        Actually, the first time I saw Thread Manager was in System 7.1.4...

        The "SCSI Manager 4.3" extension was included in System 7.5, and upgraded
to "SCSI Manager" in System 7.5.1 (version 4.3.1). It was then rolled into
Systems 7.5.2 & 7.5.3...

        Also, SCSI Manager 4.3 was included in the firmware of the 660AV & 840AV,
and PowerMac 6100, 7100, 8100, & WGS 9150. The firmware was upgraded to
4.3.1 in the 6100/66, 7100/80, 8100/100 & 110, WGS-9150/120, & Radius
81/110...
