I have a manual for the N* HRAM series which I'd be happy to copy and send
you - email me. There are some differences between revision B and E boards
and there are lots of jumper options. In summary, S1 and S2 select the
active memory areas, JP1 selects the bank status on reset and selects I/O
control bits for bank switching and parity, JP2 selects areas to be bank
switched, JP3 selects the parity error response, JP4 implements the First
Quadrant option (only revision E 48K version), and JP6 is reserved (no
jumper).
