OK - here's what I'm looking at.
Based upon the hardware I worked on (and documentation for the 642 system), apparently it's BE based:
Register representation on panel: R bits 29 .. 0
where MSB is on the left and LSB on the right.
Memory is 30 bits (just like registers) and is physically spread over 5 chassis with 6 bits of each word stored on each chassis:
chassis 1 : bits 5 .. 0
chassis 2 : bits 11 .. 6
chassis 3 : bits 17 .. 12
chassis 4 : bits 23 .. 18
chassis 5 : bits 29 .. 24
If you look up to my third post you can see the basic setup of how a word is interpreted for instructions, with all calculations based on the msb .. lsb concept.
