  Hi all
 I was told that VAX-11/750 memory could also be used in an PDP-11/70 (or
 maybe some other model). Is this true? 
Yes. :-)
  I have also read that there are three kinds of memory
boards for the
 11/750:
 M8728: 256k byte memory array;
 M8750: 1M byte memory array;
 M7199: 4M byte memory array.
 (As well as some third party boards.
 Which one of these, if any, could be used in an 11/70? 
Only the 256K ones.
