Macintosh Classic: Should Have Internal SCSI Terminator


I recently set up a Macintosh Classic single floppy with an external SCSI
hard drive, but could not get the hard drive to boot. When I ran SCSI
Probe on that Macintosh it tells me "bus not terminated".

Is the SCSI bus not terminated on the motherboard of the single drive
Classic? If not, can I get a terminator that can fit on to the
motherboard's SCSI port?

The Macintosh Classic is (or should be) self-terminated internally, through
the use of an internal SCSI Terminator. This is similar to the Macintosh
IIfx Internal SCSI Terminator, and plugs into the internal SCSI port on the
Classic's logic board. If you're missing the terminator, or you need to
replace it, the service part number is 630-0408.
