Yes, a (external) FW SCSI terminator and a (external) SE SCSI terminator
at the (external) SE SCSI box.

I'm using the the 2.4 -kernel, and it says:

"The Zalon is an interface chip that sits between the PA-RISC
processor and the NCR 53c720 SCSI controller on K-series PA-RISC
boards (these are used, among other places, on some HP 780
workstations).  Say Y here to make sure it gets initialized
correctly before the Linux kernel tries to talk to the controller."

Well, since the C240/C3000 are 780-series machines, I wasn't so sure ...
