VAXserver/MicroVAX 3300/3400
Conversion
This chapter describes how to convert from a VAXserver 3300/3400 system to a
VAXserver 4000-200 system and from a MicroVAX 3300/3400 system to a VAX
4000-200 system using a 660XR-XX conversion kit.
Caution
The MS650-AA memory module will not function with a KA660-XX
CPU module. When a KA640 CPU module is removed and the system
is converted to a KA660-XX system, install an MS650-BA (16-Mbyte)
memory or MS650-BB (8-Mbyte) memory.
