  Here we go again... :-)

  In order;

1) its a SIMM pinout they dreamed up themselves.
2) Yes.
3) No.

  Ralph and I beat this one to death a couple of weeks ago.  You may want
to try and look up some old articles.

  Basically, there are two JEDEC standard SIMM's.  x8 (or x9 w/parity)
30 pin SIMM's and x32 (x36 w/parity) 72 pin modules.  GVP chose to bring
out their own 64 pin x32 module.
