Index Simulators Web based SSH
Our simulators are based on the publicly available SIMH codebase.
A variety of simulators are available. When you open one, all relevant files are copied to your home directory under ~/simulators before the simulator is started. This means each simulator is personal to you-you're free to modify anything, including the simh.ini files.
If you want to create a new simulator from scratch or maintain multiple copies of the same simulator, there are two easy ways to launch them:
From the shell:
Run timedial-start-sim <sim_name>.
For example, if your simulator is in ~/simulators/mysim, you would run:
timedial-start-sim mysim
From the menu:
Add or edit a simulator.toml file inside the simulator directory.
Below is a sample configuration file used for one of our existing simulators:
[emulator] # Required
label = "PDP-11 with 2.11BSD"
command = "pdp11 pdp11.ini"
[description] # Optional
publisher = "BSD"
original_date = "1978"
version = "2.11"
version_date = "1992"
text = [
"Digital Equipment Corporation's famous 1975 PDP-11/70, running 2.11BSD!",
"This mini-computer is fully decked out with 4MiB of memory.",
]
login_information = [
"Username: root / Password: None",
"At the boot prompt (:), press Enter to boot.",
"At the single-user prompt (#), press Ctrl+D to enter multi-user mode.",
]
Only the [emulator] section is required-the rest is optional and can be customized as needed. Once the simulator.toml file is updated, your simulator will appear in the main menu of TimeDial.org.
To conserve disk space, all emulator disk images are automatically compressed when you're not using them and uncompressed when you start. This process takes just a few seconds and can reduce image sizes by as much as 98%, depending on the contents. The compression is seamless and does not require any manual intervention.
