DEC could no longer source quantities of blank TK50 or older supported media for those installs and upgrades. Which meant those VAX systems need entirely-feasible but less than easily supported shenanigans for performing OpenVMS VAX installations and upgrades. Nothing was done to OpenVMS VAX to prevent those VAX systems from booting, and OpenVMS VAX V7.3 will boot and work just fine — assuming sufficient main memory available, and assuming a system manager / admin knowledgable in shuffing OpenVMS VAX installers around and with some spare / swappable storage ardware. -- Pure Personal Opinion | HoffmanLabs LLC
