VAXserver/MicroVAX 3500/3800
Conversion
This chapter describes how to convert from a VAXserver 3500/3800 system to a
VAXserver 4000-200 system and from a MicroVAX 3500/3800 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 KA650 or KA655 CPU module is removed and
the system is converted to a KA660-XX system, do the following:
1. Install an MS650–BA (16-Mbyte) memory or MS650–BB (8-Mbyte)
memory module.
2. Remove the H3600 CPU I/O panel and install the H3602 I/O panel.
The H3602 panel is included in the conversion kit.
