Hi Eric!

Hope you didn't pay much for it ;-)

Usually only 2Mb each :-(

>... I obtained a vt320 ... unable to ... display anything on the vt320.  I

The default console output of a DECstation 5000/120 is via the graphics.
Unlike other types of workstations, DECstation does not automatically
switch to serial console if output via graphics is not possible.
Connect the vt320 to serial3! and try to connect a keyboard to the
keyboard port. After "boot" the keyboard should do keyklicks. Type blind:

setenv console s

This should switch output to vt320.

To the LED code:  oxxo  oxxo  : Memory bank 0 could not be initialized.

btw: this was an inspiration to do:

a hand-made copy of the table that lists the LEDcodes in the manual. :-)

Control the conections of your simms. The memory modules should be set
two at a time in one bank#:

correct:  1  mmmnmmm   mmmnmmm  false:  1  mmmnmmm   -------
          2  mmmnmmm   mmmnmmm          2  mmmnmmm   -------
          3  -------   -------          3  mmmnmmm   -------
          4  -------   -------          4  mmmnmmm   -------
          5  -------   -------          5  -------   -------
          6  -------   -------          6  -------   -------
          7  -------   -------          7  -------   -------
          8  -------   -------          8  -------   -------


hope this helps

Anton
