I found this at the back of my docset. It's too faint to scan... I'm transcribing it from hand.

Page 14, HEADER, on last paragraph - add: Effective on Commodore 9060 and 9090 disk units, serial numbes greater than 2313, a format drive command (such as a HEADER command, Basic 4.0; or a New disk command, Basic < 3.0) will take approximately 55 minutes for a 9060 disk, and 1 hour 45 minutes for a 9090 unit to properly format the disk. 2. Page 8, under NOTE - add the following: On disk power-up, if it is necessary to test the unit to verify that the drive is up to speed, without waiting the 60 second delay recommended here in the Preliminary Disk Reference Manual, units with Rev B roms would be tested by issuing a READ (128) command to the drive. Units with Rev C roms should issue a TEST DRIVE READY (168) command to the drive in place of the READ command. Units with Rev C roms may be differentiated from units from Rev B by accessing (reading) memory location 65510 (FFE6 hex). Rev B roms will contain a 170 (AA hex) in that location, while Rev C roms will contain a 12 (0C hex). ===== Infinet has been sold. The domain is going away in February.
