Untested but believed to work, this was dropped off at my desk this afternoon. It has some kind of locking device in the floppy drive slot, and the case lock is locked with no key. No idea what's in it, but it will probably need the HDD thoroughly wiped before passing on. Free to a good home. Apply within.
Can you put up a picture of the Key type ( entry point on theh computer) IBM had a very small selection of keys , and I think I may still have some in a box of bits as I am going through thye old company stuff that was left in the workshop when it closed down back in about 2005.
