How can I
restore it? I can't find it printed anywhere on the router either...

show interface ethernet 0 will say something like

router# show interface ethernet0
Ethernet0 is up, line protocol is up
Hardware is AmdP2, address is 00d0.c0f0.7c20 (bia 00d0.c0f0.7c20)

Where the bia address is the burned in address.

But bias address also shows 0000.0000.0000..........

Can I "take" another Cisco MAC address and use it as long as those two
routers never will be on the same network?

If not, you are free to use the below, I'm sure that my 1700 and
your 803 will never meet.
