Access to the PROM card in previous VAX versions and older PDP versions that were upgraded to a VAX version is through the top using the following procedure:
SITE CONTROLLER HARDWARE
Verify that the Site Controller computer is a VAX model, or a PDP model that has been upgraded to a VAX model (see the VAX Site Controller heading in the Applications Notes section). If you find that the Site Controller computer is a PDP model, upgrade kits are available through Ericsson Service Parts. Alternatively, the PDP model may be replaced with the current 19A149302P9 VAX model.
SITE CONTROLLER SOFTWARE
