Notes

The Sun-3/110 and Sun 3004 CPU must be 501-1134-06, 501-1163-09, 501-1164-09, or greater. All 501-1208 and 501-1209 revisions are usable.
When four or more ALM-2 boards are installed in a system, the part number must be >=501-1203-05 because of the mechanical fit of the data cables.
An addressing conflict can occur between the ALM-2, MCP, and ALM-1. Refer to the VME Installation Notes in the Slot Assignments chapter.
