When the emulator starts, it reads the file cyber.ini which configures the emulation environment. The file typically contains multiple sections of the following form:
[SectionName] ; comment line keyword1=value1 keyword2=value2,value3
A typical “cyber.ini” might look like this:

Each section header is followed by a number of lines specifying parameters to the emulator. By default you need to have the section [cyber]. This can be overridden by a command line parameter when starting the emulator.
The first section is typically named [cyber]. It defines some basic emulation parameters such as central memory size, what deadstart panel and equipment sections to use. It has the following parameters:
| Keyword | Values | Description |
|---|---|---|
| CEJ/MEJ | 0 or 1 | 1 (default) enables CPU exchange jump feature |
| clock | 1 - 10 | Clock multiplier used to match real time clock to wall clock. |
| cpus | 1 or 2 | Number of CPUs |
| deadstart | string | Name of the section containing the deadstart panel settings. |
| displayName | string | Title to display on DtCyber console window |
| equipment | string | Name of the section containing the equipment definitions. |
| ecsbanks | 0, 1, 2, 4, 8 or 16 | Number of ECS banks. |
| esmbanks | 0, 1, 2, 4, 8 or 16 | Number of ESM banks. |
| helpers | string | Name of the section containing pathnames of helper program start/stop scripts |
| idle | on/off | Enable or disable CPU idle detection |
| idleCycles | integer | Number of idle cycles triggering CPU idle detection |
| idleTime | integer | Amount of time to sleep when idle detected |
| memory | octal number | Central memory size (1000000 is a good value). |
| model | CPU model | Name of the CPU model to be emulated |
| npuConnections | string | Name of the section containing definitions of NPU/MDI features |
| operator | string | Name of the section containing operator commands to be executed during startup |
| ostype | string | Name of the operating system type to be supported by the configuration |
| persistDir | string | Pathname of directory in which to store system state |
| pps | 12 or 24 | Number of PPUs (octal value) |
| setMhz | integer | Cycle counter speed, in Mhz |
| trace | integer | Establish debug trace mask |
The section named by the “equipment” keyword in section “[cyber]” defines the attachment of peripheral equipment to channels, their equipment and unit numbers, and in some cases file names or other parameters. The following shows the general syntax of an entry:

The section named by the deadstart keyword in section [cyber] defines the Cyber deadstart panel settings used to load PPU 0 with a short bootstrap program. The deadstart panel settings are up to 16 octal values (one per line) representing the deadstart switch settings.
