# System Configuration
## Introduction
An utility applicaton that sets NVR Attributes that affect HBIOS and
RomWBW Operation. Write to RTC NVRAM to store config is reliant on HBIOS
## Building
TASM (Telemark Assembler) ([Anderson, 1998](##References)).
### RomWBW Version
Is part of the SBCv2 RomWBW distribution. And deployed as a Rom Application
It is included in Rom Bank 1
### CP/M Version
The resulting `sysconfig.com` command file can be run in CP/M.
It is copied in the Binary/Apps folder.
