# How to install ! Nova RDOS on Wild Hare Nova emulator?
|
|
|
|
|
|
|
|
We can run [! Nova RDOS](/1970s/1972/nova-rdos) on the Wild Hare Nova emulator. First, we need to download the ! Nova RDOS disk image.

You can download the disk image needed to run ! Nova RDOS on the Wild Hare Nova emulator from the [Wild Hare Legacy Preservation Website website](http://www.novasareforever.org/):

## Using ! Nova RDOS
|
|
|
|

|
|
|
|
If you have not already installed Wild Hare Nova emulator, see [the VirtualHub Setup tutorial on how to do so](https://setup.virtualhub.eu.org/wh-nova/) on Linux and Windows.
|
|
|
|
:::
|
|
|
|
Create a folder somewhere to store the files for this VM and move the disk image you just downloaded into it. Now we will create a config file for our VM. Create a text file called `nova.ini` with the following content in the VM folder:
|
|
|
|
```ini
|
|
set CPU Eclipse_S/140
|
|
set PTR enable
|
|
set PTP enable
|
|
set PLT enable
|
|
set LPT enable
|
|
set DSK disable
|
|
set DEP disable
|
|
set DKP enable
|
|
set DZP enable
|
|
set TTI1 enable
|
|
set TTO1 enable
|
|
set ALM enable
|
|
set TTI bs swap
|
|
set TTO bs
|
|
dep TTO time 200
|
|
set TTI1 bs swap
|
|
set TTO1 bs
|
|
dep TTO1 time 200
|
|
set RTC MIPSsec=5
|
|
set DZP0 6067
|
|
attach DZP0 DZP.6067.RDOS.raw
|
|
deposit DZP stime 1000
|
|
deposit DZP rtime 1000
|
|
```
|
|
|
|
|
|
|
|
Now open a terminal and move to the VM folder. Run the following command to start the emulator:
|
|
|
|
```bash
|
|
nova
|
|
```
|
|
|
|
|
|
|
|
There are different versions of RDOS for different models of Nova computer. They are:
|
|
|
|
- URDOS
|
|
- MRDOS
|
|
- NRDOS
|
|
- ZRDOS
|
|
|
|
If you want to run URDOS, run the following commmand at the `sim>` prompt:
|
|
|
|
```bash
|
|
set CPU NOVA
|
|
boot DZP
|
|
```
|
|
|
|
|
|
If you want to run MRDOS, run the following commmand at the `sim>` prompt:
|
|
|
|
```bash
|
|
set CPU NOVA_840
|
|
boot DZP
|
|
```
|
|
|
|
|
|
If you want to run NRDOS, run the following commmand at the `sim>` prompt:
|
|
|
|
```bash
|
|
set CPU NOVA_4/X
|
|
boot DZP
|
|
```
|
|
|
|
|
|
If you want to run ZRDOS, run the following commmand at the `sim>` prompt:
|
|
|
|
```bash
|
|
set CPU Eclipse_S/140
|
|
boot DZP
|
|
```
|
|
|
|
When prompted `Filename? `, type the name of the type of RDOS you want to run. For example, for NRDOS, type `NRDOS` and press enter.
|
|
|
|
When asked for date, enter it in `MM/DD/YY` format. For example, enter `04/13/74`. Keep the year in 1970s or 80s, to avoid any issues. Similarly, when asked for time, enter it in `HH:MM:SS` format. For example, enter `12:55:31`.
|
|
|
|
Now you can type `LIST` and press enter. It will list all the files available on the disk.
|
|
|
|
|
|
|
|
That's it! We used ! Nova RDOS. We can create a shell script to make it easy to launch the VM.
|
|
|
|
### Linux
|
|
|
|
Create a file called `Nova-RDOS.sh` with the following content:
|
|
|
|
```bash
|
|
#!/bin/bash
|
|
nova
|
|
```
|
|
|
|
Now make the file executable:
|
|
|
|
```bash
|
|
chmod +x Nova-RDOS.sh
|
|
```
|
|
|
|
Now you can start the VM using the shell script. For example, on KDE you can right-click the file and choose `Run in Konsole` or on GNOME, where you can right-click the file and choose `Run as executable`. The VM will start.
|
|
|
|
See the [manuals section](/1970s/1972/nova-rdos/#manuals) on the [main ! Nova RDOS page](/1970s/1972/nova-rdos/) to learn how to use it.
|
|
|
|
### Windows
|
|
|
|
Create a file called `Nova-RDOS.bat` with the following content:
|
|
|
|
```bash
|
|
nova
|
|
```
|
|
|
|
Now you can start the VM by double-clicking the shell script. See the [manuals section](/1970s/1972/nova-rdos/#manuals) on the [main ! Nova RDOS page](/1970s/1972/nova-rdos/) to learn how to use it.
