The VAX 4000 Model 200
base system components are housed in two different enclosures:
the BA430 enclosure, which contains a 12-slot Qbus backplane, and
the BA215 enclosure, which contains a 6-slot Q-bus backplane.
Each
base system contains the following:
• A KA660–AA/BA (M7626–A/–B) central processing
unit (CPU) module
• From one to four MS650–Bx memory modules.
|
|
 |
| |
The base system modules
are located in the following card slots:
• MS650–Bx memory modules are installed in slots 2 through 5.
• The KA660 CPU module is installed in slot 1.
The base system operates from
the KA660 CPU firmware and the controls on the CPU cover panel. Base system
operation also integrates Digital
Storage Systems Interconnect (DSSI) technology |
