Long shot. The 3000 is the only model (I think) that backs up more than just the RTC with the battery. A few system variables are stored as well. I thought they were about the SCSI interface only. Maybe not. I believe there is a utility on Aminet that resets the variables to factory defaults. I can't remember the name, but, it shouldn't be hard to search.
IIRC, OS2.04 had the latest speech revision before C= stopped including it in the OS. You're lucky to have it.
