My two earliest brochures are the pre-CX days when the machine was
called the System/3000:

System/3000 Software General Information        11/71
HP System/3000 System Description               11/71

Both of these clearly show a picture of the ISS (2888) drives.

The other brochures are dated:

7900A Cartridge Disc Subsystem                  9/72
7970E Digital Mag Tape Subsystem                10/72
2614A Line Printer                              9/72
2660A Disc Memory                               4/72
2600A Display Terminal                          9/72
HP 3000 Computer System Summary Description     2/73
2888 A Disc File                                2/73
2892A Card Reader                               2/73
