OPTIONAL HARDWARE

Third-party products which conform to the Bitbus Standard.

CLUSTER ENVIRONMENT 

For the DECscan VMS Driver:

This layered product is fully supported when installed on any valid
and licensed VAXcluster* configuration.  It must be installed once on 
each VAX, MicroVAX or VAXstation processor from which usage is planned.

In order to configure some product specific attributes that must remain
unique to each system, certain components of the  product are stored in 
the  system  specific  environment,  SYS$SPECIFIC:[SYSxxx], of the  VAX, 
MicroVAX or VAXstation processor on which the installation is performed. 
The remaining components of  the product, including  some or all of the 
executable images will be installed common to all accessing systems.

The HARDWARE REQUIREMENTS sections of this product's Software Product 
Description and System Support Addendum detail any special hardware 
required by this product.

* V5.x VAXcluster configurations are fully described in the VAXcluster 
  Software Product Description (SPD 29.78.xx) and include CI, Ethernet 
  and Mixed Interconnect configurations.

For the DECscan ELN Driver:

This layered product is fully supported when installed on any valid
and licensed VAXcluster* configuration without restrictions.  The HARDWARE 
REQUIREMENTS sections of this product's Software Product Description and
System Support Addendum detail any special hardware required by this product.

*  V5.x VAXcluster configurations are fully described in the VAXcluster
   Software Product Description (29.78.xx) and include, CI, Ethernet, and 
   Mixed Interconnect configurations.

ELN Target Systems

Finished VAXELN systems can be loaded and run on an IVAX (KA620,KA630)
MicroVAX II, MicroVAX 3500/3600, VAXstation II, VAXstation 3200/3500.
A VAXELN target system typically requires a memory configuration of 1MB and 
a ROM based application could have as little as 256 Kbytes of physical memory
on the target system depending on the size of the user's programs and on the
toolkit  components  that  are  included.   
The target computer must have a load device for loading  the  VAXELN  system
image.  The load device is either a TK50, RX50 or Ethernet adapter 
(for downline loading).  VAXELN Target systems can also be placed into ROM.
                                                                  
SOFTWARE REQUIREMENTS

VMS Operating System V5.0
MicroVMS Operating System V4.4 - V4.7

For the VAXELN Driver

The VAXELN Toolkit, V3.0 must be installed on the host which is to 
receive the DECscan VAXELN driver.  Refer to VAXELN Toolkit (SPD
