You should be able to boot from the bootstrap-diskette, as it doesn't use the stuff on the hd until it tries to mount the root.
Can the machine boot from hd?
Do you get the boot: prompt, so you can enter -s to go to single-user?

I would make a fresh installation floppy, and upgrade the whole system, in case hacked executables are installed, and then double-check what is run from inetd and misc rc-files.
