The Service manual for the SS 4 is still available from (harcle ...)

A small search thru google will find it.

In fact: snarf as much doc/sw as you can.

Breaking in ? a suitable cd-reader eases the pain or is the boot monitor
(forth monitor) password protected ?
If the prom is unlocked, "boot -s" will bring up the machine in single

Or, does it boot ? try to break into it over the network.

Depending on configuration it can be easy.
