from FAQ:
S/40 - S/42  --- added disc caching, implemented in software.
S/44 - S/48   /
S/42 - S/52  --- Memory ctlr update to support 2 and 4 MB memory
S/48 - S/58   /   boards. Also, updated CPU to support various
                  system table expansions and slight processor speed
                  enhancement.
S/64 - S/68  --- Added support of a 3rd I/O bay.
and reduced backplane signals, requiring Kelly RAMdisk to use bank switching
S/68 - S/70  --- Increased CPU (not disc) Cache for a rather
significant increase in CPU speed.
