Convergent Technologies Workstation password recovery/reset

Picked up this beast at thrift store this morning. It's a Convergent Technologies Workstation made by Unisys. Powering it up produces the following (my added comments in parentheses): T *************** L (hard disk activity begins here, LED '1' lights up) ................................... ................................... ................................... ................................... ..... (screen clears) a240MstrpMP-9.1/00 (screen clears) SysInit 9.15 There will be a momentary delay as the system now begins loading $JOB Sysinit,, Execution begun: Sat Mar 1, 1952 12:00M $RUN [d0]<sys>InstallQMgr.run Termination status code: 0 $RUN [d0]<sys>InstallSPL.run Termination status code: 0 $Run [Sys]<Sys>SPrint.run (4 beeps here) Termination status code: 0 $END Execution ended: Sat Mar 1, 1952 12:00M (screen clears) SysInit 9.15 LUTHERAN SOCIAL SERVICES OF CO System Signon User Name Password Date/Time ----- There's a reference to a company in Minnesota called Service Information Systems, but their number has been disconnected. Probably dead or bought out and absorbed years ago. A Unisys Service Identification tag on the back of the CRT has: Service Number TP-191050 Style Number OM-1001 ZZ and a tag at the base of the unit has: Convergent Technologies Workstation Product Number 99-01640 Serial Number A-26671 This is mounted next to a tag stating 'No User Servicable Parts' (along with dire warnings about voiding your warranty, burning your extended family at the stake, and having your knees broken with baseball bats by guys with crooked noses named 'Vinny', should you dare to open the case.) I'd like to be able to clear the original owners' information off the drive and start over, but I'm unfamiliar with the OS and haven't had any luck getting past the login. Unisys has remade itself as an e-Business Solutions Provider, and their website has no useful information; a call to their tech support produced responses of 'Uhhh...' and 'You have a what?' along with muffled laughter. I think the 'a240MstrpMP-9.1/00' means that it's running CTOS 9.1, but I haven't been able to dig up any useful info on the unit itself, or the OS. Any ideas?
