What is SBTCVM?

Ever wonder what computers other than the boring-old binary would be like? Well, look no further! SBTCVM, a python-written VM, simulates the little-known base number called Balanced Ternary!

What is balanced ternary? well, it has "0" and "+1", just like binary, but added into the mix is a "-1"! Yes, this means EVERY number is signed.

Intrigued? Well, as SBTCVM is Free & Open Source Software, and comes with a ready-to-use set of compilers and development tools, Getting started with balanced ternary with SBTCVM, should prove a fun challenge!

Features:

• bundled ternary software. including demos, games and utilities.
• 4 channel sound chip
• 6.5Khz, 9-trit CPU
• 3.25Khz 9-trit Coprocessor
• 39.388 KiloNonets of system RAM
• pygame frontend features color graphics.
• multiple specialized programming languages with integrated compilers. (SSTNPL, SBTCVM assembly)
• Suite of development tools and utilities.
• cross-platform interactive shell and build system. (xas.py)

Dependencies:

Python 2.7 OR 3.

Sound (all frontends) (powered by FSSynthlib): pygame

gfxcon.py: pygame (used to process images)

Curses VM frontend: curses

Pygame VM frontend: pygame (needs truetype font and PNG support!)

Install instructions:

1. Ensure python is installed.
2. Ensure pygame and curses are installed for your system's default python installation.
3. keep downloaded files in a place you can easily access.
4. DO NOT try to move/change the default directory structure!
5. proceed to the Getting started guide

Filing bug reports

SBTCVM Should in theory work in any Operating system with python (2.7 or 3), pygame, and curses.
If it does not, or you have hit some other sort of bug, please file a bug report stating your

• python version
• pygame version
• Operating system
• along with a description of the problem.

Note: please consult the Troubleshooting guide BEFORE filing a bug report!

at the SBTCVM Gen2-9 issue tracker on github. Please try and read though existing issues to see if its a known bug.

notes for linux software packagers:

• SBTCVM is SINGLE USER
• The official name of this specific version of the SBTCVM Suite is: SBTCVM Gen2-9
• The user needs access to the vmuser directory.
• any desktop entries should include one that starts the XAS shell (run xas.py with no arguments) in a terminal emulator.
• the python executables & utilities ARE NOT designed to be used from arbitrary directories. further they will all change their working directory to their location automatically.
• the official, current, SBTCVM icon can be found in vmsystem/GFX

Code Licensing

SBTCVM gen2-9 ships with fssynthlib.py, a general-use waveform synthesis library from the FSSS synthesizer suite. You can find its readme in the textdocs directory.
