Hardware inventory:
Item             Version  Part number  Serial number     Description
Chassis                                53842             M40
Backplane        REV 02   710-001348   AW5314
Power Supply A   REV 08   740-000235   002219            DC
Power Supply B   REV 08   740-000235   001428            DC
Maxicab          REV 08   710-000229   AT3624
Minicab          REV 03   710-000482   AP2514
Display          REV 08   710-000150   AH9621
Routing Engine                                           RE-1.0
SCB              REV 02   710-001838   AP9468            Internet
Processor II
    SSRAM bank 0   REV 02   710-001385   0015022           2 Mbytes
    SSRAM bank 1   REV 02   710-001385   0015018           2 Mbytes
    SSRAM bank 2   REV 02   710-001385   0010947           2 Mbytes
    SSRAM bank 3   REV 02   710-001385   0015021           2 Mbytes


So you can see above that the SCB IPII (PFE) has 4 banks of 2M = 8M
SSRAM, I'm Guessing the 16M version has 4*4M

The 64Mb DRAM shown bellow is the Memory used by the Power PC that
is also on the SCB.
