Save config on old Cisco Cat 6006

This is going to be an easy one for you, but I can't seem to save the config of a Catalyst 6006 for the life of me.

I thought I could simply type "write mem", but memory is not an option for the "write" command.  Then after doing some research it seems that I have to enter "text" mode first, so then I tried "set config mode text" and then "write memory", but still doesn't work.

Here is what happens when attempted:
Console> (enable) set config mode text
Usage: set config acl <nvram>
Console> (enable) wr mem
Usage: write network [all]
       write terminal [all]
       write <host> <file> [all] [rcp]


Please help, I am not used to these old switches :)

Thanks a ton!
